Who will get affected by colorectal cancer?

Who is at risk colorectal cancer?

The exact causes of colorectal cancer are not known. However, studies show that certain factors increase a person's chance of developing colorectal cancer: 

Age. Colorectal cancer is more likely to occur as people get older. Most people who develop colorectal cancer are over the age of 50. However, the disease can occur at any age. 

Diet. The development of colorectal cancer seems to be associated with a diet that is high in fat and calories and low in foods with fiber, such as whole grains, fruits, and vegetables. Eating a high fiber diet helps to prevent colorectal cancer. Patients that follow Researchers are exploring how these and other dietary components play a role in the development of colorectal cancer. 

Polyps. Polyps are benign growths (not cancer) on the inner wall of the colon or rectum. They are relatively common in people over age 50. Because most colorectal cancers develop in polyps, detecting and removing these growths may be a way to prevent colorectal cancer. Familial polyposis is a rare, inherited condition in which hundreds of polyps develop in the colon and rectum. Unless this condition is treated, a person who has it is extremely likely to develop colorectal cancer. 

Personal history. A person who has already had colorectal cancer may develop colorectal cancer a second time. Also, research studies show that women with a history of ovarian, uterine, or breast cancer have a somewhat increased chance of developing colorectal cancer. 

Family history. Close relatives (parents, siblings, or children) of a person who has had colorectal cancer are somewhat more likely to develop this type of cancer themselves, especially if the relative developed the cancer at a young age. If many family members have had colorectal cancer, the chances increase even more. 

Ulcerative colitis. Ulcerative colitis is a condition in which the lining of the colon becomes inflamed. People who have ulcerative colitis are more likely to develop colorectal cancer.
