Breast lump from finasteride, I think

I took finasteride for a year and developed gyno from it. When i noticed the lump in my left chest i stopped taking it. However, what happened was weird. After stopping finasteride for like more than a month, the hard lump in my left chest disappeared but at the same time a hard lump appeared in my right chest. My left nipple is still swollen and big though. But on pressing it i dont feel a lump.

I want to know whether this gyno will go back on its own or if surgery is must. I never had gyno before and i’m 100% sure its from finasteride.

If the lump remains, you should see a doctor. Breast cancer is very rare in men, but it does happen.
