PSA is an indirect indicator for prostate cancer (and not a particularly good one!)
Reducing PSA could simply give a misleading impression that the cancer is slowing.
As for diet to combat cancer, there is virtually no evidence of anything having an effect.
Sure a healthy diet can do no harm, and may help the body to fight the cancer. But, as we know, the body can't fight the cancer, so the benefits are probably small. But a healthy diet when living with cancer is still a good thing, as anyone with cancer is always at risk of other diseases (including further cancer), and a healthy diet is a good way to promote your body's preventative activity.
Lest we forget, the "Five A Day" was introduced to help reduce cancer - it didn't, but had a significant effect on heart disease statistics.
Cutting back on red meat and dairy will definitely reduce the risks of certain other cancers, particularly bowel cancer, but there's zero evidence that it has any effect on an existing cancer.
Finally, some diets talk about 'starving the cancer' - this is frankly insane. Cancer is part of your body, and has almost identical nutritional needs. Starve the cancer and you starve yourself.
Finally, as an eminent oncologist once said,' if you go on one of these fad diets, it won't help your cancer, but it will stop you becoming depressed. If you're up at seven every morning to slice vegetables all day, you haven't got time to be depressed.'
Not smoking, of course, cuts the risk of many cancers (Including PCa). But stopping smoking doesn't make the cancer go away.
Cutting out bacon can also reduce the risk of getting some cancers, but is there life without bacon? No.
