I found a lump in my right breast which I originally thought was just a cyst and was sent to the breast clinic but as I’m only young (18 years old ) the doctors weren’t worried. I also had mastitis in my left breast and took antibiotics however as I don’t have children and I’m not pregnant I was a little confused and when I went to the clinic it hadn’t gone after a full course of antibiotics and was told it was just a thickening of cells however it’s very painful and is getting much harder and lumpier as the days go on. I had an ultrasound and the doctor diagnosed me with a Fibroadenoma. He said it was fine and i should be fine and come back in a couple months for a check up. However in the past few days it’s veen growing at an increasingly worrying rate. Would anyone be able to give me some advice?
