Understanding Lung Cancer: Causes and Risks
Lung cancer occurs when cells in one or both lungs grow abnormally. In healthy lungs, cells replicate at a normal pace, creating functional lung tissue. However, in damaged lungs, this rate of cell division becomes abnormally fast, forming cancerous cells that clump together to create tumors. These tumors disrupt normal lung function, leading to noticeable symptoms of lung cancer.
The Causes of Lung Cancer
Lung cancer often develops over several years. However, cellular changes can begin quickly after exposure to harmful substances such as cigarette smoke, radon, asbestos, coal, air pollution, and even secondhand smoke. These contaminants damage the lungs, triggering abnormal cell growth.
Who is at Risk?
Lung cancer can affect anyone, regardless of gender, age, or race. Although it is more common among smokers, non-smokers can also develop lung cancer. This condition is rare in non-smokers, accounting for about 10% of cases, while smoking is linked to nearly 90% of cases. This is largely due to the lungs' primary role in filtering the air we breathe. In smokers, carcinogens from cigarette smoke impair this filtering mechanism, allowing harmful substances to penetrate deeper into the lungs, leading to cellular damage.
The Impact and Diagnosis
Lung cancer is the leading cause of cancer-related deaths in the United States and has no known cure. Unfortunately, by the time it is diagnosed, the prognosis is often poor, with many patients not surviving the first year after diagnosis. There are two main types of lung cancer: small cell lung cancer and non-small cell lung cancer, with the latter being more common, comprising 80% of cases. Non-small cell lung cancer spreads more slowly but can metastasize to other body parts, complicating treatment.
Sophisticated lung scans are the primary method for detecting tumors, but they are not typically included in routine medical exams. This lack of regular screening contributes to late diagnoses, making early detection and treatment challenging.
Lung cancer remains a critical health concern that emphasizes the importance of preventive measures, early detection, and ongoing research for effective treatments.
