Multiple studies have examined metformin for its potential tumor and cancer fighting ability. The National Center for Biotechnology Information (NCBI) published such a study in 2016. Researchers found substantial pre-clinical evidence suggesting anti-cancer properties of metformin based on in-vitro and in-vivo analysis. Their analysis suggested metformin could be used as a radiation sensitizer or immunotherapy drug, besides its direct anti-proliferative properties .

In mice with lung cancer, metformin was used and researchers saw a 72% reduction in tumor burden. Tumors are known to exhibit the Warburg effect, but metformin blunts this and consequently downregulates the growth of cancer stem cells.

Several observational studies showed a correlation between metformin use and lessened cancer incidence. The results demonstrated that metformin users have statistically significant reductions in liver, pancreatic, colorectal and breast cancers.
