One of the most common yet dangerous types of cancer that people suffer worldwide is lung cancer. It occurs from the abnormal growth of cells present within the lungs. This leads to the development of a malignant tumor in the lung. Usually, lung cancers are fatal and have an extremely low survival rate. The main reason is that cancer spreads to other organs or parts of the body very quickly and often before diagnosis.
Types of Lung Cancer
There are two types of lung cancers depending on the appearance of the cancer cells beneath the microscope. These include –
Non-small cell lung cancer or NSCLC: Non-small cell lung cancers are observed in different variants and are actually an umbrella phrase. These include large cell carcinoma, adenocarcinoma, and squamous cell carcinoma.
Small cell lung cancer or SCLC: This type of lung cancer is less common when compared to non-small cell lung cancer. This usually occurs in heavy smokers.

Causes of Lung Cancer
The majority of lung cancer cases are associated with smoking. That is because smoking is indeed a risk factor that can lead to the development of lung cancer. When you inhale the cigarette, the smoke enters the lungs and starts to damage the underlying tissues. It is important to understand that the lungs have the capability to repair the damage.
However, when this continues for a prolonged period of time, the lungs find it difficult to make the repairs again and again. If the cells are damaged, abnormal activities begin. This eventually leads to an increase in the chances of lung cancer. That is why it is recommended to stop smoking. Your chances of having lung cancer reduce significantly.
Passive smoking, which is the inhalation of the smoke that non-smokers face, can also lead to lung cancer. It is a proven risk factor associated with this disease.
Another factor that can cause lung cancer is exposure to radioactive gas, radon. Apart from that, breathing hazardous substances over a prolonged period of time can cause lung cancer too. Mesothelioma, a type of lung cancer, occurs due to asbestos exposure.
There are some other substances that can contribute to the development of lung cancer. These include exposure to uranium, arsenic, nickel, chromium, cadmium, and a few petroleum products.
