ATLANTA (CNN) -- Thearing a diagnosis of advanced melanoma, former President Jimmy Carter said he thought he had a few weeks to live, but was "surprisingly at ease" and that he trusted in the treatment prescribed by his doctors at Emory University.

The 39th president had learned in May that he had a "small mass" on his liver and decided to have the elective surgery to remove it on August 3. At that time the Carter Center, his nonprofit organization, released a statement saying "the prognosis is excellent for a full recovery."

But by August 19, a Carter Center statement told a different story. Tests after the liver surgery revealed the cancer was melanoma. An MRI revealed there were four spots of melanoma on his brain. Doctors said the small spots were about 2 millimeters in size.

Melanoma that has spread

Stage IV melanoma is a kind of cancer that starts in the cells that produce the pigment that gives your skin its color, known as melanocytes. Stage IV means it spread via the bloodstream or through the lymphatic system to other areas of the body.

Skin cancer is the most common kind of cancer in the United States, according to the Centers for Disease Control and Prevention. And melanoma is the deadliest form of it. According to the National Cancer Institute, an estimated 76,100 Americans will be diagnosed with melanoma and 9,710 will die from the disease this year. The exact cause of his cancer isn't clear, though; Carter said doctors will continue to search for the source. Some 98% of melanomas do start with the skin, and lessening your exposure to ultraviolet light does lower your risk of skin cancer.

The 90-year-old had a significant book tour planned this year to promote his latest memoir, "A Full Life: Reflections at Ninety," but decided to rearrange his schedule to fit in the treatment. At no point did he consider going without treatment, he told CNN Chief Medical Correspondent Dr. Sanjay Gupta. The former president said he would trust the advice of his doctors.

Focused radiation treatment

Thursday afternoon, Carter was to undergo radiation treatment.

On Wednesday, the hospital fitted him with a mask that will hold his head perfectly still to make sure the radiation goes into the right places in his brain. "Focused radiation as compared to general radiation has shown some success," said Dr. Manmeet Ahluwalia. "That they are really small makes it more likely that these lesions can be controlled."

Ahluwalia is Cleveland Clinics director of the Brain Metastasis Research Program and the associate director for clinical trials, and he has tested this kind of treatment.

Doctors also will give Carter the drug Pembrolizumab -- known by its U.S. brand name Keytruda -- intravenously. The Food and Drug Administration approved the drug in September 2014 to treat melanoma that cannot be removed by surgery, or a cancer that has metastasized. He has four treatments scheduled at three-week intervals.

"Most of the time we would use radiation on this kind of cancer but more recently, in the last couple of years, we were finding out drugs can impact brain metastases," Ahluwalia said. A presentation of a study at the American Society of Clinical Oncology this May showed that the drug has had some successes with patients.
