Lung Cancer is a type of cancer that begins in the lungs, which are part of the respiratory system.
It occurs when cells in the lungs grow uncontrollably, forming a tumor. There are two main types of lung cancer:
- Non-Small Cell Lung Cancer (NSCLC)
This is the most common type, accounting for about 85% of cases. It includes subtypes like adenocarcinoma, squamous cell carcinoma, and large cell carcinoma.
- Small Cell Lung Cancer (SCLC)
This type is less common but more aggressive and tends to spread quickly.
