Who is at risk for colorectal cancer?

Every one of us is at risk for colorectal cancer. Although the exact cause for the development of precancerous colon polyps that lead to colorectal cancer is not known, there are some factors that increase a person's risk of developing colorectal polyps and cancer. These risk factors include:

• Age: The risk of developing colorectal polyps and cancer increases as we age. Colorectal cancer is more common in people over the age of 50, however, younger adults can also develop colorectal cancer.
• Other medical conditions: Medical conditions (type 2 diabetes, previous history of cancer, history of inflammatory bowel disease) and inherited conditions (Lynch syndrome, familial adenomatous polyposis) can increase your chances of developing colorectal cancer.
• Lifestyle factors: You may be at increased risk for developing colorectal cancer if you drink alcohol, use tobacco, don't get enough exercise, and/or if you are overweight. Smoking increases the risk of precancerous polyps and colorectal cancer. A diet high in fat and calories and low in fiber, fruits and vegetables has been linked to a greater risk of developing colorectal cancer. Many lifestyle factors that increase the risk of colorectal cancer can be modified to lessen that risk.
