So around 2-3 months ago I found a hard lump in my armpit but it can only be felt when my arm is down, if i raise it it completely disappears. It’s probably around 1-1.5cm and it’s moveable. There is no pain. I obviously phone the doctors straight away and they booked me in. She felt it and said she definitely feels it, and she has sent me for a non-urgent referral to the breast clinic. I am only 19 and I am extremely worried. It is still here 3 months later. It hasn’t grown, but it seems to move less? Can anyone help me here on what to expect and if I should worry?
