i have found a very small lump very high up on my left testicle, i have read through every website to try and find information on this topic. i turned 16 a month ago and am scared that it may be cancer but am also worried about consulting my docter. it does not cause any pain and is not on the other testicle. its only very very small its been there for about a week and a half now im just trying to decide what to do at the moment and any advise from anyone would be extremely helpfull. thank you.
