Under my left testicle there is this painless, soft mass which seems to be attached to the tesicle and seems to go down a bit...(I can't feel the same thing under my right testicle)...is this 'mass' something normal or is it something like Testicular Cancer??(I am 14 yrs old)
What i felt might be the Epididymis though i feel that it is bigger around the left testicle than around the right testicle.

i would have it looked at by a doctor. That's what my b/f had before he found out he had TC. don't worry yet until you know for sure, but definitely have it checked if you have doubts.
