Hello, i have found a small lump on my anus, it seems more internal than external, it is hard to touch and painful and when i wipe there is a little blood, the tip of the lump is part black too but other than that, flesh coloured. i am only 20 years old, female and my mother has been having regular doctors visits for possible colon cancer, which is why I m concerned. Any advice or thoughts on what it could be would be grateful! thanks!
