Lung Cancer Risks and Early Detection: What You Need to Know
Lung cancer is a leading cause of cancer mortality, often developing silently before symptoms appear. Experts emphasize that early detection through low-dose CT scans and lifestyle awareness significantly improves treatment outcomes.
Lung cancer remains one of the deadliest malignancies worldwide, largely due to its tendency to develop silently in its early stages. According to data from the Israel Cancer Association, approximately 3,000 men and women are diagnosed with the disease annually in Israel, with about 2,000 fatalities recorded each year. While smoking accounts for roughly 80% of all cases, non-smokers can also develop the disease.
Dr. Emilia Hardak, a pulmonologist at Maccabi Healthcare Services in the northern district, emphasizes the critical importance of early detection and risk awareness. Although smoking intensity and duration directly elevate risk, passive smoking, workplace carcinogens such as asbestos, radon exposure, air pollution, and chronic lung conditions also contribute to the development of the illness.
Warning Signs and Symptoms
In early stages, lung cancer often presents no noticeable symptoms. However, individuals should remain vigilant regarding persistent coughs, unexplained shortness of breath, chest pain, coughing up blood, chronic hoarseness, unusual fatigue, and unexplained weight or appetite loss. Dr. Hardak notes that while these symptoms can stem from other common conditions, persistent or worsening signs warrant prompt medical evaluation rather than passive waiting.
Low-Dose CT Screening
For high-risk populations, low-dose computed tomography (LDCT) of the chest serves as a vital screening tool capable of identifying small tumors before symptoms manifest. In Israel, this screening is included in the national health basket for Maccabi members aged 60 to 74 who meet specific smoking criteria, defined as a minimum of 20 pack-years among current smokers or those who quit within the past 15 years.
Experts stress that screening differs from diagnostic evaluations. Anyone experiencing active symptoms such as a prolonged cough or blood in sputum should seek immediate medical assessment regardless of age or screening eligibility. Quitting smoking remains the most effective preventive measure, significantly reducing long-term risk across all age groups.
