As photodynamic therapy works

If you and your doctor decides that photodynamic therapy for treatment of mesothelioma is right for you, you will first be given intravenous photosensitizing drug for a period of one to three days. This period is needed to make sure drugs have enough time to travel through the bloodstream and is absorbed by cancer cells. The process works because the cancer cells absorb these drugs more quickly, and stay on them longer than normal cells.

Once the drugs were administered, the next step is to simply shine the light of certain wavelengths of target cancer cells. Thanks to the photosensitizing drug, these cells will strongly react to light, releasing oxygen species that will spread to nearby cancer cells. This oxygen kills cancer cells, both directly and by damaging the blood vessels that supply them with nutrients.

The main side effect of photodynamic therapy of mesothelioma is increased sensitivity to light, which can last for a month or more. During this period, you need to carefully protect the eyes and skin from exposure to sunlight or other bright lights. This may be a requirement disappointing, but it's only temporary.

Who is a candidate?

This is not an effective treatment for cancer that has spread throughout the body, because they can not be entered in multiple locations or vast. She also works most effectively to cancer cells, which are located near the surface of the skin, which may include some types of lung cancer and some cases of pleural mesothelioma.

This kind of treatment can have side effects such as nausea, shortness of breath, pain in the area of ​​treatment. The result is usually recommended for patients who would otherwise be strong enough to cope with such symptoms. If you are concerned about any potential side effects of mesothelioma treatment, be sure to ask your doctor about how to cope with them.
