I personally know a guy who runs a cancer support group at a nearby church who had 5 cancers around the same time including liver. He was given less than a year. I learned about him from my FM doctor. The guy used Budwig protocol, low stress, strict low carb but not a very extensive protocol. He is alive 5 yrs later and doing well.

Someone mentioned Hoxey. This is one of the most amazing recover stories I've come across. I first saw the guy in the Global Quest series of The Truth About Cancer--TTAC. This is the clinic in Tijuana that continues Hoxey protocol

I think Chris Wark had colon cancer--maybe 3C. The surgeon may have "gotten it all" So his case is not the most impressive. He turned down chemo but supposedly he had half decent odds of success after the surgery. However he has interviewed more impressive cancer survivors. You might also check out his coaching to try to pick up leads.

If you can get your hands on a copy of Dr Major's book Cancer Killers he lays out the comprehensive protocol he used.

Dr M. had multiple melanoma that had spread to his brain. It was inoperable and he was given just weeks to live if he did not accept mainstream treatment, maybe a year if he did. He went to Nevada where there is more medical freedom for integrative doctors. They have their own medical board so are not persecuted so much by the mainstream board.

Majors wrote the book roughly 2 yrs later. After 5 yrs he was "cancer free" and he seems quite healthy from his videos during those years; however in year 6 the cancer returned aggressively and killed him rather quickly. In his book he said he planned to stay on the protocol for 5 yrs. Maybe he stopped it too soon : (. https://www.youtube.com/results?search_query=Dr+Charles+majors&page=&utm_source=opensearch

In Majors' protocol I see the strong influence of Dr Gonzalez and his proteolitic enzymes--(chymo)trypsin, low protein diet, etc. He also used curcumin, immune system support, Vit D, etc.

The theory about dental infections contributing to cancer is quite interesting. Dr J Tennant is excellent on the subject. I liked his book about cancer although it is pricey.

Dr Kleinwaks had his very late stage abdominal tumor disappear less than 2 months after dental cleanup. Dr Grube in Scranton did the dental work. She says her leukemia-related blood tests normalized in less than two months after her dental cleanup by Dr Huggins.

Both Dr K and Dr G speak about it here.

I really think Dr Gonzalez and his enzyme therapy is a valuable intervention. It has a long track record going back 100 yrs to Dr J Beard at a U. in Scotland. There are good youtube interviews as well as some good radio interview recordings on his foundations's site.

I consider Dr Tennant as an extension of the Beard-Kelly-Gonzalez tradition. Those who are interested in Rife and similar technologies must check out Tennant.

For those who can't afford to purchase the high doses of enzymes, a Dr. Dyliacco in the Philippines and a couple of his patients described impressive cures from using raw pancreas they got from the butcher. These were poor or modest income folks. Dr Dyliacco himself was cured of prostate cancer decades ago. He learned about Dr Kelly and enzymes when he worked as an international VP for a US company. He might have been the most impressive interview in the entire TTAC Asia series of videos.

Of course, curcumin is a staple in natural cancer treatments.

If you have a pile of $ check out Burzynski but he is better known for brain cancer.

Dr Majors also used Dr Hilu in Spain.
