The prognosis for dogs with treated testicular cancer is usually very good. The low rate of metastasis makes surgical neutering
very successful and curative in most dogs. Dogs that develop hyperestrogenism from Sertoli cell tumors will often have a regression
of signs, once the tumor has been removed. In severe hyperestrogenism that results in anemia, some animals may require transfusions
and more aggressive treatment with erythropoietin therapy. The prognosis for testicular tumors that have metastasized is more
guarded and the outcome varies widely depending on location, type and treatment.
Testicular cancer is easily prevented, and with good neutering policies could be virtually eliminated from the dog population.
Neutering in young dogs prevents aggression, roaming, urine marking and a variety of other unwanted male behaviors. The surgery
is safe and relatively inexpensive, and in the long run saves the owner money. Dogs that are used for breeding can be castrated
when they are no longer used for breeding. Dogs that are cryptorchid should always be castrated, and the owner should insist
that both testicles be removed.
Since cryptorchidism is considered to be an inherited trait, cryptorchid dogs should never be used for breeding purposes.
Because the retained testicle is 13 times more likely to develop a tumor, it should always be removed.
