Hi, I have a small pea sized lump on my anus hole, it isn t painful and I m not bleeding or having any other symptoms. But I ve read up and people on the Internet have said it s just a hemorrhoid but that they are also very similar symptoms to cancer. Should I be worrying about this? It s been there for 2 or 3 weeks now with no viable change and i obviously am too embarrassed to go to the doctors about this. But I will if it is necessary. I just thought this would be the easiest thing to do before I book in.
