Lung Cancer Cases Emphasize Early Detection and Environmental Risks

A 67‑year‑old woman, Lin, who had no smoking or drinking habits, suffered a life‑threatening type A aortic dissection and survived emergency heart surgery. During follow‑up, doctors discovered a 1.2‑cm ground‑glass nodule in her left upper lung. Using a 3D/4K high‑definition imaging system and video‑assisted thoracoscopic surgery, surgeon Dr. Zhuang Kaihao performed a minimally invasive resection, confirming early‑stage lung adenocarcinoma. Lin recovered quickly and was discharged after five days.

In a separate case, a 40‑year‑old secondary school teacher, Grace, also a non‑smoker, reported persistent back pain that was later diagnosed as stage‑four lung cancer with bone metastasis. Experts highlighted her frequent cooking without an exhaust fan as a major risk factor, alongside exposure to chalk dust and occasional second‑hand smoke. Professor Mo Shujin noted the prevalence of EGFR gene mutations in Asian non‑smokers and the role of high PM2.5 levels. He urged regular low‑dose CT screening for high‑risk individuals.
