Photodynamic therapy or PDT is a treatment that uses special drugs, called photosensitizing agents, along with light (referred to as Blue Light) to kill cancer cells. The drugs only work after they have been activated or “turned on” by certain kinds of light.
Over a certain amount of time the drug is absorbed by the cancer cells. Then light is applied to the area to be treated. The light causes the drug to react with oxygen, which forms a chemical that kills the cells.
Individuals with a higher likelihood of developing one or more AKs are those with:
*AKs develop as the result of years of sun exposure and are cumulative over time.
*Even if you didn’t suntan much, years of simple tasks can add up to significant damage (i.e. walking the dog, playing a sport, going to the mailbox).
