Alright, so I'm a 15 year old male, and I'm extremely worried about my condition. Initially, a while back, I noticed a small <span style = 'background-color: #dae8f4'>lump</span> on
my right testicle. Then just recently, I noticed that my right testicle is now swollen, and has gotten a little bigger than my left one. And then noticing a large vein. I think it's my right vas deferens
and I'm not sure, but I was worried because it might be some kind of fatal disease and as a 15 year old boy, I can't tell my parents.
