Colorectal Cancer Screening
Colorectal cancer screening tests detect cancerous cells and growths, or polyps, that may become cancerous on the inside wall of the colon. Not everyone needs to be tested for colon cancer, though; the need depends on individual risk level. Three major factors influence the risk for colon cancer:
- Age 50 or older
- A family or personal history of colorectal cancer or precancerous polyps
- A personal history of inflammatory bowel disease
