[|AI|]  Hi, Thanks for writing in. Sorry to know about your father. Unfortunately stage 4 cancer is a difficult condition to treat, and you might be aware of his condition. Chemotherapy is usually aggressive when dealing with the cancer. Pain relief is also required to keep him comfortable. Chemotherapy and radiation therapy are recommended for treatment of stage 4 cancer prostate. If he has taken chemotherapy and radiation therapy and his general condition is satisfactory then giving another chemotherapy is acceptable. This is to extend his survival and if he can tolerate it then there is nothing wrong. Since his cancer has spread to bones therefore he might have severe pain. Alternative pain relief measures like acupuncture, steroid injection and nerve blocks are available, and he might benefit from these techniques. Strong pain relief medicines can also be given. Please do not worry.
