Hi, friend was just diagnosed with saliva gland cancer , they want to give him radiation and chemo. He is 64 otherwise in good health, good weight. Do you think that oxygen therapy would help ? Also, heavy doses of beet juice ? My Mom passed away one year ago today of this cancer and it took her in 4 months. So time is of the essence but she was 83 and not in great health. I wanted her to get hydrogen therapy and oxygen but she was not in a good place. Would you recommend them ?
