A couple of months ago i noticed a ***** pimple on my boob like ones i get on my face a lot, thinking nothing of it i popped it and expected it to heal on its own. When i popped it two hard stone like things came out too. It's been a while and there is still a red mark where it was. It's probably trivial but i still worry. I'm only 14 so cancer isn't likely but I'm still worried.
