In my old age I stay as far away from the medical community as I can because they have nothing but poison to offer you and most honest doctors will tell you it's the best option they have because they don't know better.
There are natural options out there right now ... if it comes fast enough we will get to the new earth where there will be no more dis -ease but in the meantime we are tasked with finding the best options we can outside the medical mafia.
Here is a possibility
But, there are many more you just need to go within and ask to be guided to what your beautiful wife needs. My prayers include her as well as the many hurting souls out there that feel helpless in the face of losing loved ones.
With love and light for all.....
