Non – Small Cell Lung Carcinoma

NSCLC refers to a group of closely related lung cancers which behave similarly in terms of growth and treatment. NSCLC makes about 85% of all the lung cancer cases. Unlike small cell lung cancer, NSCLC tends to grow and spread more slowly, and it may be detected at an earlier and more treatable stage.

Types of NSCLC:

  1. Adenocarcinoma: It is the most common, especially in non – smokers and women. It begins in the glandular cells that line the lungs, often in the outer regions.
  2. Squamous Cell Carcinoma: It is typically found in the central part of the lungs. It arises from the flat cells that line the inside of airways and is strongly linked to smoking.
  3. Large Cell Carcinoma: It is an aggressive and fast – growing form that doesn’t fit into the other categories and can appear anywhere in the lungs.

Yes, especially in cases with high PD – L1 expression. It helps the body’s immune system to recognize and attack cancer cells.

Typically after every 3-6 months for the first 2 years, then annually. Follow – up indicates CT scans, blood work, and clinical evaluation.
