Fatigue

Causes of Lung Cancer

The primary cause of lung cancer is long-term exposure to tobacco smoke. Other risk factors include exposure to secondhand smoke, air pollution, and occupational hazards such as asbestos and radon. In some cases, genetic factors may also play a role in lung cancer development.

Diagnosis of Lung Cancer

Diagnosing lung cancer typically involves a combination of tests, including:*
Physical examination and medical history
Chest X-ray
Computed tomography (CT) scan

Bronchoscopy
Biopsy

Treatment Options for Lung Cancer

The treatment options for lung cancer depend on the stage of the disease, the type of cancer, and the patient's overall health. Common treatment options include:*
