Hello I noticed a small bump under my right breast about two or three weeks ago it has not gotten bigger or smaller. I have not went to the doctor at all about it. when I first noticed it it was a little sore to the touch I thought it was a zit or something as I do get a lot of them on my upper inner thigh every month I tried to pop it and mostly blood came out with every small amount of clear fluid now it sore again and haven't gotten smaller. I'm scared my grandmother died of breast cancer what should I do
