Intro
Understanding the risk factors associated with colorectal cancer is paramount in combating the disease. With rising incidence rates worldwide, especially in developing nations, shedding light on these influences becomes ever more essential. This examination digs deep into aspects that contribute to colorectal cancer, marrying genetic components with lifestyle choices.
The focus stretches beyond what is commonly known; it aims to tease out subtler threads linking various risk factors to the complex tapestry that is colorectal cancer. Among many elements, dietary habits play a significant role, alongside broader lifestyle choices like physical activity and socio-economic conditions. Moreover, age and family history also weave their way into the discussion, illuminating a holistic view of colorectal cancer risk.
By unraveling these layers, we seek not just to inform, but to empower individuals, healthcare professionals, and researchers alike. Understanding these factors enriches the narrative on prevention and awareness, ultimately leading to better health outcomes.
As we embark on this exploration, we aim to foster deeper discussions, raise awareness, and enhance understanding across multiple disciplines, setting the stage for informed dialogue in both academic and public health settings.
Preamble to Colorectal Cancer
Colorectal cancer stands as one of the leading causes of cancer-related deaths worldwide. This stark reality underscores the importance of understanding the various risk factors associated with it. This introduction sets the stage for a deeper examination into what contributes to this complex disease. In order to tackle this ongoing health challenge, one must peel back the layers, much like the very cells involved in this particular type of cancer.
Defining Colorectal Cancer
Colorectal cancer refers to the malignancy that arises in the colon or rectum, which are integral parts of the large intestine. To paint a clearer picture, it begins when cells in these regions start to grow uncontrollably. The growth can result from various factors, including genetic predispositions and environmental triggers. In many cases, it builds on the foundation of non-cancerous growths, or polyps, which can develop into cancer over time if left unchecked. The entire process is influenced by a host of elements, each contributing to the eventual tumor formation.
The Importance of Understanding Risk Factors
Understanding the risk factors of colorectal cancer is not merely an academic exercise. It's a pressing need for prevention and early detection. Recognizing what sets the stage for this disease can empower individuals to make informed decisions regarding their health. Risk factors can range from genetic conditions, like familial adenomatous polyposis, to lifestyle choices, such as diet and physical activity. Moreover, specific populations might be more susceptible due to socioeconomic conditions, making it essential to map out these influences comprehensively.
"Knowledge of risk factors provides a pathway to prevention, allowing individuals and communities to combat colorectal cancer more effectively."

Having this understanding can also steer public health initiatives, shaping screening guidelines, and ultimately reducing the incidence rates of colorectal cancer. When we delve deep into these risk factors, we begin to uncover strategies that could potentially save lives and improve outcomes. As we continue this exploration, the connections between these factors will reveal just how interconnected our health choices and biological makeup truly are.
Genetic Risk Factors
Understanding the genetic risk factors associated with colorectal cancer is managing the big picture of how this disease can develop. Genetics play a pivotal role by influencing one's susceptibility to this form of cancer. Particular hereditary syndromes and gene mutations stand at the forefront of this issue, providing researchers and healthcare professionals insights that can facilitate both preventive and therapeutic approaches. Notably, identifying individuals with these genetic markers can lead to earlier screenings and interventions, enhancing outcomes and survival rates.
Hereditary Syndromes
Familial Adenomatous Polyposis
Familial Adenomatous Polyposis, or FAP, is a hereditary condition caused by mutations in the APC gene. A hallmark of this syndrome is the development of hundreds to thousands of polyps in the colon and rectum, usually starting in the teenage years or early adulthood. If left untreated, these polyps can become cancerous before the age of 40.
The key characteristic of FAP is its aggressive nature regarding polyp formation, making it a critical focus in discussions about colorectal cancer risk. The importance of recognizing this condition lies in its potential for earlier intervention. Early surveillance and preventative surgery can substantially reduce cancer risk, allowing individuals to lead productive lives with reduced anxiety about their health.
Some unique features of FAP include extracolonic manifestations, such as desmoid tumors and osteomas, which can also lead to health complications. This broader spectrum of risk emphasizes the necessity for multidisciplinary care and continued research into the long-term effects of living with FAP. The downside? Regular and often invasive screening procedures are essential, creating a medical burden that can be challenging for families.
