Lung Cancer Screening
Method: Chest X-ray and sputum cytology
Chest X-rays are performed on all patients. Sputum cytology is an examination of the cells contained in phlegm and is mainly performed on high-risk individuals.
High-risk individuals comprise those 50 years of age or older with a smoking index (number of cigarettes per day x number of years) of 400, individuals with a smoking index of 600 or higher (including past smokers), or those who have had blood-tinged sputum within the past 6 months.
How to collect Your Sputum
Place a phlegm sample in the container after waking up, and do this for 3 days.
