(but now I hear they don't diagnose very well??) Last couple of weeks I've had a blood
discharge from my rectum once and a while. When it happens, it's the only thing that comes out. Strange. It hasn't been on the stool, or mixed with it, or on the toilet paper or anything. Sorry for being so graphic, but I'm scared to death. I'm a mom, and two of my grandparents have had colon cancer (both over 50, and both are fine, now) I feel fine otherwise, except for some constipation.
