I m sixteen years old and I m worried I have testicular cancer. I found something pea shaped to the side of my right testie. It seems to be attached my something. But not directly, they are close though. It doesn t hurt when squeezed, and I didn t know if something was inside of me at first so I shun a light underneath my scrotum onto it and light passed through. I read somewhere that it could just be a swelling of sperm or water. I m just worried though. I masterbate on average, daily if that has anything to do with it. Please get back to me as soon as you can. This is causing me a lot of stress.
