CAROL LIN, CNN ANCHOR: Arizona Senator John McCain, he will meet with doctors again today. He does have a dangerous form of skin cancer known as malignant melanoma. CNN medical correspondent Elizabeth Cohen joins us from Phoenix, where the Senator has been staying, with an update. Hi, Elizabeth.</s>ELIZABETH, COHEN, CNN MEDICAL CORRESPONDENT: Hi, Carol, good morning. Carol, Senator McCain is expected to have surgery tomorrow on two malignant melanomas. One's on his temple, and one's on his arm. Now malignant melanoma is the least common but the most severe form of cancer. And yesterday, he had 3 1/2 hours of tests at the Mayo Clinic in Scottsdale, Arizona. And he's due to go back there today with his wife Cindy to get the results of those tests. CNN spoke with Mrs. McCain yesterday, and she said: We had a great meeting with doctors today. We see a great prognosis. And Mrs. McCain says that everything is normal in their household. Last night they went to the movies, and they had Chinese food with their children. Now surgery is the usual course of treatment for malignant melanoma. And what happens after that depends entirely on the stage of the cancer. If it's spread beyond the skin, the doctors sometimes use chemotherapy or immunotherapy, which are drugs to boost the patient's immune system to get the patient to fight the cancer. Now, some of the tests that Senator McCain had yesterday are used for exactly that purpose, to figure out if it's gone beyond just the skin -- Carol.</s>LIN: All right, thank you very much, Elizabeth.
