Gene therapy: What personalized medicine means for you

Thuy Truong thought her aching back was just a pulled muscle from working out. But then came a high fever that wouldn't go away during a visit to Vietnam. When a friend insisted Truong, 30, go to an emergency room, doctors told her the last thing she expected to hear: She had lung cancer. Back in Los Angeles, Truong learned the cancer was at stage 4 and she had about eight months to live. "My whole world was flipped upside down," says Truong, who had been splitting her time between the San Francisco Bay Area and Asia for a new project after selling her startup.
