My father was diagnosed with malignant prostate cancer in two
quadrants and no metastases about two years ago. I convinced him to stop the treatments he was put on, and to avoid chemo and surgery.
I told him to take in supplements which contained zinc, saw palmetto extract, pumpkin seed extract; take vitamin E and selenium supplements or from food; take beta carotene and lycopene supplements or from food; increase protein intake; decrease high glycemic carb intake; increase vitamin D intake (from diet or from sunlight).
I told him to eat seeds of fruits (laetrile). He followed my advice as much as he could.
Now, his PSA levels are down to normal. I don't really know which
worked, or maybe all of them worked.
