Former President Jimmy Carter announced to the world last summer that he had been diagnosed with melanoma that had spread to his liver and brain. Just months later, after receiving a groundbreaking, personalized treatment known as immunotherapy, his cancer was in remission.

I was fortunate enough to attend President Carter’s Sunday school class this May in his hometown of Plains, Georgia, and can tell you he is doing fantastic! As an oncologist in Nashville, this kind of story is why I decided to make treating cancer patients my life’s work.