Lynch Syndrome
Lynch Syndrome, also known as hereditary nonpolyposis colorectal cancer (HNPCC), accounts for a significant portion of hereditary colorectal cancer cases. It's linked to mutations in mismatch repair (MMR) genes, thereby impairing DNA repair mechanisms. This dysfunction can lead to the accumulation of mutations over time, spiking cancer risk.
The defining feature of Lynch syndrome is that individuals not only face heightened risks for colorectal cancer, but also for other cancers such as endometrial and ovarian cancer. This complexity makes Lynch Syndrome an intriguing subject within the larger discussion of cancer epidemiology. An advantage is that genetic testing can identify carriers, potentially prompting proactive measures such as increased screening or prophylactic surgeries.
However, the intricacies of Lynch syndrome add layers of complexity; individuals might face an emotional burden knowing they carry such a serious genetic defect. Furthermore, recommendations for cancer screenings vary widely, making it crucial for affected families to stay informed about the need for personalized medical management.
Gene Mutations and Polymorphisms
KRAS and BRAF Mutations
The KRAS and BRAF mutations play vital roles in the signaling pathways that lead to cell growth and division. Mutations in these genes are prevalent in many colorectal tumors and are associated with a more aggressive disease course. For example, the presence of a KRAS mutation can significantly affect treatment decisions, often making conventional therapies less effective.
What makes KRAS and BRAF mutations crucial to discuss is their impact on personalized medicine. Specialists can tailor treatments based on whether these mutations are present or absent, which can lead to better patient outcomes and more efficient use of healthcare resources. However, a disadvantage comes with the heterogeneity of mutational status; not all patients will respond to targeted treatments in the same way, complicating treatment landscapes considerably.
TP53 Genes
The TP53 gene, often dubbed the "guardian of the genome," is integral in controlling cell cycle and apoptosis. Mutations in TP53 can hamper its ability to repair DNA or initiate cell death, contributing to tumor development. Its mutations are commonly found in colorectal cancers, linking it closely to adverse prognostic outcomes.
A significant aspect of TP53 mutations is the timing and occurrence of these mutations, which often appear later in the pathway toward colorectal cancer progression. This characteristic allows researchers to study cancer development over various stages, enhancing understanding of the disease. On the flip side, this delays recognition of risk, as patients may not be screened or monitored as rigorously until later stages when treatment becomes more complex and less effective.
Genetic factors are just one piece of the puzzle, but understanding them is vital for ongoing research into colorectal cancer prevention and management.

Age as a Major Risk Factor
Understanding the impact of age on colorectal cancer is essential, not just for medical professionals but for anyone who wishes to grasp the landscape of this prevalent disease. Age serves as one of the most significant risk factors; as individuals grow older, their likelihood of developing colorectal cancer increases dramatically. This escalation in risk can be attributed to a multitude of biological and lifestyle changes that manifest over time.
Adolescence and early adulthood aren't typically domains of concern when it comes to colorectal cancer. However, by the time people reach 50, the statistics begin to tell a different story. It's always been said, "With age comes wisdom," but unfortunately, it also brings an increased risk of illness in many cases, including this one.
Age Distribution and Incidence Rates
Colorectal cancer incidence rates are not distributed evenly across age groups. Research has shown that approximately 90% of colorectal cancer cases are found in individuals aged 50 and older. To put it in perspective:
- Young Adults (under 40 years): Rarely diagnosed, accounting for only a small fraction of cases.
- Age 40-49: This group is also less frequently diagnosed but should increasingly consider early prevention strategies.
- Age 50 and beyond: Incidence begins to rise steeply, emphasizing the need for vigilant screening.
"The most significant shifts in diagnosis occur as age increases, highlighting the importance of starting screenings early at age 45 or even younger for those with a family history."
"The most significant shifts in diagnosis occur as age increases, highlighting the importance of starting screenings early at age 45 or even younger for those with a family history."
Current guidelines recommend that most individuals begin screening at 45, and earlier for those at elevated risk. The stark reality is that as individuals cross that milestone, early detection becomes paramount. Each year past 50 primes the body for genetic mutations and polyps that could eventually develop into cancer.
Importance of Screening in Older Adults
As mentioned earlier, the older population is particularly susceptible to colorectal cancer. Screening plays a crucial role in catching the disease at an earlier, more treatable stage. Not only does it save lives, but it also significantly reduces the healthcare costs associated with advanced cancer treatment.
