I tried to send a messege to tell you my husband has the same thing in one leg and one testi and he discovered it is cancer.
the testi must b e removed and radiotheraby is the answer.
ct scan must be done after the surgery to be sure that it is not spreading. do not delay do it right away before it is too late
you can search the net for testical tumer and you will find a lot of information about it and if you are not having babies yet do not forget to save some sperm in the sperm bank for the future.
good luck
Just a quick note to say hi!
