Talk to Gynecologist on Cyst On Top Of Breast

I have noticed this cyst on top of my right breast. Its attached to the skin surface. Top right of the right breast. It doesnt move its about a pea sized and can be grabbed from the top of my skin layer. I have currently weaned my 4th child and exclusive breastfed all four. Dont have any history of cancer in my family. Recently i had swelling in the same area which had blood drainage no puss. Which i thought is body acne because i also have body acne.
