Brittany's book

Has anyone read Brittany's book "Keeping Well"? The amazon link is here: https://www.amazon.com/Keeping-Well-Anti-Cancer-Remain-Remission/dp/1642799637. I'm sure she has good information on the lifestyle impacts of cancer diagnosis, but as a medical scientist a lot of the info on the page rubs me the wrong way. She claims to be a "detoxification specialist" from "the international school of detoxification", which does not seem to be accredited or even legit. She also also seems to have no scientific background in cancer biology.
