I noticed, quite a while ago now, that down on my left testicle there seems to be a lumpy mass. However, on closer inspection they seem to be tubes of some sort, blue, and not actually attached to the testicle but to the tubes above it. They hang down so if my testicle was clock they are between 12 and 6. Is there a chance they could be veins or tubes of some other kind, or could they be cancerous? I am 15 and for some reason dont fancy going to the doctors as i am of a very nervous/self concious person. Any help would be appreciated as this is making me feel quite worried inside my head and i find any time my brain isnt engaged i want to go and check again and again and again.

Forgot to add, the tubes above my left testicle seem to be larger and more in number, whether this helps i do not know, i thought it may be variacose veins or whatever but im not really sure so..
