Thanks again for your interesting insights. However, please do not be concerned about how I read certain sites like Mercola because I'm very well aware of the financial interests involved, and take everything with a pinch of salt, or perhaps I should say a sip of soy.
I only brought up Mercola's opinion of soy because you said you were consuming it. Maybe you were not aware of the negative opinions about soy products. There seems to be conflicting evidence on the merits ot otherwise of soy so I don't know what to believe.
I'm a Brit who's lived in Thailand for the last 18 years, married to a Thai with a 12-year old daughter. My wife cooks Thai food for me most days, but as you say, diet changes later in life are no guarantee of progress of PCa.
about my choice of treatment, I decided on hormone therapy after reading several books with differing opinions and scouring the Internet. Of course my urologist suggested a RP, and when I asked for other options he referred me to a radiation oncologist who recommended high dose brachytherapy with external radiation. I travelled to Singapore to see Dr Steven Tucker who was involved with the ASCO presentation I referred to previously, and after a long discussion decided on Intermittent Triple Androgen Blockade Therapy lasting one year. "Watchful Waiting" was not an option because of the high PSA. I figured I could go back to other treatments if TAB was not successful or there were undesirable side effects, but there's no going back with a RP, RT, or Bracky.
The urologist had tried a course of anti-biotics to lower the PSA level, and was reluctant to recommend a biopsy because of the risks involved, particularly the 5% risk of infection, but since the PSA remained stubbonly high we eventually agreed to a biopsy which turned out to be positive. I sent the slides to Prof Jonathan Epstein at Johns Hopkins for a second opinion.
Johanna Budwig mixed flax seed oil with "quark" which is something similar to cottage cheese or yoghurt sold in Germany. She said that flax seed oil on its own is harmful. One of her books is available through Amazon at this link . . .
As I say, I have no idea if Budwig is a quack or not, but many of the things she recommended 50 years ago are now becoming mainstream like the importance of unsaturated fats, avoiding processed food, sugar, eating a mainly organic vegetarian diet, sun baths, avoiding stress, etc. Oh yes, a glass of wine is allowed !!
All the best,
