I'm sorry to hear about this after just reading your other post. I really hope the chemo helps and sending you well wishes.
I did similar research in to natural medicine when my dad was diagnosed a few years ago and a few common themes I found was what you mentioned to give the body what it needs to fight it. This culminated in the common theme of having a diet that makes the pH of the body more alkaline as according to what I was reading, the research generally concluded that cancer cells can't survive in an alkaline environment.
The cells thrive in acidic environment which is caused by eating the things you mentioned.
I didn't go much further regarding the effects of exercise or additional factors but that was something I found.
Take care
Thanks! At this time we are looking at everything
