hi Dr. Grief I am a 70 yr. old male, how often should I be having a colonoscopy, I had a pre cancerous polyp removed about 12 yrs ago and have had three colonoscopys since, I am scheduled for another in 2016, all procedures have been negative since original 12 yrs. ago.jim
Ok, do u ave any family history. U have to undergo colonoscopy as it is very essential ans screening method of detecting cancer at precancerous stage. And u have a history in the past. So I will suggest u to undergo colonoscopy.
