Where cancer spreads may depend as much on an organ’s metabolic menu as on the tumor’s genes.

The study linked in the post makes exactly that case: it describes cancer cells spreading to organs where their energy needs line up with the local environment, a concept called metabolic matching. Other research supports this from several angles. Pancreatic cancer cells appear to use cholesterol metabolism to adapt to different organs, and melanoma cells can exploit the liver’s high insulin and glucose environment — blocking that loop reduced liver spread but not lung spread. Liver metastases have also been linked to special fat-related conditions and certain bacteria, though that work is a mechanistic proxy and doesn’t prove the whole idea. For the broader claim that metastasis isn’t just about genes, the linked review points to nutrients, oxygen balance, and organ surroundings, while other research highlights tumor-derived particles and bone tissue reprogramming cancer cells. Together, the evidence is consistent with the post’s argument, though it focuses on particular cancers like pancreatic, melanoma, and lung cancer.
