If chemo is being used then high antioxidants such as Vitamin C (Sodium Ascorbate) 10,000-50,0000mg (10-50 grams), Coq10 300-500mg, Alpha Lipoic Acid 300mg, Selenium 200mcg, Vitamin e 800IU mixed Tocopherols. Don't listen to any death doctor when if they claim antioxidants may be bad with chemo, its hogwash. These will fight the tremendous amounts of free radicals generated by these treatments. For the other problems use Ginger, Peppermint etc.

Mushrooms are not an ideal food but the only ones which should be taken and especially for Cancer are SHITAKE and MAITAKE
