I noticed the dark spot on my left breast last week. It doesn't look good to me. Does anyone have any ideas. I just cried today when I looked at it, I am so worried that it will spread. I don't want to phone doc till I am sure there is an issue. I had to phone last week about the other spot on my right breast. She said to put antiseptic on and wait and see. Trouble is that I think there is a stitch hanging out. I pulled at it, but it won't budge. I am really anxious but I dont know if I am just being silly.
