The groundbreaking work of US cancer researcher Lewis Cantley, PhD, linking the ketogenic diet to an anti-cancer drug, is receiving prominent coverage in the medical media.
Dr. Cantley, who is based at Weill Cornell Medicine in New York City, is leading a research program in which a powerful anti-cancer drug is paired with the ketogenic diet in effort to starve cancer cells of the glucose and insulin they need to grow and spread. His work, now in clinical trials with women with endometrial cancer, was detailed in a new feature in The Medical Express this week.

A number of years ago, Cantley discovered a special enzyme, called PI3 kinase, which some are calling “the master switch for cancer.” As the article notes:
It turned out that the gene that encodes PI3K is the most frequently mutated cancer-promoting gene in humans — and in the years since Dr. Cantley’s revolutionary discovery, it has been implicated in as many as 80 percent of cancers, including those of the breast, brain and bladder.
Cantley is touted to be in contention for the Nobel Prize in medicine for his discovery. But now Cantley and his team have created drugs that inhibit PI3K. However, their research also found that despite the new drug’s ability to inhibit PI3K, the continuing presence of high insulin drives further cancer growth. How to get the insulin levels down? The ketogenic diet!
His groundbreaking work, in which PI3K inhibitors plus the ketogenic diet shrank cancers in mice, received prominent coverage in pre-eminent journal Nature in July 2018. Now the work has moved into clinical trials in humans.
In December, Dr. Bret Scher wrote about this promising avenue of research in a column for Diet Doctor. Dr. Scher’s post was a summary of a larger piece written by famous oncologist and author Dr. Siddhartha Mukherjee in The New York Times Magazine, which also describes Dr. Cantley’s ground-breaking work. Mukherjee was a co-author with Cantley on the Nature publication and a leading clinical researcher involved in the clinical trials of keto plus the PI3K inhibitor.

Said Dr. Scher of the work, and Mukherjee’s involvement:
How wonderful that this mainstream trial is about to get underway, especially with a curious and open-minded researcher at the helm. Knowledge is power, and shining the bright light of mainstream attention and resources on the potential of keto diets as an adjuvant cancer therapy is very good news indeed.
In a second story in the medical news this past week, a team of researchers, including post-doctoral fellows who had been working in Cantley’s lab at Weill Cornell Medicine, has discovered that high-fructose corn-syrup increases intestinal tumor growth in mouse models of colon cancer. The cancer growth was independent of obesity in the mice.
The study was published in the leading journal Science this past week. While the team of authors conclude the results are too early to translate into human cancer growth “these mouse studies support the hypothesis that the combination of dietary glucose and fructose, even at a moderate dose, can enhance tumorigenesis [tumor growth].”

In short, while much more research needs to be done, these are exciting times for novel cancer research, helping us better understand the role of glucose and insulin in cancer growth and using the ketogenic diet as a potentially powerful addition to new cancer therapies.

This is a link that shows the PI3K in the pathway of the mitochondria and it's link to insulin hormone and eventually down to cell replication.
I was not a big meat eater nor funded by meat industry. I went keto and tumors all shrunk & now down to the 1 big one (was the size of a large baked potato, now the size of a plum). Even conventional oncologist can feel the difference and the labs & CT scans all back up what I know, Keto works!
High protein can be just as bad as high carb or high sugar.
I have read that both keto and vegetarian diets can both work. The combination of high fat and high carb is what makes people ill particularly refined foods like bleached grains, high fructose corn syrup, and triglycerides. Better life through chemistry could be thought of as a joke gone bad. I lost the same amount of weight as you doing the low carb approach although I believe that either approach would have worked for me.
Thanks!
if none then it is probably just calcium and can be tender to the touch whereas cancer does not hurt.
Thank you,
Sherry
Warning:
Don't do any scans of CT, MRI... etc. NEVER allow contrast or any substance to inject into your body. It's a cancer promoting action.
