This deals with cancer "metabolomics". There's a growing research community that believes cancer is partially a metabolic disease. Metabolomics exploits the Warburg effect, and the notion that all cancers have altered energy production.

The general consensus is that many factors are necessary to induce cancer, including metabolic, genetic, and cell signaling issues. They are all interrelated.

There's hundreds of labs already working on metabolomics. There are a half dozen chemo drugs that attack the cell division machinery, but also target metabolism. There's also many more drugs that are not developed for cancer, but may exploit cancer metabolism, such as the drug, Etomoxir, which is highlighted in this UCSF study for TNBC. The trouble is that Etomoxir has been shown in clinical trials to be highly toxic. Another drug which is theorized to affect with cancer metabolimcs is the diabetes drug, Metformin, which is in over 150+ diferent cancer clinical trials. Another one that comes to mind is the old malaria drug, Chloroquine (CQ) and Hydroxychloroquine (HCQ). There's so many more. Most of these fall under "drug-repurposing", the small but growing effort to take old drugs and turn them into cancer drugs.

I hope your next PET scan shows slowing or regression, Slowdeepbreaths. Please let us know what your scan shows. It would be nice if some of the old (and cheap) drugs turn out to be effective cancer treatments, as JohnSmith mentioned.

I seem to recall reading that a low-fat diet is particularly beneficial to TN patients. This research would explain why. (I'd guess that a ketogenic diet should be avoided by this group!) Of course, it's hard to starve cancer, because it can be fueled by glucose, glutamine or alpha-ketoglutarate. But perhaps as the above research indicates, different types of cancer cells have different fuel preferences that can be exploited.
