I have heard of PDT and know of a test currently ongoing at Northwestern in Chicago. I believe the early results are very promising. From what I understand in oral cancer the medication can also be applied topically and then the area is exposed to a laser which only attacks the cells that have absorbed the drug. Healthy epithelial cells then replace the cancerous ones.

I was unable to participate in the Northwestern study because you had to be cancer free for two years. I hope that you will be able to participate in the Penn study and I wish you the best of luck!!
