Hi, Doctor, I am a 75-y.o. male in generally good health (in spite of a 60-year cigarette habit). Had a vasectomy 40 years ago. A couple of days ago, I noticed a significant (marble-sized) lump on my right testicle. I am awaiting an exam by my VA provider and expect to get any Dx/Tx needed there. Mentioned it to my son, who is 40, and he said he has several such lumps in his scrotum and was told by a urologist that it s a perfectly normal condition. Sounds a bit bizarre. Can you clarify? [NOTE: I m a retired trial lawyer who spentg 35 years defending docs in a courtroom and digging deep into relevant medical issues. I m probably ahead of the curve for a layman.] Andy
