rectal cancer causes
what causes rectal cancer?
Mistakes in DNA can cause cells to grow out of control. Faulty cells pile up to form tumors. These cells can penetrate and destroy healthy tissue. What sets off this process isn’t always clear.
There are some inherited gene mutations that can increase risk. One of these is hereditary nonpolyposis colorectal cancer, known as Lynch syndrome. This disorder raises the risk of colon and other cancers, especially before age 50.
Another such syndrome is familial adenomatous polyposis. This rare disorder can cause polyps in the lining of the colon and rectum. Without treatment, it can raise the risk of colon or rectal cancer, especially before age 40.
Other risk factors for rectal cancer are:
- age: diagnosis usually occurs after age 50
- race: African-Americans are at higher risk than people of European descent
- personal or family history of colorectal cancer
- previous radiation treatment to the abdomen
Other conditions that may increase risk include:
- ovarian cancer
- inflammatory bowel disease
- type 2 diabetes that’s not well managed
Some lifestyle factors that may play a role in colorectal cancer are:
- diet with too few vegetables and too much red meat, particularly well-done meat
- lack of exercise
- consuming more than three alcoholic drinks a week
