Can spermatocele cause pain in the groin? or is it only testicular cancer?

Can cause: Most of the time spermatocele is painless, testicular tumor is also in the initial stages, you must see your doctor early stages testicular tumors are curable.Please see your doctor.

Not likely.: This does not cause pain normally. It can cause discomfort if it gets too large, and can be differentiated from the testis by shining a light as it is transparent. If this does not clarify this, ultrasound of the scrotum/testes area can do it. Testicular cancer also isn't usually painful, but is not clearly illuminated generally, and other tests, like ct scan and serum AFP and bhcg are needed.
