Lung Cancer – Causes, Symptoms, Pictures, Treatment

Cancer may occur in any part of your body even in the internal organs. Lung cancer is the cancerous growth or tumor on the lungs. The tumors are of two types namely malignant and benign. Benign tumors are not harmful and can easily be removed since it will not spread to other parts. But malignant tumors are potentially dangerous since they attack the neighboring cells and tissues.

Lung cancer is dangerous since it is one of the most difficult forms of cancer. Lungs are vital parts of our body needed for respiration and any tumor like growth inside can lead to problems in liver and brain. Lung cancer has every possibility to spread to brain, adrenal glands and liver causing death. Two types of lung cancer are small celled lung cancer and non-small cell lung cancer. Non small type of cancer develops in almost 85% of lung cancer people. Metastatic lung cancer is the one which starts in any part of the body and subsequently spread to lungs.
