Your risk of colorectal cancer is higher if you've already had rectal cancer, colon cancer or adenomatous polyps.

A personal history of colorectal cancer or polyps.

People of African ancestry born in the United States have a greater risk of colorectal cancer than do people of European ancestry. The rates of colorectal cancer in people younger than 50 have been increasing, but doctors aren't sure why. Colorectal cancer can be diagnosed at any age, but most people with this type of cancer are older than 50. Risk factorsįactors that may increase the risk of rectal cancer are the same as those that increase the risk of colon cancer. If you're concerned about your family history of colon cancer, talk to your doctor about whether your family history suggests you have a risk of these conditions. Genetic testing can detect these and other, rarer inherited colorectal cancer syndromes. People with untreated FAP have a significantly increased risk of developing colon or rectal cancer before age 40. FAP is a rare disorder that causes thousands of polyps in the lining of your colon and rectum. People with Lynch syndrome tend to develop colon cancer before age 50. Lynch syndrome, also known as hereditary nonpolyposis colorectal cancer (HNPCC), increases the risk of colon cancer and other cancers. Two well-defined genetic colorectal cancer syndromes are: Some genes linked to colorectal cancer increase the risk of developing the disease, but they don't make it inevitable. These mutations are involved in only a small percentage of rectal cancers. In some families, gene mutations passed from parents to children increase the risk of colorectal cancer. Inherited gene mutations that increase the risk of colon and rectal cancer And cancerous cells can break away and travel (metastasize) to other parts of the body.įor most rectal cancers, it's not clear what causes the mutations that cause the cancer to form. With time, the cancer cells can grow to invade and destroy healthy tissue nearby. The changes tell the cells to grow uncontrollably and to continue living after healthy cells would die. A cell's DNA contains the instructions that tell a cell what to do. Rectal cancer begins when healthy cells in the rectum develop changes (mutations) in their DNA.
