Testicular cancer and its female equivalent ovarian cancer are caused by loss conflicts. Usually a person has lost a loved one, a child, a parent, friend or sibling. It is believed by some that viruses cause these cancers but viruses are actually only present on embryonic epidermal tissues as part of the healing process. Saying that microbs cause cancer is like saying rain causes the sky to get cloudy.
Having worked with these cancers successfully, I see no need for chemo, radiation, or other meds. Surgery may be required with the cases of massive tumors. Antibiotics may be required in the resultant infections during the healing phase.
As for the other conditions you mention, hydrocele is caused by a perceived attack conflict on the testicles. The swelling serves to protect them. Some of the other conditions may have to do with conflicts of feeling sexually soiled or used. Sexual guilt is also often involved.
Once these conflicts are resolved the body naturally heals.
