Lung Cancer is a type of cancer that originates in the lungs. People who smoke have the greatest risk of lung cancer. Typically, lung cancer does not cause any symptoms, only when the disease is in advanced stages symptoms occur. Symptoms are:
• A new cough that does not go away
• Changes in a chronic cough of a smoker
• Coughing blood
• Shortness of breath
• Chest pain
• Losing weight
• Bone pain
HOW IS LUNG CANCER DIAGNOSED?
In order to diagnose lung cancer, the doctor may recommend:
• Imaging tests. An X-ray image of the lungs may reveal an abnormal mass or nodule. A CT scan can reveal small lesions in the lungs that might not be detected on an X-ray.
• Sputum cytology. If one has cough and are producing sputum, looking at the sputum under the microscope can sometimes reveal the presence of lung cancer cells.
• Tissue sample (biopsy). A sample of abnormal cells may be removed in a procedure called a biopsy.
HOW IS LUNG CANCER TREATED?
Treatment of Lung Cancer depends on the severity of disease and the extent to which cancer has spread. Surgical removal of the damaged portion of the lung and a margin of healthy tissue is the first line of treatment. Chemotherapy and radiation therapy are followed for killing the remaining cancer cells.
