On my left testicle inside the sack i've felt a non painful 2 small hard lumps should i be worried?

Doctor can evaluate: A guy in his early 30's with one or two lumps on a testicle should not be ignored. His doctor should closely examine both testes and scrotum. An appendix of a testicle (a small lump near a testicle) might be a lump on the testicle. No lump growth or change in many, many years makes a lump likely non-cancerous... but new lumps are unknowns and need to be examined closely.
