my dad has lung cancer...terrible sweats

hi, my father was diagnosed with asbestos last year. he is doing wonderful on a cancer diet. no Sugar and everything is vegetables, fish, almonds, all natural turkey breast. he has been following the diet for six months. he also sees a homeopathic doctor. he is taken essaic tea, mushrooms and cellular defense for about four months. he has had many chemotherapy treatments, along with radiation treatments over the past year, but his treatments ended about five months ago.

my question is he started to profusely sweat wear his bed gets totally soaked and he needs to change his clothes constantly. i feel his head and it feels like he just got out of a shower.

can anyone help me with this?

and has anyone heard of b-17. i was told by a cancer survivor that this helped her drastically. any information would be greatly appreciated.

thanks...i want my dad to live!!!
