Honestly your dr or drs need to be more aggressive in their treatment! I sought multiple opinions at 11 PSA
I first cut out sugar including very little fruit ( so I could eliminate natural sugars as well)
I restricted carbs a lot, but I did not eliminate them. I increased salads with olive oil, vinaigrette, type dressings. No sodas, no, french fries, almost no beef, or processed red meat of any kind, increased consumption of fish. Then I saw a naturopathic person and added magnesium glycinate (specifically) a super B complex, double the daily dose of vitamin C, with rose hips. Multiple vitamins, saw palmetto, iron, D3, melatonin, and two I don’t remember how to spell. I take the majority in the morning with a small breakfast. The chemo pills I take have the side effects of increasing belly fat in men or women, it’s just a side effect and so you have to eat less and exercise more. Walking is good dumbbells are good. I am still researching minerals to take and I am going to add a broccoli pill or a plankton pill I am going to continue this research on cures. No sugar seems to be the most beneficial first step
