What is a Lung Cancer?
Lung cancer, additionally called lung carcinoma, is a malignant lung tumor characterized by uncontrolled cell growth in tissues of the lung.
This growth can spread beyond the lung by the process of metastasis into nearby tissue or alternative components of the body.
Most cancers that start in the lung, known as primary lung cancers, are carcinomas. The two main types are small-cell lung carcinoma (SCLC) and non-small-cell lung carcinoma (NSCLC).
Stop Cigarette smoke
Smoking causes 90%of carcinoma cases. It also has a link to over a dozen different types of cancer.
Cigarettes have about 250 harmful chemicals, and sixty-nine of them cause cancer. It doesn’t matter how much you smoke.
Even one smoke each day puts you in danger of lung cancer. The vast majority (85%) of cases of lung cancer are due to long-term tobacco smoking
