I think they are all good ideas. There are many alternatives to western medicine for all ailments, whether they will work is another thing altogether. I think I have read somewhere about Amaroli curing cancer, not sure though, also hydrogen peroxide may be another one to look into, but Amaroli's probably better. Also have you looked into Ayurveda? Also Chinese healing? I came across this about a year ago don't know if it is bogus or not?

http://netowne.com/alt-healing/oriental/hospital.htm . Also there is a book by Yogananda Scientific healing affirmations, it's a nice read, quite cheap, may help.
Additionally if he is that way inclined he may benefit from some self inquiry reading. Also it's not precisely self inquiry but in Eckhart Tolle's the power of now (which may benefit him, being simple and accessible to people from all walks of life, not necessarily spiritual), Eckhart highlights how terminal illness can bring people very close to the truth of themselves/the self/the one, their true nature. I have also read other Advaitists etc, Mooji, Gangaji speak of this. It may be his time, awakening can happen through facing death.
Other than this don't know what to say, regular AYP practice is always good.
Hope this helps
Blessings
Love
