So I'm only 23 years old and have no family history of Colon Cancer. I was have strange bowel symptoms which lead to a colonoscopy. During the colonoscopy they said everything was totally normal except they found one 4mm sessile polyp in the sigmoid colon which they removed completely.
They said they are sending it to pathology to see if it is adenomatous or hyperplastic. They said if it is the pre-cancerous type I'll have to get re-scoped every 5 years but if it's hyperplastic then I don't need to worry about a scope until later in life.
My questions are. Is 4mm big for a polyp? Is this pretty serious if it is the pre-cancerous type. Should i feel relived about the situation seeing as the polyp (whatever kind it is) got removed completely? Is it possible that even though the polyp was 4mm and removed all the way that I can have cancer right now? Basically, should I still be worried?
