Lung Cancer
Smoking causes most cases of lung cancer. If you smoke, your risk of lung cancer increases according to the length of time you smoke. Second -hand smoke also increases your risk of lung cancer. Signs of lung cancer include persistent cough, weight loss, shortness of breath, coughing up blood, chest pain, or a hoarse voice. If lung cancer if suspected, doctors may begin their examination by exam
If diagnostic test show cancer, doctors identify the type of lung cell from which the cancer developed. inating a patients coughed up materials for cancer cells. The lining of a normal bronchus is composed of various kinds of cells. Most cases of lung cancer start in tissue that lines the brongh, (which is the tubes that supply the lungs with air). Few patients whose cancer has spread can be cured. The different types of cells respond differently to treatments. Patients may also have a chest x-ray to reveal suspicious masses or other signs of lung disease. One of the functions is to get rid of the mucus from the lungs. During the surgery, doctors also remove lymph nodes and test them for cancer cells. Lung cancer like all other forms of cancer, results from uncontrolled cell growth. Treatment of these patients need to extend life and reduce pain. Doctors can sometimes cure patients whose cancer has not spread. If cancer appears confined to the lung and the patient is healthy, surgeons usually remove all or part of the lung. Doctors may prescribe drug treatments to try to shrink tumors and relieve symptoms.
