Hi Terence,
It is a difficult decision to make, but really there isn't anyone in the world that can make it but your wife and you.
However, I'll give you my 2 cents worth of opinion.
Should you decide to take some more chemo rounds, you might wish to ask your doctor to prescribe Persantine (dypiridamole) 300 mg per day This helps prevent MDR.
"Multiple drug resistance (MDR) is the bane of all practitioners --conventional or otherwise. MDR closes the door to future chemos and to most natural treatments also" (Gammill, 2003).
From the little you wrote I gather that you are using a corrective protocol or approach. This is good and important, however, it does take a great deal of finesse.
I'm not quite sure what it is exactly you are using, and whether her cancer is ER-positive or ER-negative. Agreat deal of information is missing. It is almost impossible to give individual advice on the internet, so I will not. However, I hear especially good things about the following natural substances with regards to breast cancer, which you and your wife might want to further investigate:
High dose Melatonin
I3C (preferably DIM which is what the body converts I3C into), synergetic with D' Glucarate.
ARTEMISININ
Budwig FXO/CC
High dose curcumin
Haelan - afermented soy drink. It is expensive ($50 a bottle)
I would consider it if money is not a consideration.
Se-Methylselenocysteine - it is a very good form of organic selenium.
CoQ10
Vitamin E - mixed Tocotrienols and Tocopherols (not the synthetic one)
Last,but not least are the all important anti-cancer diet, cleanses, light physical activity, body/mind techniques and most of all a positive attitude.
I hope this is of some help, and wish your wife a complete recovery.
Sincerely,
Gubi
