Cancer wasn't on Michael Lax's radar, let alone cholangiocarcinoma, a bile duct cancer that affects just two out of 100,000 people each year. Since he didn't have a family history of the rare disease, it was a shock when he was diagnosed with it. His health deteriorated rapidly, and he underwent surgery at a local hospital. Lax remembers the word his doctors there used to describe his post surgical chance for survival: infinitesimal. But after seeking a second opinion at UCSF, he realized he had more options.
