Sorry, Tracey.

The photodynamic thing looked really hopeful to me, as a dye is injected that lights up the cancer cells, and the laser is trained to hit THOSE cells, not the healthy ones. The dye is a newer development.

Kaiser Permanente uses PDT, as do many dermatologists. Whether a researcher at KP would give this a go, or know a vet who would, I don't know.

It was just a thought...it seemed non-invasive, no "surgery" as such, and effective and I thought there might be a hope.

Hugs to Sunny.
