My husband recently underwent a lung biopsy on a tumor that was found and it showed necrotic cell and non-diagnostic. A CT was then done and showed mediastinal LNs. A Upper Endoscopic Ultrasound was then performed and it showed multiple large hypoechoic subcarinal LNs. No celiac LNs were seen. The initial test showed no cancer cells at the office but was sent to a pathologist for results just to confirm. What does all this mean ? The doctor after the lung biopsy just told me that the tumor sample tested came back as dead cells. I don't quite understand does it mean he doesnt have lung cancer or what. His elevated alpha-feto protein level and lung lesion is why they suspected the cancer in the first place.
