In 2011, Sunshine Pegues was diagnosed with stage 4 non-small cell lung cancer. Standard treatment at the time was chemotherapy followed by 35 days of radiation, which burned the skin on her neck and left her in more pain and skeptical about the advice of her health care team. She moved back to her hometown, Seattle, where she enrolled in two clinical trials. The second trial tested nivolumab (Opdivo), an anti-PD-1 immunotherapy, which stopped her cancer from progressing and eventually, caused it to become inactive.
