I am sorry to hear about your problem. It is good that you are keeping fit and eating well.
No guidelines have been set for treating patients with advanced prostate cancer in whom local therapy has failed. A balance between disease control and minimization of the toxicity and intolerance of the treatment is the aim. Intermittent androgen suppression may be considered by your doctor. Following may be considered by your oncologist;
1) Bisphosphonates to strengthen the bones.
2) Chemohormonal therapy;
e) Abiraterone acetate
Following dietary measures are helpful (which you must be doing):
a) Diet comprising mainly vegetables, fruits, grains, and fish, combined with restricted caloric intake and exercise. Such a diet provides multiple micronutrients packaged in their most effective form. Whole-grain bread provides fiber, iron, vitamin E, and folate.
b) Fruit juices such as pomegranate juice provide antioxidants.
Please feel free for your follow up questions.
I would be happy to assist you further, if you need any more information.
