My friends has just called me in tears saying her DP has for the 3rd time (?) in a year had a lot of rectal bleeding when he does a poo but he refuses to see GP or go hospital. Now I believe its something bad but don't want to say anything to further upset her but wondered what I can found out here?
So he's 50, smokes 20 pack a day (has done most his life), eats a fairly varied diet, eats fruit just not much veg...and is active (ie heavy lifting at work)
What's the suspected diagnosis?
