Here is another story that might add support to that idea.
Study helps explain fundamental process of tumor growth: Unique metabolic process first identified eight decades ago is found to be key
Read through the article and towards the end you find this:
The findings are consistent with the idea that tumor cells preferentially use glucose for purposes other than making adenosine triphosphate (ATP), the energy currency used by normal cells. “We suspect that this mechanism evolved to ensure that fetal tissues only use glucose for growth when they are activated by appropriate growth factor receptor protein-tyrosine kinases,” adds Cantley. “By re-expressing PKM2, cancer cells acquire the ability to use glucose for anabolic processes.
This is the same idea as in the ketogenic diet treatments - starve the cancer of glucose through a very low carb diet and you can stop it or slow it. Gary Taubes talks about this in Good Calories Bad Calories.
