Lab studies explore how methylene blue interacts with light and cancer cell energy use. Human evidence is thin, and the drug-interaction risks are serious.

A meta-analysis of small randomized trials linked melatonin to better tumor response and one-year survival, but later blinded trials did not confirm the benefit.

Methylene blue is approved for one blood condition and studied in cancer cells and mice. No human trial shows it treats cancer, and it interacts with common medicines.
