For about the past 4-8 weeks I have been having more bowel movements than usual. I almost never feel as if my bowels are empty. If I do feel emptied out, the feeling does not last long. I have no other symptoms that I find listed for colon cancer; no blood in my stool, no especially thin stool. I am 67 years old with a family history of colon cancer. My last colonoscopy was three years ago and, at the time, my gastroenterologist said that I needn t have another for 4-5 years. I will be contacting my gastroenterologist tomorrow, but I am very worried about the possibility of cancer. Thank you
