Brandon, I agree strongly with your Chemo Doc.
You have an Aggressive recurrent cancer. If you want to survive this , you must treat it aggressively. Treat it with the treatments that have been proven to work. Surgery coupled with chemo and or radiation . Why would you not listen to the Drs who have huge experience with treating this type of cancer?
Your white cells will recover from the chemo. Hopefully the cancer cells won't.
Will a ketogenic diet help? Absolutely not.
I don't want to read of your demise because you got sucked in by woowoo.
Please ,please, listen to the experts in this.
