Unfortunately, beyond a low-fat diet with lots of fresh fruits and vegetables, I really cannot make any specific diet recommendations.
There is no research data available regarding the effects of diet or dietary supplements for this particular type of cancer (for more details on general cancer prevention strategies, you can also order a copy of my book, "A Cancer Prevention Guide for the Human Race").
Sincerely,
