Hello.. I am 21 y.o. female, 5'3", 190 lbs. A few days ago, I noticed a red bump on my left breast... resembling a mosquito bite. I did not pay much attention to it and about an hour ago, before I got in the shower, I started messing with it and I squeezed it and a mixture of runny pus and blood came out. It is now looking inflamed and bruised up a bit from poking at it so much. Should i be worried about this? Also, I think i may have a skin condition because my breasts are covered in these little whitehead looking things with small feathery hairs in them.. kinda gross, sorry. :/ if I squeeze them, i can usually get pus out of them. I'm worried this might be breast cancer, please help!!
