What is a painless lump just inside anus? had colonoscopy 3 yrs ago. had only internal hemorrhoids. am 56 yrs old.

Could be....: Thrombosed hemorrhoid, small infection or abscess, anal mass such as skin cancer or anal cancer. I would get it checked out if it starts causing pain or doesn't resolve quickly. I'd be happy to see you, but im in memorial city, sugar land, or katy.

Hemorrhoids: It can be hemorrhoids but also may be a polyp or rectal lesion. You need to be examined.
