@hch559 hi Helen, I'm sorry you're having recurring nodules. I can certainly empathize. have you heard of the Aliya pulsed electric field treatment? it's fairly new and can be a good option for nodules that can't be surgically removed. worth asking your dr about it. a few folks here have had it done with good results.

have you had a liquid biopsy by any chance? I'm wondering if you might have a genetic risk factor for lung cancer like I do. I have the T790M EGFR mutation. this led to me have 3 different lung cancers (each with its own activating mutation) at the same time. there's a team at Dana Farber in Boston that specializes in genetic lung cancer. They have an ongoing study called the INHERIT study that I imagine you would be eligible to join.
