I am a 47 year old female, past medical is 4 successful pregnancies, tubal ligation, partial hysterectomy (ovaries were left), gall bladder removal. Family history on father side is very high with cancer, prominent being colon cancer. I had my first battle with hemorrhoids about a month ago. For two days now, I am experiencing a large amount of bright red blood in the toilet bowl and on the paper when I have a b.m. There is no pain. I m sure you can understand my concern and am wondering what else can cause this bright red bleeding.
