Summary of colon cancer screening
Colon cancer is preventable and curable. Colon cancer is preventable by removing precancerous colon polyps, and it is curable if early cancer is surgically removed before cancer spreads to other parts of the body. Therefore, if screening and surveillance programs were practiced universally, there would be a major reduction in the incidence and mortality of colorectal cancer.
Ongoing genetic research will help doctors better understand the genetic basis of colorectal cancer formation. Genetic blood tests and tests for premalignant cells in stool may also have a role in colorectal cancer screening. Regardless of what new screening methods become available, you should remember to discuss colon cancer screening and/or surveillance as it relates to your situation.
