My sister died of this, she was in her fifths, I'd like to know what signs to look for, I'm 73 and have a lot of atomic problems, I've had a gastrol bleed for over 15 years now and still have them, they usually last for 2 to 7 days, and I always have blood in my Stoll so every time I get dierria I rune my clothes. She was my older half sister at the time, her and my half brother both died from cancer. I've services colon cancer back in 96, they got it in time before it could speed, but every time I'm tested I have more polips. My doctors don't seem to be concerned, but I am.
