The Journal of the National Cancer Institute published in February that colorectal cancer in young adults has risen dramatically in generations born after 1950. Those currently between the ages of 18-27 have 2 times the risk of developing colon cancer and 4 times the risk of developing rectal cancer than people born in the 1950s when they were between those ages.
Colorectal cancer develops in the colon or rectum and can be referred to as either colon cancer or rectal cancer. Most begin with a polyp appearing on the inner lining of the rectum. Polyps are more common in people aged 50 or above. Read our blog to learn more about the cause of colon polyps.

Scientists and researchers aren’t exactly sure of a specific reason, but some studies suggest factors like:
Advances in early colorectal cancer detection could also help explain why more of these cases are being found in younger people. Researchers continue to work towards finding other contributing factors for developing colon cancer.

Talking to your doctor about getting screened for colon cancer is arguably the most effective way you can reduce your risk.
