I'm taking anabolic steroids and i've noticed to develope gynocomastia in my right nipple today noticed painless lump in right armpit, should I worry?

I'm a 20 year old female, and have noticed a hard, painless pea-sized lump in my armpit. It's been there for two years or so now, what should I do?

Lump: What you describe does not sound to be dangerous, not anything like cancer, since it has been asymptomatic and stable for 2 years.
