I found a bump right above my nipple its red and on the top it looks like its peeling off but its not. It's the size of a pimple but I don't get acne or pimples on my body so I really don't think it is a pimple,it does not itch. Its been 3 days now and I'm worried what should I do?
Also I'm 17.

It's probably a pimple or irritation around a hair follicle, or a harmless cyst. Cancer would be inside your breast.

You are 17, you will get pimples somewhere.

But no cancer is not a pimple or a bump outside.

But if you have bumps you don't know, the answer is easy, if it was cancer, caught early is normally cured.

So you make an appointment and go to your doctor for a proper exam
