Lung cancer is a form of very rapid growth of cells (abnormal) in lung tissue caused by changes in tissue form cells or expansion of the cells themselves. If left to this abnormal growth can be spread to other organs, both near and far with a Pulmonary example bone, liver, or brain.
Lung cancer caused by smoking more (87%), while the remainder is caused by the substance of asbestos, radiation, arsenic, chromate, nickel, klorometil ethers, mustard gas and coke oven emissions can cause lung cancer, although usually only occurs on workers who also smoked.
Classification for Lung Cancer
There is the classification of lung cancer, is viewed from both dijaringan lung diffusion rate itself and to other organs. But basically the lung cancer is divided into two levels of criteria based on their distribution:
1st. Primary lung cancer
Has 2 main types, namely Small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC). SCLC is the kind of small cells (many) which has a very rapid growth in power until engorged. Usually called "oat cell carcinomas" (wheat cell carcinoma). This type is closely associated with smokers, Handling responds well enough by the action of chemotherapy and radiation therapy.
While the growth of NSCLC cells is a single, but often strike more than one area in the lungs. For example adenoma, Hamartoma kondromatous and Sarcoma.
2nd. Secondary lung cancer
Lung cancer is a disease that arises as a result of the spread of cancer from other organs, most often breast cancer and colon cancer (stomach). Cancer spreads through the blood, lymphatic system or due to closeness of organs.
