What are the two major types of lung cancer?

The two major types of lung cancer are classified as non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC). This classification is based on the behavior and growth patterns of the cancer cells.

Non-small cell lung cancer encompasses a variety of subtypes, including adenocarcinoma, squamous cell carcinoma, and large cell carcinoma. It is the more common form of lung cancer, accounting for approximately 85% of all cases. NSCLC tends to grow and spread more slowly than small cell lung cancer, making it more amenable to surgical interventions in the early stages.

On the other hand, small cell lung cancer is known for its rapid growth and aggressive behavior. It typically begins in the larger airways and is often associated with smoking. SCLC is more likely to spread to other parts of the body early on, which can complicate treatment options.

Understanding these classifications is crucial for determining appropriate treatment strategies and predicting patient outcomes. The distinction between NSCLC and SCLC is a cornerstone in the management of lung cancer, guiding both diagnostic approaches and therapeutic protocols.
