Hey, about a month 1/2 ago i noticed this small pea sized bally lump hard thing one morning beside my left nipple, on the edge of the areola. it had a white head which i scratched off and pus came out, but it didnt go away, it is still there, still red and still hard. I went to the doctor and they told me its an ingrown hair, but I'm really scared its cancer. I am 17. about 250 pounds, very big boned, slightly overweight, and about 5'11. i dont have much of a medical history.
