Lung cancer is a dangerous disease with a high mortality rate. However, if the disease is diagnosed and treated early, the prognosis is quite good. Currently, there are many methods to diagnose lung cancer such as computed tomography, PET, brain MRI/CT, biopsy, endobronchial ultrasound. Treatment options depend on the severity of the disease, including surgery, radiotherapy and systemic therapy or a combination of methods.

Diagnosis of chronic obstructive pulmonary disease (COPD) will be based on signs and symptoms, or a history of exposure to lung irritants (such as smoking) and family history. However, to have accurate results before making a definitive diagnosis and treatment prognosis, the doctor needs to conduct some imaging tests such as lung CT scan, lung MRI and other tests if necessary.
