Hi, Thanks for writing in. Testicular is one of the common cancers in men after lung cancer and bowel cancer. This requires early detection and treatment for better survival and quality of life of the patient. Having a testis removed because of disease is much favored over imminent poor survival if the condition is not treated. He might require psychological counseling to make him understand the seriousness of his condition. Most patients lead normal life with good survival if a surgical removal of the affected testes is done. Radiation and chemotherapy might also help depending on the type of cancer he is having in the testis. Close follow up is required for some months. He might choose to have a testicular prosthesis in place to feel like a normal man. Avoiding or delaying treatment is to be avoided because his life is more important. Please do not worry.
