Thank you for all your comments.
I have had my first visit to the Oncologist and have a treatment plan involving hormone therapy, radiotherapy and possibly early chemotherapy. Decision about Stampede will be made next week.
As far as the rest goes, her comments were:
Diet (avoid sugar, dairy, saturated fat, meat and basically go vegetarian, organic if possible) - probably the healthy option but not sure if it affects prostate cancer. Acid -v- Alkaline ("cancer can't grow in an alkaline body") - didn't believe it as the kidney will regulate pH in the body. If you consume a lot of acid foods (https://s3.amazonaws.com/ashleylpitman/VIXI_ACID_ALK_final.pdf) then obviously not good for you.
Exercise (daily exercise routine, fast walking, sports, gym, etc) - all good for general health and fitness, some evidence that it helps with recovering from prostate cancer.
Complementary (B17 vitamin apricot kernels, CBD cannabis oil) - some evidence that pomegranate tea is good for prostate cancer, aware of apricot kernels but no experience, not aware of CBD but will look into it.
It would seem that in the UK not enough research is being done into non-drug based treatments and that the medical profession are not trained in nutritional aspects.
Be good to hear from anyone with experience of diets and especially apricot kernels and CBD.
