Thanks!

Thank you very much for your quick reply! I appreciate it and am relieved, although I will still talk about it with my parents following your advice. Thanks again!

The chances that what you're describing is cancer are very low. If you're worried, though, you should tell a parent that you feel something you're not sure about.

Hello,

I am only 13 years old and have noticed a long continuous lump in the left testicle. I sometimes feel it is heavier than the right one. I have significantly less hair in that testicle, feel the lumps are not necessarily hard and are located along the epididymis, and it sometimes hurts mildly. I have had this since I was about 10 if I am not mistaken and have never asked anyone. I have lately found out it could be cancer, and am extremely tense. Could it be testicular cancer? and Is sterility involved in it?

Help would be terribly appreciated.
