I’m a 24 year old woman. I got a lump checked (ultrasound) about a month ago. The dr said it was for sure a mass/solid not a cyst. It’s hard and does not move. In about a month it’s grown about 1-3 cm only but it’s a noticeable difference. I have an appointment with a surgeon in about 4 days. Is that something of concern or can Fibroadenomas or other solid things grow other than cancer?
