  Description
Lung cancer is a disease characterized by uncontrolled growth of abnormal cells in one or both lungs. If the cancer starts in the lung, then it is called primary lung cancer. It is called secondary when the cancer comes to the lungs from another part of the body by metastasis.

The primary symptom is a permanent cough that gets worse over time. However, in some cases lung cancer does not have initial symptoms.

There are two types of lung cancer:

- Small-cell lung carcinoma (or SCLC). It is the fastest growing type, and
- Non-small-cell lung carcinoma (or NSCLC), which is the most common type.

Risk factors

It is believed that the most common causes of lung cancer are the long time exposure to certain substances including:

- Smoke from tobacco (including passive exposure)
- Radon gas
- Asbestos
- Polluted air In addition, genetic factors can play an important role in the development of lung cancer.
  Diagnosis
Doctors may order the following tests and procedures to confirm the diagnosis:

- Chest X-ray

- Computed tomography scan (CT)

- Biopsy (from the lung)

- Bronchoscopy
