My husband was also diagnosed with Non-Small Cell Lung Cancer in 2021, Stage 3 Adenocarcinoma. His was unresectable so he was given Chemo and Radiation. He later developed Plural Effusion and Pneumonitis. For the Plural Effusion his doctor drained off 1.5 liters one time only, and since then he only has a small amount of fluid - not enough to require draining again. His scans have all been clear and he is almost at the two year remission mark. There was talk about giving him Immunotherapy, but for some reason his doctor is no longer going that route. We don’t know if it is because of his age (67) or some other reason. Are you scheduled for Immunotherapy?