Some critical aspects to consider about screening include:
- Different Screening Methods: Colonoscopy, flexible sigmoidoscopy, and stool tests are among the options available to the elderly; each has its unique advantages and limitations.
- Tailoring the Approach: Older adults may have various health concerns that require customized screening schedules to ensure safety and accessibility.
- Awareness Campaigns: Given the unique challenges faced by this demographic, public health campaigns aimed at increasing awareness of the need for regular screenings can significantly impact early detection rates.
In summary, age is not merely a number; it serves as a crucial marker in the fight against colorectal cancer. Staying informed, recognizing risk factors, and understanding the importance of screenings can ultimately shape the choices made by both individuals and their healthcare providers.
Engagement with this topic is essential—not just for the sake of knowledge but for actionable steps that could prevent lives from being lost unnecessarily.
Dietary Influences
Diet plays a crucial role in the risk of developing colorectal cancer. Research highlights that what we consume can either protect or predispose us to this disease. A well-balanced diet, rich in nutrients and devoid of harmful substances, is fundamental to reducing these risks. Various components of our diet, from meats to fibers, can have a significant impact on both the development and prevention of colorectal cancer. Understanding these influences empowers us to make informed food choices.
Red and Processed Meats
Red and processed meats are often the subject of scrutiny in discussions about cancer risks. Studies have shown that high consumption of these meats correlates with an increased risk of colorectal cancer. The mechanisms at play include the presence of certain chemicals formed during meat cooking at high temperatures, such as heterocyclic amines and polycyclic aromatic hydrocarbons. Furthermore, processed meats, like sausages and deli meats, may contain preservatives such as nitrates, which have been linked to cancer.
It's important for individuals to evaluate their daily intake of these kinds of foods. Some strategies to minimize risk include:
- Limiting Intake: Reducing the amount of red and processed meats can be beneficial. Aim for smaller portions and replace them with lean proteins when possible.
- Cooking Methods: Opt for cooking methods that avoid charring or smoking, as these can form harmful compounds.
- Incorporate Alternatives: Utilize plant-based proteins such as beans or lentils in place of meat when feasible.
Fiber Intake and Whole Grains
Fiber is a dietary component that has garnered considerable attention for its potential protective effects against colorectal cancer. A high-fiber diet can facilitate digestion and regular bowel movements, thus potentially reducing the time that harmful substances are in contact with the intestinal walls. Different sources of fiber, especially whole grains, fruits, and legumes, contribute significantly to lowering cancer risk.
Key factors to consider regarding fiber include:
- Types of Fiber: The two types, soluble and insoluble, work in concert to promote gut health. Soluble fiber helps lower cholesterol and manage blood sugar, while insoluble fiber aids in digestion.
- Whole Grains: Foods like oats, brown rice, and whole wheat bread are packed with fiber. Including these can help ensure adequate fiber intake.
- Recommended Intake: Adults should aim for at least 25 to 30 grams of fiber daily, yet most do not meet this recommendation.
Alcohol Consumption and Colorectal Cancer
The relationship between alcohol consumption and colorectal cancer is quite intricate. Research suggests that excessive drinking may elevate the risk of developing this cancer. Alcohol can act as an irritant to the gastrointestinal tract, leading to inflammation. Moreover, it is known to interfere with the body's ability to absorb nutrients and break down toxins efficiently.
When considering alcohol intake, it is essential to:
- Moderate Consumption: Limiting alcohol intake to no more than one drink per day for women and two for men may crucially reduce risk.
- Consider Type of Beverage: Different types of alcoholic drinks may exhibit varying potentials in contributing to cancer risks. The evidence seems particularly strong for spirits compared to beer or wine.
Impact of Fruits and Vegetables
Fruits and vegetables are paramount in any diet, and their impact on colorectal cancer risk cannot be overstated. These foods are rich in vitamins, antioxidants, and phytonutrients. The contributions of powerful compounds found in fruits and vegetables can help combat oxidative damage, leading to reduced cancer risks.
Some pertinent points regarding fruits and vegetables include:
- Variety is Vital: Consuming a wide variety of colorful fruits and vegetables ensures a broader range of nutrients. Dark leafy greens, berries, and citrus fruits are exceptional choices.
- Antioxidant Power: Foods rich in antioxidants may reduce inflammation, one factor in cancer development.
