Malignant neoplasms of the bronchus or lung are the leading cause of cancer-related death in both men and women worldwide. Risk factors for developing lung cancer include smoking, exposure to second-hand smoke, and exposure to certain carcinogens, such as asbestos, radon, and certain chemicals.
Diagnosis of lung cancer can be made with imaging studies such as chest X-ray, CT scan, and PET scan, as well as through biopsy of a tissue sample.
Other conditions that can present with similar symptoms include asthma, pneumonia, and bronchitis.
Treatment for lung cancer can include surgery, chemotherapy, and radiation therapy.
The prognosis for lung cancer varies depending on the stage at diagnosis and other factors. Early diagnosis and treatment can improve the prognosis for a patient with lung cancer.
