I have cancer too. Diagnosed 3/06. I began the Johanna Budwig Protocol shortly after my diagnosis. In 15 months my tumor has shrunk by almost 60%. Dr. Budwig, a brilliant woman, won a Nobel Prize for her work.
Although, I do not have the same cancer as your husband I think you'll find testimonials in the following links regarding his particular kind.
The basis of the program involves consuming healing omega 3 oils ( from flax seeds and the combination of cottage cheese and flax oil) and eliminating certain foods from the diet.
My experience has made me a big believer and I know there are many others who feel the same way.
You can find some information at the following sites.

( This is a great resource. Join the group and read the files.)
I would be glad to try and answer any questions you may have.
If you'd like to talk on the phone that would be fine.
This has been a blessing in my life that I have to share.
May God bless you, your husband and family.
Mike
