NSCLC accounts for 85-90% for all lung cancers affecting the outer and central parts of the lungs. It involves formation of malignant cancerous cells on tissues in the lungs. This form of cancer attacks main airways, bronchioles and bronchi, rather than the small cells as in small cell lung cancer. Usually common in past and current smokers, NSCLC is widespread all over the world, and affects all age and gender groups. Exposure to radiation therapy, certain chemicals and a family history of lung cancers also increase chances of NSCLC. It grows and spreads at a lesser pace than Small Cell Lung Cancer, rendering it easier to localize, identify and treat through chemotherapy if detected at an initial stage.
HOW IS NON-SMALL CELL LUNG CANCER DIAGNOSED?
The three forms of NSCLC are Squamous Cell Carcinoma, Large Cell Carcinoma and Adenocarcinoma.
