hi dont know if this is any help for you
my wife also had kidney cancer which went to both lungs with no option of chemo or operation.
i gave her ncd zeolite and it took 3 weeks for her energy to return and four months for the cancer to stop spreading and growing
after 4 mths doctors changed there minds as it had stopped and took out the last 2 tumours she was originally given approx 6 mths to live
she has now had 3 scans and is cancer clear.
i am not selling you ncd but it worked for us
