Hi Guerrero, it could be a tiny cyst, it could be a tiny wen/benign tumor, infection, if you have hairs around there it could be an impacted hair, best to get it checked the next time you see the doctor or just make an appt to get it checked so you don't worry about it anymore.
Hi,
This could be a little cyst,a boil or a pimple,which can appear on your breast as on any other part on your body.It can occur for various reasons, from pores clogged with dead skin and oil, to bacterial infection and even from stress and hormones.
The chances that this is cancer are very doubtful,but any lump found in or on the breast,needs to be seen by a doctor or a dermatologist for evaluation.This condition might need antibiotics.
Take care..
