Photodynamic Therapy for Mesothelioma Patients

This new approach, based on killing cancer cells with light, is still experimental for mesothelioma treatment, but it has shown promising results with other cancer cells. Your doctor would inject a drug that collects in cancer cells but not in healthy cells. Called a photosensitizer, this drug makes cells sensitive to certain wavelengths of light. Next (usually by opening the chest cavity) your doctor would place fiber optic cables inside you to focus the right frequency of light on the tumor. Then the drug that's been injected into the cancer cells produces toxic oxygen molecules that kill the cells.
