Anon! Look up these two things straight away:
1) The Beck Protocol (a kit of small electronic tools you can use at home to treat the cancer… SOTA Instruments in Canada is the major supplier of the kits though there are many others too).
2) The Gerson Diet (all over the search engines and youtube… basically shows how to adjust eating/drinking regimen to fight the cancer and is primarily based on vegetable juices).
I've seen several people cured of cancers up to Stage 4 using the combination of the Beck Protocol and Gerson Diet.
Your relative will get well soon with this. God bless you and your family.
