I am 17 years old(12th grade). I have had a small lump about the size of a pea if not smaller on the left side middle of my left testicle. The thing is I have had this lump ever since I could remember, probably going back to 5th grade. I have never really worried about it, and it has always just been a small bump. Now lately I have been worried after reading all this stuff on how it could be cancer. The thing is it has not grown, and for the past 7 years if not more I have been perfectly fine and healthy. Could it be cancer or would I have noticed something by now? thanks for the help an advanced