- Plant-Forward Eating: Diets high in fruits and vegetables encourage healthy gut flora, which contributes positively to digestion and overall gut health.
Having a plant-forward diet that emphasizes fresh fruits and nutritious vegetables is a cornerstone in the fight against colorectal cancer. Emphasizing these foods may offer a protective buffer against cancer growth.

In summary, dietary influences on colorectal cancer risk encompass a range of factors. Cutting down on red and processed meats, maximizing fiber intake, moderating alcohol consumption, and loading up on fruits and vegetables can make a considerable difference. Being mindful of these factors not only contributes to potential cancer risk reduction but also promotes overall health and well-being.
Obesity and Physical Activity
Obesity and physical activity play critical roles in the landscape of colorectal cancer, influencing disease risk through a variety of mechanisms. With obesity rates climbing globally, understanding its correlation with colorectal cancer is not just timely but vital for public health. The connection between these two elements offers insights useful for both prevention strategies and patient education. Maintaining a healthy weight and incorporating physical activity can be powerful in mitigating some of the risks associated with developing this type of cancer.
Body Mass Index (BMI) and its Correlation
Body Mass Index (BMI) has long been a litmus test for identifying obesity, and its relevance in relation to colorectal cancer has garnered considerable attention. BMI is calculated by taking a person’s weight in kilograms and dividing it by the square of their height in meters. High BMI values are linked to a greater risk of various cancers, including colorectal cancer. This could stem from a few different reasons:
- Hormonal Changes: Obesity leads to changes in sex hormones and insulin resistance, both of which may promote tumor growth.
- Chronic Inflammation: Excess body fat can lead to chronic inflammation, creating an environment conducive to cancer progression.
- Altered Gut Microbiota: Evidence suggests that obesity can change the composition of gut bacteria, potentially leading to increased cancer risk.
The relationship is not merely statistical; real-world effects come into play, making it paramount to assess not just weight, but lifestyle choices as well. The simple truth is that the heavier one is, the higher their risk of developing wannan disease.
Role of Exercise in Risk Reduction
Exercise, often touted for its myriad health benefits, shines brightly when it comes to preventing colorectal cancer. Like two sides of the same coin, exercise complements dietary measures in reducing cancer risk. Engaging in regular physical activity can tilt the odds in favor of health rather than disease. Studies have shown that even moderate amounts of exercise can help lower the risk significantly, transforming sedentary habits into protective ones. Specific benefits include:
- Weight Control: Regular physical activity plays a crucial role in maintaining a healthy weight.
- Enhanced Digestion: Exercise promotes better bowel movement and digestion, helping the body eliminate harmful substances more efficiently.
- Hormonal Regulation: Physical activity helps balance hormone levels, which could impact tumor growth.
A combination of aerobic exercise, weight training, and simply getting up to move throughout the day can add up in protective benefits. The key takeaway is that moving more and sitting less is indeed a worthwhile pursuit.
"Exercise not only shapes the body but also fortifies the defenses against diseases, including cancer."

Inflammatory Bowel Diseases
Inflammatory Bowel Diseases (IBD) play a significant role in the discussion of colorectal cancer risk factors. IBD primarily refers to two chronic conditions: Crohn's disease and ulcerative colitis. Understanding these diseases is essential not only for grasping their direct implications on gastrointestinal health but also for recognizing their potential link to colorectal cancer.
The inflammation that characterizes IBD can disrupt normal cellular processes in the colon, leading to changes that increase cancer risk. For those diagnosed with IBD, the need for strict monitoring and management becomes critical not just for quality of life, but also for cancer prevention.
Patients suffering from IBD are often caught in a double-edged sword: while they bravely navigate their chronic condition, they must also bear in mind the elevated risk for colorectal cancer. Early diagnosis, regular screenings, and a tailored treatment plan play crucial roles in mitigating this risk.
Crohn’s Disease and Ulcerative Colitis
Both Crohn's disease and ulcerative colitis have distinct characteristics, yet their effects on colorectal cancer risk can be alarmingly similar. Crohn’s disease can affect any part of the gastrointestinal tract, including the small intestine. Its lesions can extend through multiple layers of the bowel wall, causing extensive scarring and complications. Conversely, ulcerative colitis is confined to the colon, where it primarily impacts the innermost lining.
