Suzanne,
What is your location? My understanding is that PDT is not approved by the FDA so I think it is harder to find here in the U.S. I assume you already saw this article in the Medical Updates section but, if not, here is the outside link:

PDT was never offered as an option by my mother’s doctors but I called the Cancer Treatment Center of America because we are in Chicago and they have a facility in Zion, IL , and they said they do not offer it there, they offer it in Tulsa.
Another member, Mark, sent his Mom’s records to the Univ. of Virginia to see if she was a candidate, see the following post:

And here Stacie talks about a possible PDT study at MD Anderson:
