Hi,
I am a 20 year old male with a lump under my left breast. Not very large. It seems like the nipple retracts, but no discharge. It has been there for maybe 6 months, but the last month is when it has really started hurting. Even when sleeping on my left side, the pain can be very irritating. I do workout on a constant basis and have recently lost some weight. I have read up on Gynecomastia, but do not have insurance right now to see a doctor. I know breast cancer is rare at my age, but it is still possible. Any thoughts?
