In past 3years I have had 3 CT scans and 1 pet/ct scan all negative. Do I need more scans to rule out lung cancer? Still have fatigue and muscle loss

You don't have it. Whether scans cut a risk of one's actually dying of lung cancer is a question I will leave to policy-makers. But your fatigue and muscle loss are not due to lung cancer.

Uncommon. Most Zollinger-Ellison / gastrinoma are from islet cell tumors of the foregut. Oat cell carcinoma can produce other paraneoplastic syndromes, famously the anti-nerve cell ones, before being visible on chest ray, but it announces itself fast enough. And what are you going to without a localized tumor? Take out both lungs? Look for some other cause for any suggestive symptoms. Good question Gill. Read more...

Is it possible that CT scan shows no pleural masses while I have lung cancer and massive effusion?

Unusual but yes. CT scans have limited resolution. They do NOT see everything. Usually large pleural effusions come from significant disease, but not always cancer. The only way to tell is to have the pleural effusion drained & sent for cytology & other testing (culture). The lab techs can spin down the fluid, isolate cells or bacteria that may be causing it. Talk to a pulmonologist or your primary doc. Good luck! Read more...
