5 mos ago had a 1.5 cm Mucinous adenocarcinoma removed - along with the lower left lobe. We had watched it enlarge ever so slightly from 7mm to twice that over 4.5 years. I was told it is the “non smoker’s tumor” but he still took the entire lobe. I regret to this day not getting a second opinion because mine was located on the very periphery and all margins were clear -
and a wedge resection would have been very easy.

I have since learned that this tumor is frequently one people die with not of, because most often it is so slow growing.

All that said to say trust your own instincts and get second opinions. Your situation is different than mine. This will be your third run at it and that may be the critical difference in terms of how to react to it.
