Photodynamic Therapy (PDT) is a (relatively) new modality in cancer therapy.
It is based on the selectivity of cancer cells to retain a number of photosensitizers (in comparison to normal cells).
Following activation of the drugs (photosensitizer) by a light of a specific wavelength delivered through fiber optic, a selective necrosis will take effect only on cancerous tissue.
The tumour is selectively destructed by fiber optic delivery of relatively low light energy.
There is interval time of the photosensitizer injected intravenously and light illumination due to the longer capacity of cancer cells to retain the drug.
The normal cells will escape the photochemical destruction of PDT.
The author will describe application of PDT in nasopharyngeal cancer which nowadays could be considered as an effective local treatment for recurrent or persistent nasopharyngeal carcinoma.

Its like you read my thoughts! You appear to know a lot approximately this, like you wrote the e-book in it or
something. I believe that you simply could do with a few %
to drive the message house a little bit, but instead of
that, this is magnificent blog. A fantastic read.
I will certainly be back.
