Cancer is now the number one killer of Americans under 85. More than thirty years after the government declared war on the disease, it refuses to surrender, claiming nearly 1,500 lives every day in America. In this hour, Dr. Sanjay Gupta goes inside this brutal war, to the front lines of M.D. Anderson Cancer Center in Houston, Texas, where every day thousands of patients, doctors, and practitioners fight against this terrifying enemy. Gupta takes us to meet those both finding cures--and living them. For many patients, the cancer center is a last stop, when cancers either rare or advanced force them to search out cutting edge cures. CNN Presents goes deep inside this world-renowned medical complex to see the battle up close--the most promising new ideas, the disappointments, and the risky and life-saving science. And, we see it all through the eyes of those living with the disease.
