I am writing for my dear sweet husband who diagnosed 13 months ago with small cell lung cancer that metastasized to his lymph system, liver, and his brain. After chemo, and radiation to his brain and chest, he started Opdivo. Opdivo did a great job reducing his tumors, but then attacked his lungs. He is currently off treatment and on a huge dose of steroids. He is being treated at Cancer Treatment Centers of America.
