A 101-year-old woman, a non-smoker, recently had chest tightness and shortness of breath during meals without coughing, coughing up sputum and hemoptysis, and a right lung mass/pulmonary effusion with elevated tumor markers on CT. Elderly patients with lung cancer can hardly tolerate traditional surgery and radiotherapy because of the declining function of their organs and insidious symptoms.
