Colon cancer is cancer of the colon, or large intestine. If the cancer affects the last few inches of your colon, closest to the anus, it is considered rectal cancer. Colon cancer often begins with the development of non-cancerous (benign) clumps of cells known as adenomatous polyps, which are usually without symptoms. Therefore, getting checked is important to your health. It is recommended that after age 50 you must get check regularly for colon cancer.
It can be difficult to sort through all the information your pathologist (who will help make the diagnosis of colon/colorectal cancer) will share in his/her report, but that's where you should depend on your doctors, especially your oncologist, to help you understand what your next steps should be for treatment and beyond. Ask questions if you do not understand all the information. Staying informed will be vital to your continued good health.
