Photodynamic therapy is a medical procedure that's primarily used to treat patients suffering from certain forms of cancer. Since the therapy involves the administration of photo-sensitizing drugs (medications that are activated after they're exposed to a light source), cancerous cells or tumors that are closer to the surface of the skin can be treated because the light may not be able to penetrate the inner areas of the body.
Cancers that are Cured
Photodynamic therapy is currently used to treat esophageal cancer and non-small cell lung cancers. This therapy is often used in conjunction with radiation therapy, chemotherapy or surgical procedures to get rid of cancerous cells and tumors. Apart from directly destroying cancerous cells, photodynamic therapy also encourages the immune system to get rid of cancerous cells.
Photodynamic therapy can also be used to treat patients suffering from wet macular degeneration.
Alternative Uses of Photodynamic Therapy
Although photodynamic therapy only treats certain cancers mentioned above, research is being carried out to determine the benefits of this therapy on patients suffering from brain cancer, skin cancer and cervix cancer. Researchers are also trying to find out if this therapy can effectively treat acne and psoriasis.
The success rate of the treatment depends on the type and severity of the skin condition you're suffering from. When used along with other treatment options, it may prove more effective.