Research indicates that individuals with longstanding Crohn’s disease or ulcerative colitis are at an increased risk for developing colorectal cancer, primarily because of the duration and severity of inflammation. The risk escalates significantly for patients who have been suffering from these diseases for eight years or more. Factors influencing this include:
- Severity and extent of inflammation
- Age of onset of the disease
- Presence of dysplasia (abnormal cell growth)
Preventive strategies typically involve more aggressive management of IBD. Patients may be advised to undergo regular colonoscopies to monitor for precancerous changes. The aim is to catch any cellular abnormalities early on, ideally before they can progress.
Long-term Effects of Inflammation
The connection between chronic inflammation and cancer formation is well-documented. Over time, ongoing inflammation can cause damage to the DNA within cells. This damage may lead to mutations that disrupt normal cellular functions, which can eventually give rise to colorectal cancer. In IBD, the repeated cycles of injury and healing create an environment ripe for carcinogenesis.
Understanding the long-term effects of inflammation also opens doors for preventive measures. Here are some considerations for managing inflammation to mitigate cancer risk:
- Medications: Anti-inflammatory drugs, immunomodulators, and biologics can control inflammation effectively, reducing cancer risk.
- Surveillance: Regular medical check-ups with an emphasis on colon health are crucial.
- Lifestyle Choices: Diet plays a role as well. A diet high in anti-inflammatory foods—like leafy greens and omega-3 fatty acids—might lower the risk of inflammation.
- Stress Management: Chronic stress can exacerbate inflammation, making mental health a component of physical wellness.
In summary, the implications of inflammatory bowel diseases on colorectal cancer risk underscore the need for vigilant monitoring and management strategies.

While Crohn's disease and ulcerative colitis can complicate a person’s health narrative, understanding the risks and being proactive about prevention can make a world of difference in outcomes.
Family and Personal History
Understanding the role of family and personal history in the context of colorectal cancer is crucial for both patients and healthcare providers. Family history significantly impacts an individual's risk of developing colorectal cancer, often acting as a red flag for early screening and preventive measures. Moreover, a person's past medical experiences with polyps or other colorectal issues serve as vital indicators for future risks. By examining these elements thoroughly, we can appreciate how inherited traits and personal experiences shape cancer risk and influence health outcomes.
Family History of Colorectal Cancer
The significance of family history cannot be downplayed. When we talk about a family history of colorectal cancer, we refer to any direct relatives—such as parents, siblings, and children—who have been diagnosed with this type of cancer. The risks are magnified when multiple family members are affected, especially at younger ages. This genetic linkage often signifies a hereditary syndrome, making it essential for individuals with a familial background to engage in more vigilant screening and lifestyle modifications.
Key considerations regarding family history include:
- Increased Risk: Studies indicate that individuals with a first-degree relative diagnosed with colorectal cancer are two to three times more likely to develop the disease themselves compared to those without such family ties.
- Genetic Testing: For those with strong family histories, discussing genetic counseling may be beneficial. Conditions like Lynch syndrome or Familial Adenomatous Polyposis require proactive measures to monitor and mitigate risk.
- Awareness and Communication: Families should openly discuss health histories. This communication is pivotal for updating medical records and informing healthcare providers to tailor screening strategies accordingly.
"Family history is a powerful tool in understanding cancer risks; knowing it can be lifesaving."
"Family history is a powerful tool in understanding cancer risks; knowing it can be lifesaving."
Personal History of Polyps
Personal history plays a substantial role as well. If an individual has had adenomatous polyps removed in the past, they face an increased risk of colorectal cancer. Polyps, while typically benign, can progress to cancer over time. The context of their prior experiences with polyps sheds light on their ongoing cancer risk and screening needs.
Key factors related to personal history of polyps include:
- Type of Polyps: Different types of polyps present varying degrees of risk. Adenomatous polyps are considered precursors to cancer, so their previous presence requires careful monitoring.
- Follow-Up Screening: Individuals with a history of polyps generally have more stringent follow-up protocols, often necessitating colonoscopies at shorter intervals than the general population.
- Health Behavior Influence: Those who have undergone polyp removal may be more aware of their colorectal health, prompting proactive lifestyle changes. This awareness can lead to better dietary choices and increased engagement in regular physical activity, reducing overall cancer risk.
In summary, understanding both family and personal histories offers essential insights into the risk factors for colorectal cancer. Embracing this knowledge can shape preventive strategies and create pathways for early detection. By acknowledging the multifaceted nature of cancer risks, individuals can participate actively in their health management.
