Colon Cancer Is Common

Colon cancer is common. Current screening guidelines, which were recently updated, recommend screening of asymptomatic people starting at age 45. These recommendations do not mean that people in their 20s and 30s cannot get colon cancer. Forecasters have predicted that in 2023 almost 20,000 colon cancer diagnoses and 3,750 colon cancer deaths will occur in people under 50 years of age. Almost all these deaths are preventable if the cancer is diagnosed early. This is the reason why care givers now recommend that young people, even college students, talk to their doctors about any suspicious symptoms such as constipation, rectal bleeding, or sudden changes in bowel habits.

The reason for this rise in colon cancer in young people is not yet known. Certain behaviors and factors such as a sedentary lifestyle, being overweight, smoking, alcohol use, low fiber high fat diet, and diets high in processed meats have all been associated with colon cancer. One wonders what sitting in front of a computer all day, either working or playing videos or video games, does to one’s colon cancer risk, especially if that occurred when people were in their teens and twenties.

The ultimate question is, “what can be

done to avoid colon cancer?” Although not all colon cancer can be avoided, taking some simple lifestyle altering steps may lessen your chance of developing colon cancer. For example, if you smoke, stop! And this includes e-cigarettes. Drink alcohol responsibly. No more than two drinks a day for men and one for women. Exercise! If you are overweight, lose weight. Overweight people have a much higher risk of both developing and dying from colon cancer. Watch your diet and consume adequate fiber. Finally, make sure that you undergo colon cancer screening, by whatever method is comfortable and readily available to you.
