Question: I am currently 15 weeks pregnant with my second child and kind of concerned about colon cancer. I have had some constipation with this pregnancy which has resulted in an external hemorrhoid. On the day that the hemorrhoid developed, I was pretty constipated and passed a large, hard stool. I noticed a bit of bright red blood on the outside of the stool. Later that day when I sat on the toilet to empty my bladder, I noticed that the area on the outside of my anus felt sore...I also noticed some more fresh blood that seemed to be coming from the hemorrhoid. I have had no bleeding since and it has been over a week. The hemorrhoid is still present, but gradually shrinking and is no longer causing discomfort. What concerns me is a strange feeling in my lower left abdomen. I only notice it when I lift my left leg as in to step over something or to climb into bed. It almost feels like a pulling or maybe a slight fullness...never painful and not present every time I lift my leg. I mind is racing because I have had rectal bleeding before...about two years ago and off and on during my pregnancy with my 17 month old daughter. I only noticed bleeding when there was pain (like with a hemorrhoid or a fissure) while passing stool. I can remember no recent bleeding up until last week's event and there has been none since then. My question is, could this strange sensation in my lower left abdomen that is felt only upon certain movements, be from colon cancer? I am 24 years old, which I know is young, but I also know that it doesn't mean something like this can't happen to me. I have had this sensation in my abdomen before I was pregnant and it went away on it's own, and now it is back. I am feeling fine otherwise. No morning sickness or anything like that. Just tired, constipated and gassy...all of these symptoms seem to be dissipating now that I am in the 2nd trimester. My bowel movements are very regular. I will also add that I had a c-section with my daughter.
