My doctors have been like that too. I have to pull their teeth when I want some sort of screening done or want to see a specialist, but because I'm relatively fit, healthy, with no family history of anything "bad", they say my risk of things is low. I don't care. I just want peace of mind. Cost isn't even an issue, I would be willing to pay a decent sum to get regular screenings so I'm not blindsided with some stage 4 diagnosis down the road.

Be careful with this, or at least scaring/stressing yourself with this. Fresh (bright red) blood in stool is 95% of the time hemorrhoids. Most colon cancers will present with old (very dark red, or black) blood in stool.
