I have had a lump on the anus for about two months now, but never thought about it. After another week I noticed there was blood coming from my anus which got me a little worried but due to me being a bit scared to talk to anyone about again I left it. It is now starting to hurt (only a little, feels like a pulsing.) and I have just noticed it has now got bigger now, about twice as big and is bleeding more regularly. I really don't want to visit the doctor unless I really need to due to myself being really embarrassed. I am 17 and don't want to tell my parents until I need to. Please help I am getting very worried now as I have just read that blood passing through the anal and lumps could be cancer. Please please please help!!!
