Hi, and welcome. I don't know much about cavitary vs non-cavitary lesions, so can't speak on that. but I was diagnosed with a 1.1 cm Adenocarcinoma of my RLL at end of August, 2022. I had a small area of invasiveness in the same lobe, and negative nodes. That's a stage 1, as I expect yours might be too. Did you have a lobectomy or wedge resection?
So far, I am NED (No Evidence of Disease) at 9 months post-diagnosis. I did not require chemo or radiation, and since I have a history of smoking, I wasn't tested for targetted therapy. The 6 month CT scan (neck to knees) was negative. The surgery itself was difficult for me. The initial 6 weeks after the lobectomy were difficult, with many after-effects from the surgery including nausea, pain, low energy, bloating, a cough and shortness of breath. Most everything bad was gone by 6 wks. I still have some shortness of breath when i exercise or on "bad air quality" days. I had a month of physical therapy to regain strength and stamina which helped enormously.
It's normal to be in shock and scared, but lung cancer isn't necessarily the beast it used to be.
