i'm sorry you're going through this but i'm glad to see you're so vigilant about your breast health. way to go! first let me say breast cancer in a 16-year-old is exceedingly rare. i want to put your mind at ease about that. the problem is likely something far less serious. it wouldn't hurt to get this situation checked out by your doctor or nurse practitioner. it could be related to hormones (because of course they fluctuate) or something else that's very simple (such as circulation issues). even if the situation clears up over the next few days i'd suggest you get this looked at. you'll feel less anxious and your doctor will get the condition into your medical history in case it occurs again. wishing you well!
i have one purple nipple. it's acts weird. i am 16. just had my period and when it stopped only one nipple became very sore and part if my armpit also. the nipple was first very pink and today it was almost purple when i woke up. it has a normal shape it's not swollen. it acts completely different from tr other nipple like sometimes it's pointy and the other isn't. i'm only worried because everywhere i research it says if only one breast/ nipple has an issue it's and issue but not if it's happening to both. btw i don't have sex?
