Re: some sort of growth

This sounds a lot more like a cyst than a tumor. That is to fast of a growth for a testicular tumor and the rest does not sound like a tumor either.

He can either find another doctor to drain it if it is a cyst. Or try herbs for the lymphatic system, which are great for cysts. Chickweed is my first choice followed by red root. Warm compresses with Epsom salts (magnesium sulfate) may help as well.
