Photodynamic therapy destroys harmful cells, including cancer cells, using specialized drugs called photosensitizers or photosensitizing agents. Light activates these drugs and creates a chemical reaction that destroys the harmful cells.
After applying the photosensitizer, your doctor shines a special light on the area undergoing treatment. Depending on the treatment, your doctor may use low-power red laser light or natural sunlight. Under the light, the photosensitizing agent reacts with oxygen, causing a chemical reaction that destroys unhealthy cells.
Cost of therapy is covered under many extended medical benefit plans but not under our provincial medical services plan.
