Are You at Risk for Colorectal Cancer? Key Factors to Know
Published: Dec 13, 2023
Colorectal cancer doesn't discriminate, but certain factors can increase your chances of developing this disease. Knowing your risk factors can help you take proactive steps for prevention and early detection.
Contents
Age and Family History
Age is the most significant risk factor for colorectal cancer, with risk increasing after age 50. Having a close relative with colorectal cancer or advanced polyps roughly doubles your risk. If you have a family history of Lynch syndrome or familial adenomatous polyposis, your risk is even higher. These genetic conditions can cause colorectal cancer to develop at a younger age.
Lifestyle Factors
Several lifestyle factors can influence your colorectal cancer risk. Obesity, physical inactivity, and diets high in red and processed meats are associated with increased risk. Heavy alcohol consumption and smoking also raise the likelihood of developing colorectal cancer. On the other hand, regular physical activity and a diet rich in fruits, vegetables, and whole grains may help reduce risk.
Medical Conditions
Certain medical conditions are linked to higher colorectal cancer risk. These include inflammatory bowel diseases like Crohn's disease and ulcerative colitis, especially if you've had them for many years. Type 2 diabetes is also associated with an increased risk of colorectal cancer. Having a history of colorectal polyps, particularly advanced adenomas, raises your risk of developing cancer in the future.
