My nephew, age 37, had non small cell lung cancer in 2015. (non smoker) He had surgery to remove top 2 right lung lobes, followed with chemotherapy. Now, he is having a hard time breathing, while laying flat on his back. He had an xray this week that showed his esophagus is in the wrong place . He is incarcerated in a state prison, and we fear he will not get proper health care. Is this something serious we should push for him to have further tests, if so, what kind?
