I’ve written a boatload of articles about cancer on this website. Admittedly, my interest is mainly based on the incredible harm done to people by fake cancer treatments, but others, like Science Based Medicine and the estimable Orac are experts in cancer, so I’ve just limited myself to sniping from the sidelines, like debunking the nonsense about weed cures cancer. But then I saw someone post a link to some pseudoscience about starving cancer. I just had to take a look.
I have a rule about cancer science. Anyone who oversimplifies prevention, development or treatment of cancer shall be treated with disdain unless it meets the standard of “extraordinary claims demand extraordinary evidence.” If you’re going to tell me that blueberry-kale shakes™ prevent cancer, I want overwhelming evidence in the form of meta-reviews.
Why am I such an aggressive skeptic about cancer? Because, if someone says “starving cancer is better than chemotherapy,” well that means some gullible person will take that advice and forgo more aggressive, and frankly more evidence based, treatments. And that patient could die, relying upon junk medicine.
Furthermore, I need to keep reminding my readers – and various people who push this nonsense – that there are approximately 100 to over 200 different cancers– the variation in numbers is a result of different definitions. Each of those cancers have a different etiology, pathophysiology, and treatment strategy. Starving cancer may actually be a brilliant idea – some research is involved in cutting off the blood flow to cancers. But that’s at a very localized level, and changing your diet will have approximately zero effect
On the other hand, I guess you could starve a cancer by starving one’s self. But I don’t think there would be a good prognosis and outcome for the patient.
Let’s take a look at the pseudoscience of starving cancer.
