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?

Yes: Yes, you should worry. There are very few reasons for a teenager to take anabolic steroids. Actually none that i can think of. Sure, maybe testosterone for medical purposes such as sexual maturation but this is always done under close supervision and it's never referred to as :anabolic steroids:. So yes, you need to be worried. Talk to doc who's prescribing your steroids . .

Yes you should: Anabolic steroids are very detrimental to your body longterm and you should stop taking them. They have very dangerous side effects, the least of which is development of gynecomastia. The breast tissue development is usually not reversible when the drug is stopped. I'm in orlando and perform a lot of gynecomastia surgery. Consider checking out the forum on gynecomastia.Org.

More to come: Sounds like you are just getting started with side effects of anabolic steroids, next will come shrunken testicles, enlarged prostate, erectile dysfunction, reduced sperm count, severe acne, high blood pressure and strokes Whether to worry about having all these added health problems is appropriate is up to you.
