Post colonoscopy question

I had my first colonoscopy in 2001 in which a golfball size polyp was removed.  The polyp was determined to be nonmalignant.  In 2003 and 2007 I repeated the procedure with no issues.  In October (2009) I began to have blood in my stool and was not able to have a normal bowel movement.  I was scheduled for a colonoscopy in December.  I had the procedure on 07 December.  The doctor removed "part" of a polyp that was growing in the same location as the one removed in 2001.  He said the polyp was larger than the first - larger than a golf ball - but smaller than a baseball.  He said he couldn't remove the entire polyp because it was in a fold in the intestines.  He requested I make an appointment for the following week to discuss if I would need surgery.  I am currently experiencing some rectal bleeding - four days after the procedure.

As a note - my grandfather on my mothers side was 43 when he died from colon cancer... I'm 45.

My questions are:
1.  Should I be concerned that only "part" of the polyp was removed?
2.  Should I be concerned that the polyp grew to this size in less than three years?
3.  Should I be concerned the polyp was in the same location as a previous polyp?

Thanks.

Yes, you should be concerned that this polyp regrew in the same spot. But  I think they may not have gotten it all the first time.  It's obviously in a tough spot to completely remove during a scope.  Having part of it removed for now is fine, because it is what was keeping you from having a normal bowel movement, you actually had a partial bowel blockage due to the size of this polyp.  If you had suffered a total blockage you would have required emergency surgery. Polyps tend to bleed, but if you're bleeding a lot, call your GI. Since it was benign before, I assume it is again?  I would opt for surgery to be sure that it is removed in it's entirety.  On a good note, having one polyp is good, and the fact that you are proactive with your health, you will be fine. I work extensively with 5 geneticists across the country due to an heriditary bowel disease in our family.  They have now proven that a regimen of aspirin not only shrinks the polyps, but even prevents them from forming.  Speak to your doctor about this after having this one polyp removed. You won't die from colon cancer, most people have at least one polyp by 45, and should start regular scopes at 50.  You're actually ahead of the game, stay that way.  My sons colons were carpeted with thousands of polyps which was known to turn cancerous by their early 30's.  Relax, and just stay on top of your health in every way.  Take care....
