Given that cancer cells are fueled by glucose (i.e., sugar metabolism), you might read up a bit on carb-restricted diets:

"Since cancers can't really get nourishment from anything but glucose, it stands to reason that cutting off this supply would, at the very least, slow down tumor growth, especially in aggressive, fast-growing cancers requiring a lot of glucose to fuel their rapid growth. Thomas Seyfried [showed] that ketogenic diets in animals and humans can stop malignant brain tumors."

Please, please do not suggest treatments for your friend, especially those suggested by people on the internet.

People on the internet may mean well and show you interesting things, but your friend's medical care is best managed by his oncologist/primary care physician. Interfering with their work will likely do more harm than good.

Definitely encourage your friend to ask any and all questions about his care; communication between doctors and patients is helpful for everyone involved.

Self-medication, whether by diet or drugs, is a terrible idea. People die doing this.

agree with spartango. Cancer is extremely complex and any simplistic approach is BS (or a money grab). Staying away from the internet and asking questions directly to the oncologist is usually the best thing to do.

This doesn't pass a smell test as far as I can tell. Tumors adapt. http://www.cell.com/retrieve/pii/S0092867412015504?cc=y

Fructose. Otherwise agree on low carb, especially no HFCS.

A buddy got prostate cancer, switched to only meat and veggies, survived (then 10 years). I have no idea it it helped. At the time I thought he was cuckoo (for Cocoa Puffs). But now that I've adopted the troglodiet (tm), I think maybe he was on to something.
