Would you need to have your testicles removed if there was a lump there?

Not necessarily: Not necessarily. It depends on the cause. You need to get it checked out.

No: One has to remove the testis only if there is a cancer proven by biopsy. When a patient has a lump in the testis , we do few special blood tests and explore the testis through a small incision in the groin and do a biopsy with frozen section that gives us the diagnosis of cancer right on the spot and then only we remove the testis.
