Is this normal?

I found a small lump in my right armpit 3 or 4 months ago. The lump is toward my back, slightly above the crease. The lump is firm, does not move around, and does not hurt. The only reason I am worried is because I notice today that it is now slightly bigger. I had a total hysterectomy 30 years ago ànd am post-menopausal. Should I just wait and keep checking every couple of weeks?

Have it checked right away.

I agree, have it checked immediately. We have to keep a close eye on possible swollen lymph nodes, etc.

Just because it's painless, doesn't mean you shouldn't get it checked out- and soon! Let us know how you get on!
