"Cancers of the head and neck tend to be more aggressive than other types of cancers," says Dr. Anurag Singh. Singh is a radiation oncologist at Roswell Park who specializes in cancers of the head and neck.

He's not involved in Jim Kelly's care for his recurrence of cancer, but has treated hundreds of patients for head and neck cancers.

Dr. Singh says it's likely Kelly will go through six or seven weeks of radiation and chemotherapy for what Jill Kelly has said is an aggressive form of cancer that's in Jim's maxillary sinus.

Dr. Singh: "When approaching with radiation the difficulties are there are a lot of valuable organs in that area, including the eye and the brain, and so you have to be very careful with your approach to limit the doses to those normal structures while giving the tumor all the dose that it needs to be treated."

On Wednesday in a statement, Kelly's doctor at Lenox Hill hospital in New York, Dr. Peter Costantino, said Kelly's cancer was "very treatable and potentially curable."

Scott Brown: "Is there a way to live with this type of cancer and manage it?"

Dr. Singh: "No this is a cancer that you either cure or you die from. So if the doctor is saying this is potentially curable then it should mean that it's localized and that with proper therapy they're hoping to achieve a cure."
