Cancer that starts from the large intestine is called colon, and cancers that develop from the large intestine of about 15 cm closer to the anus are called rectal cancer. Cancers that affect any of these organs are also called colorectal cancer.

Most colorectal cancers develop from polyps. The exact cause of the development of precancerous colon polyps that lead to colorectal cancer is unknown. polyps; After a series of abnormalities occur in cell DNA, it can change and turn into cancer. If a polyp is found during a colonoscopy, it is usually removed. Polyps removed during a colonoscopy are then examined by a pathologist and evaluated to determine if they contain cancerous or precancerous cells.

Scans need to start on time
It is recommended that people at risk for colorectal cancer start regular screening at the age of 45, and individuals at average risk at the age of 50 at the latest. However, if there is a personal or family history of colorectal polyps, cancer, or inflammatory bowel disease, screening may need to begin before age 45. Because colorectal polyps and cancer affect both sexes, both men and women should be screened. Colorectal cancer is treated according to the stage of the cancer. Treatment options; surgery, chemotherapy and radiotherapy to be applied by an experienced team in an experienced center.
