UNDERSTANDING LUNG CANCER
LUNG CANCER CLASSIFICATIONS
Lung cancer begins in the lungs, where cancer cells invade the cells lining the bronchi and other vital parts of the respiratory system, such as the bronchioles or alveoli. Understanding the types of lung cancer is crucial:
- Non-Small Cell Lung Cancer (NSCLC): This is the most common form, accounting for approximately 80% of cases. Most NSCLCs progress at a slower pace, allowing for more time for intervention. Within this category, there are subtypes like large-cell carcinoma and large-cell neuroendocrine tumors, which tend to be more aggressive.
- Small Cell Lung Cancer (SCLC): While accounting for 15 to 20% of cases, SCLC is notably more aggressive. This type is often found in active or former smokers.
- Other Cancers: This category includes mesothelioma, often linked to asbestos exposure.
Usually, noticeable symptoms don’t surface until the disease has advanced, underscoring the importance of early detection.
