Genetic testing for colon cancer is recommended for individuals with a personal or family history of colon cancer, particularly if the cancer was diagnosed at a young age or if there are multiple cases in the family. It is also advised for those with known genetic syndromes that increase colon cancer risk, such as Lynch syndrome or familial adenomatous polyposis. Additionally, individuals with certain precancerous conditions, like adenomatous polyps, might benefit from genetic testing for colon cancer to guide surveillance and preventive measures. Consulting with a genetic counselor can help determine if genetic testing for colon cancer is appropriate based on personal risk factors.
