Lung Cancer: Characteristics, Indicators, Progressions, and Additional Details
Lung cancer, the third most common cancer in the United States and the leading cause of cancer-related deaths, is a significant health concern. The most common type, accounting for 80% to 85% of cases, is Non-small Cell Lung Cancer (NSCLC). To detect this disease at an early, more treatable stage, guidelines for lung cancer screening have been established for high-risk individuals.
**Who Should Be Screened?**
Eligible individuals are those aged between 50 and 80 years, with a significant smoking history. This includes current smokers or former smokers who have accumulated a minimum of 20 pack-years of cigarette smoking (a pack-year is equivalent to smoking one pack of cigarettes per day for a year). Former smokers who have quit within the past 15 years may also be included depending on individual guidelines. Additionally, some guidelines consider radon exposure, occupational exposures, personal or family history of lung cancer, COPD, or pulmonary fibrosis, but the primary focus is on age and smoking history.
**Screening Method and Frequency**
The standard and only recommended imaging test for initial lung cancer screening in eligible high-risk individuals is a Low-dose Computed Tomography (LDCT) scan. Chest X-rays are not recommended for lung cancer screening. Annual screening with LDCT is recommended for those who meet the eligibility criteria.
**Shared Decision-Making**
Shared decision-making between patient and provider is emphasized to discuss the benefits (early detection, potential to decrease mortality) and risks (false positives, radiation exposure, incidental findings). Smoking cessation should be strongly encouraged for current smokers undergoing screening.
**Not Recommended For**
Individuals with symptoms of lung cancer or a prior history of lung cancer are not recommended for screening. Those aged under 50 years or with less than 20 pack-year smoking history are generally not recommended for screening.
Regular screening may benefit people with a high risk of developing lung cancer. The American Lung Association recommends screening for people who meet certain criteria. Preventing lung cancer includes quitting smoking, avoiding secondhand smoke, avoiding radon and other toxins, eating a balanced diet, and speaking with a healthcare professional about reducing the risk.
Effective diagnoses and treatments, including chemotherapy and surgery, are improving the outlook for lung cancer patients. Regular screening allows physicians to detect changes more easily between scans to prevent false positives. Treatment options for lung cancer include surgery, chemotherapy, radiation therapy, radiofrequency ablation, targeted therapy, immunotherapy, and palliative therapy.
Anyone with concerns about lung cancer should speak with a healthcare professional. Early detection through regular screening is recommended for high-risk individuals who are ages 50 to 80, have a 20-pack-year smoking history, and currently smoke or have quit within the past 15 years.
