Am i too young to have colon cancer screening at 40 if my parent had it then?

Had screening or CA?: If parent had colon cancer at age 40, you can start screening at age 30. Consider genetic testing of parent's cancer, as well as personal genetic testing. If you mean parent got screened at age 40 (and no cancer or polyp seen), if no other risk factors, you could likely wait until age 50 (average risk group). Find out others in family, as well as other ca including breast, ovarian, kidney. C md.

Not too young: Patients with family history of colon cancer, depending on the genes involved, can get colon cancer at an age even younger than 40. Your doctor can better determine if screening with colonoscopy is warranted.
