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.
