Mesothelioma — a type of cancer caused by exposure to asbestos — is fairly new and difficult to diagnose and treat. Current treatments are surgical removal of affected tissue, chemotherapy and radiation, depending on the stage of the disease.

But a new type of treatment has been introduced to the mix. Photodynamic therapy uses light to kill cancerous cells after a drug is administered intravenously to target and render the cells more sensitive, says a press release put out by PRWeb.

The drug has no affect on normal cells, so no additional harm will be done. After cells have been properly exposed, a special frequency of light laser beams are directed toward the mesothelioma. Although there have been cases of eye irritability and nausea, side effects have been minimal.
