Peter Attia talks about the same, and some interesting other considerations:

For which you'll likely have to lie to or find an alternative oncologist who's willing to tolerate adjuvant therapies that aren't 'standard of care'.
There are organizations that are developing protocols that include metformin along with statins, anthelmintics and even some antibiotics that are showing promise across a variety of research and even some clinical trials to help fight cancer through a number of mechanisms.

The kid in front of me, at Chiro school, was the spitting image of health. I was actually jealous. He was getting weekly adjustments. He was getting something called a Rotary Adjustment.
He was biking with his wife, and father in-law on a sunny Saturday. He stopped peddling, and fell over. Died of a massive stroke, at 25.
