What causes colorectal cancer?

There is no exact cause for colorectal cancer. However, it is known that cells of the colon and rectum somehow develop changes (mutations) in their DNA, which causes abnormal growth and potential to spread to other body tissues. The erratic production of these mutated cells eventually form clumps of cells called adenomatous polyps. In some cases, the cause of colorectal cancer is due to its many risk factors. A small number of colorectal cancer cases are linked to underlying genetic disorders, such as adenomatous polyposis or Lynch syndromeOther medical conditions that increase risk for colorectal cancer include chronic inflammatory diseases, such as ulcerative colitis and Crohn’s disease. It is important to treat these conditions in order to avoid them advancing to cancer of the colon and/or rectum. Untreated colorectal cancer can also metastasize to nearby organs and blood vessels, causing potentially life-threatening complications.