Socioeconomic and Environmental Factors
Understanding the role of socioeconomic and environmental factors in colorectal cancer is crucial. These factors impact not just individual risk, but also health outcomes on a community level. A person’s environment and economic status can shape their access to healthcare, as well as their dietary choices and lifestyle habits. The correlation between these factors and colorectal cancer risk cannot be overlooked in the broader discussion about prevention and awareness.
Impact of Socioeconomic Status
Socioeconomic status (SES) is a significant element that can directly influence one’s risk of developing colorectal cancer. People from lower SES backgrounds often face barriers in accessing quality healthcare, leading to delayed screenings and diagnoses. Studies suggest that individuals with lower education levels or income may engage less in preventive health behaviors. For instance:
- Lack of health insurance
- Limited access to nutritious foods
- Insufficient knowledge of health-related issues
These barriers contribute to a cycle of health disparities, where lower SES communities experience higher incidence rates of colorectal cancer. Efforts to improve access to healthcare and education around screening could lead to earlier detection and better outcomes.
Environmental Exposures and Their Risks
Everyday environmental exposures have been linked to an increased risk of colorectal cancer. Factors like pollution, industrial waste, and even the food supply can all play a role in influencing this risk. Some of the potential environmental hazards include:
- Chemical exposure: Pesticides, herbicides, and other chemicals used in agriculture may have detrimental effects on the intestinal flora, eventually leading to carcinogenesis.
- Air and water quality: Long-term exposure to pollutants can lead to chronic inflammation, a known risk factor for developing cancer.
- Occupational hazards: Certain industries expose workers to carcinogens, such as those involved in manufacturing or construction.
Understanding how these factors interplay helps to illuminate the larger picture of colorectal cancer incidence.
Preventive Measures
Preventive measures play a critical role in reducing the risk of colorectal cancer, emphasizing the significance of early detection and lifestyle modifications. As the saying goes, an ounce of prevention is worth a pound of cure. Understanding how to minimize risks can not only lead to improved health outcomes but also elevate the quality of life in individuals predisposed to this disease. In this section, we will delve into two vital components: Regular Screening Guidelines and Adopting a Healthy Lifestyle. Each will explore how proactive steps can significantly influence one’s risk level.
Regular Screening Guidelines
Screening for colorectal cancer is crucial for catching issues before they escalate into something more severe. The guidelines for regular screening have evolved based on advances in medical research and technology. Health professionals recommend that individuals at average risk begin screening at age 45, though those with a family history or other risk factors should consult their doctors about earlier screening. There are several methods available, including:
- Colonoscopy: This procedure allows for a thorough examination of the entire colon and rectum, with the ability to remove polyps during the same visit. Typically recommended every ten years for those at average risk.
- Fecal Immunochemical Test (FIT): This non-invasive test, which can be done at home, detects hidden blood in the stool and is usually conducted annually.
- Sigmoidoscopy: Similar to a colonoscopy but examines only the lower part of the colon. It is recommended every five years if used with FIT.
"Early detection through regular screenings has proven to significantly lower the mortality rate associated with colorectal cancer."
"Early detection through regular screenings has proven to significantly lower the mortality rate associated with colorectal cancer."
The effectiveness of screening cannot be understated. Regular checks can identify pre-cancerous polyps, facilitating timely intervention that can prevent the progression to colorectal cancer. Negotiating the often-confusing landscape of screening options is essential for maximizing the benefits of preventive care. Understanding one’s personal risk factors helps tailor screening plans appropriately.
Adopting a Healthy Lifestyle
Adopting a healthier lifestyle is another cornerstone of effective prevention. This encompasses physical well-being, dietary choices, and mental health, all weaving together to promote a robust defense against colorectal cancer.
- Balanced Diet: A diet low in red and processed meats, while rich in fruits, vegetables, and whole grains, is beneficial. Fiber is especially important as it aids digestion and helps maintain colon health.
- Physical Activity: Regular exercise is not just for weight management; it's linked to lower cancer risk. Aim for at least 150 minutes of moderate aerobic activity weekly. Simple changes can make a big difference:
- Weight Management: Maintaining a healthy weight reduces the overall risk of developing several types of cancer, including colorectal. Often, excess weight leads to inflammation, compounding cancer risk.
