Methylene blue has been shown to shrink cancer tumours
By Rhoda Wilson on May 2, 2026
Methylene blue has been shown to shrink tumours and slow cancer growth by targeting cancer cell metabolism and energy production.
Photodynamic therapy with methylene blue uses light activation to destroy cancer cells while leaving healthy cells unharmed, making it a more precise treatment option.
Research on ovarian cancer found that methylene blue forces tumours to shift away from their preferred energy source, making them more vulnerable to treatment.
Unlike chemotherapy, methylene blue treatment does not cause significant side effects or toxicity, making it a promising option for patients with drug-resistant cancers.
Proper dosing is important. Just 5 milligrams of pharmaceutical-grade methylene blue per day is enough to reduce cellular stress and support mitochondrial health.

Introduction
Conventional cancer treatments often come with debilitating side effects. For example, chemotherapy and radiation therapy not only target tumours but also damage healthy cells, leaving patients weakened and vulnerable to infections. In an effort to find safer treatment options for patients, researchers are now testing the efficacy of methylene blue – a commonly used dye that enhances cellular energy production – in treating cancer.
