I am a cancer surviver. I had fallopian tube cancer and am still on a severe regimen. I have done a lot of research.
I recommend strongly these websites: http://www.cancertutor.com/index.html http://www.drkelleycancerprogram.com
Although I have read many books on cancer the most useful ones in term of what to do were:
Anne E Frahm - A Cancer Battle Plan
Dr. Donald Kelly - Cancer - Curing the Incurable
Edward Griffin - A World Without Cancer.
Anne Frahm had breast cancer. Her book lays out exactly what to do.
I have found most cancer survivers don't follow just one program but integrate several and they don't stop researching.
The best to your wife. Cancer is beatable.
