Thank you Dr Zhao for sharing your knowledge about Lung cancer especially for female who does not smoke. In Aug 2021, I did a Calcium Score Test (for my heart health) & found out I had a shadow the size of a 20c piece on my right lower lobe. Biopsy was carried out & confirmed it was cancer. I had surgery to remove a portion of my lower lobe & went thru 16 weeks of chemo. I see my oncologist every 6 months & he will monitor me for 5 years. Every six months I would either do a CT Scan or Xray. 🙏🏻. I am from Aust.
