What is bilateral testicular cancer?
Bilateral testicular cancer means that both testicles have cancer at the same time. From what I've read, this is pretty rare. Usually the cancer starts only in one testicle, which is treated with surgery called an orchiectomy (and possibly radiation and/or chemotherapy).
The operation that's done for bilateral testicular cancer, to remove two cancerous testicles, is called a bilateral orchiectomy.
