Radiation
Radiation exposure to the spine, pelvis, or abdomen, when you were a child, would increase the risk of colon cancer. That is why it is important to have a regular screen for the disease every year. In addition, those people who receive radiation therapy for treating testicular and prostate cancer would have a high rate of rectal and colon cancer. Make sure to discuss carefully with your doctor before starting any treatment for your existing tumor. [10]
