President Jimmy Carter discusses his cancer diagnosis.

Former President Jimmy Carter held a live press conference on Thursday morning to discuss his health, revealing that doctors have discovered four spots of melanoma on his brain. He had previously been diagnosed with liver cancer.

In typical fashion, he remained upbeat and positive regarding the latest diagnosis. He plans to begin radiation treatment later today.

Due to the intensive treatment, he said he would have to "cut back fairly dramatically on my obligations at Emory, at the Carter Center." He was asked about a planned Habitat for Humanity trip to Nepal and said that he would not be able to make the trip, but hoped that his family would still make the journey.
