Yes whilst healing the body remove all animal protein until totally healed as the Cancer thrives upon it. Now get yourself quality tinctures of blood cleaning and Liver boosting herbs. You would want Berberis, Greater Celandine for the Liver whilst say Red Clover, Chaparral & Burdock Root for the Blood. You can use high liver boosters as the Cancer is not within the Liver. He should be eating one medium pineapple a day and if possible x-amount of Papayas daily ASAP! If his Kidney's are working normal then he should be taking in Cayenne Pepper in hot tincture form and utilising Cayenne very much so. Take 5ml of a tincture 5 times daily. He should be on UNpasteurised Kombucha tea ideally 500ml-1000ml a day but gradually working up to this level from 200ml and so forth. The Cayenne will sharp get to his lungs. Ozonated distilled water 6ml nebulised into the lungs will do wonders but I suggest this after a while of some of the other work to reduce any Herxheimers as your going direct you see. Theres more things you can do. Also while I quickly think utilise the POTASSIUM BROTH of Richard Schulze
's. Also get him daily in an infrared sauna for three hours continous with plenty fluids. He won't feel the heat so much like you do in normal saunas. You can pick these up cheap enough these days with these material fold around systems. Hopefully you will hit some of the tumour with up to 104-6 degrees of heat and whack it as normal cells dissipate the heat whilst Cancer cannot.
