I am so sorry to hear this. We are praying for you, your mother, and family for restoration of her health. Just like willywonka and hackersmeker said there are alternative options. Here are just a few that WORK.
Juicing
The Gearson's Therapy
Peroxide Therapy
The Big Pharma companies have a large percentage of society snowed as if they are the only ones who knows how to take care of the body or heal the body. This is so far from the truth it is sad. For example we all know radiation causes cancer but yet it is used to "treat cancer" or as a cancer treatment. This is a oxymoron method to treat cancer. Please don't give up hope and look into some of the suggested options mentioned by us on here.
May God with you and yours,
