This sounds like a blood blister, or some other skin-type issue. If it persists longer than a month or so - or certainly if it gets worse and spreads - you'd want to see a doctor, just to find out what it is, and whether it needs treatment. But I wouldn't worry about breast cancer, OK? At your age, your chance of having breast cancer is less than 1 in a million; and what you describe isn't a breast cancer symptom. Kudos to you, though, for being aware of breast changes at your young age; it's definitely good practice for when you're older. Take care- PJH
I have several spots like that on various parts of my body. The dermatologist checked them out, and mine are harmless. I'm guessing that your spot is a harmless skin issue too. The next time you are at the doctor, have him or her look at it. If the spot starts growing, see a doctor. It could be a skin problem that needs treatment. It's not likely, but it could be the start of an infection. If it starts to hurt or swell, you would want to see a doctor right away. In the meantime, why don't you show the spot to your mom or school nurse. She would be able to tell if this is a situation that needs a doctor's attention. You don't need to worry that this is breast cancer.
