A Brief note on Cellular Transformation in Lung Tissues.

WYNNE MCBRIDE*

Lung cancer, commonly known as lung carcinoma because it represents for about 98–99% of all lung cancers, is a malignant lung tumour characterised by cellular transformation in lung tissues. Lung carcinomas occur from epithelial cells that have been converted into malignant cells, or from tissues made up of epithelial cells. Other lung cancers, such as the rare sarcomas of the lung, are caused by the malignant transformation of mesenchyme cells' connective tissues. Lung cancer can also be caused by lymphomas and melanomas.
