Krishnan,
Dattoli is a radiation oncologist, and I think he is/was Dr. Myer's doctor. Dr. Myers refers many patients to him for scans and radiation treatments. However, I think you would be better served with a medical oncologist first. Like davidg mentioned, I am sure some of our Florida guys will chime in and mention a few reputable medical oncologists from that area.
Dr. Myers is one of my doctors and he is accepting new patients, but he is in Charlottesville, Virgina. He doesn't take insurance for his appointment(s) and he is rather expensive. But, I do believe he understands this disease like few others.
Welcome to our little part of the world called Hearling Well. Regardless what you decide, do not hesitate to keep in contact with us. Unlike Myers, we are not expensive...we're free...and you've found a great place to bounce ideas, gain information, and get support...
