Colorectal cancer is the third most common cancer worldwide and the second leading cause of cancer-related deaths. It typically develops from polyps in the colon or rectum that undergo dysplasia and progress into adenocarcinoma through the adenoma-carcinoma sequence.
Many lifestyle-related factors have been linked to colorectal cancer. In fact, more than half of all colorectal cancer cases are associated with modifiable risk factors.
Modifiable Risk Factors for Colorectal Cancer
Here are several habits and conditions that can increase the risk of colorectal cancer but can be mitigated through a healthy lifestyle:
Obesity
Excess body weight—particularly in men—is associated with a higher risk of colorectal cancer. Maintaining an ideal body weight is important in lowering this risk.Type 2 Diabetes Mellitus
Individuals with type 2 diabetes are at increased risk due to factors such as insulin resistance and chronic inflammation. This risk often overlaps with obesity and physical inactivity.Dietary Patterns
A high intake of red meats (beef, lamb, pork) and processed meats (sausages, nuggets, smoked meats) has been linked to an increased risk of colorectal cancer. In contrast, a diet rich in fiber, fruits, and vegetables can help reduce this risk.Smoking
Long-term smoking not only damages the lungs but also increases the likelihood of developing colon polyps, which can progress into cancer.Alcohol Consumption
Even light to moderate alcohol intake has been shown to elevate colorectal cancer risk. Avoiding alcohol is recommended to lower the risk.
Non-Modifiable Risk Factors for Colorectal Cancer
Some risk factors cannot be changed but should still be monitored carefully. Early screening is highly recommended if you fall into any of the following categories:
Age
The risk of colorectal cancer increases with age, with most cases occurring in individuals over the age of 50.Race and Ethnicity
African Americans and individuals of Eastern European Jewish descent (Ashkenazi Jews) have the highest rates of colorectal cancer.Family History
A family history of colorectal cancer significantly increases an individual’s risk of developing the disease.
A Healthy Lifestyle Makes a Difference
Healthy lifestyle habits are known to improve overall health and well-being, while unhealthy habits can lead to various health issues. Adopting a balanced diet rich in fruits, vegetables, and fiber—and limiting red meat, processed foods, and sugary beverages—can help prevent colorectal cancer (CRC). When combined with regular physical activity, these changes can significantly lower your CRC risk.
