Hair Dye Answers

My mum’s just found out that the cancerous tumours in her bladder are still growing after 6 months of treatment & that further chemo & surgery are no longer viable options. Does anybody have any suggestions about possible effective holisitc treatments? Anything, no matter how strange, like 5 pints of avocado juice a day, it doesn’t matter as all suggestions are welcome as long as they are based on tried & tested methods. Thank you =0)
P.S. She has already done the following: switched to completely organic food, uses natural toothpaste & deodorant, uses natural henna hair dye as opposed to chemical dyes, has limited use of aerosols & household cleaning products, & has tried a bit of homoeopathy, although she didn’t continue due to some scepticism, despite my fervent belief in the benefits of it.

my dad would let me dye my hair if it was organic, because he is convinced it gives you cancer.
