Hi! I am posting from India. My uncle had been detected with cancer in the jaw around three years ago. Right now,there is a reocurrence in the right cheek. Doctors say its in the initial stages and have suggested Photo Dynamic Therapy (PDT). He will start with the therapy on wednesday.

I would be grateful if anyone could share any information / their own experience of undergoing the therapy. Specifically the side effects, the success rates, anything he should be careful about. I could not get any links which go beyond very preliminary information, so please do direct me to right place if you can.
