8 Ways to Prevent Colon Cancer There are a few things you can do to lower your risk of colon cancer. First, eat a healthy diet that includes plenty of fruits, vegetables, and whole grains. It's also important to get enough exercise and to avoid being overweight. If you drink alcohol, do so in moderation. And if you smoke, quitting is the best way to reduce your risk of colon cancer. You should also get screening tests for colon cancer, which can find precancerous polyps so they can be removed before they turn into cancer. If you are experiencing symptoms that could be indicative of colon cancer, it is important to visit a colorectal cancer specialist for proper diagnosis and treatment. Symptoms of colon cancer can include changes in bowel habits, such as diarrhea or constipation, blood in the stool, abdominal pain, and weight loss. If you are experiencing any of these symptoms, it is important to consult with a colorectal cancer specialist to determine the cause and to receive the appropriate colon cancer treatment.
