Cancer lung

Cancer lung is a type of cancer that starts in the lungs, typically due to long-term exposure to carcinogenic substances, such as tobacco smoke. It is the leading cause of cancer-related death worldwide. Cancer lung is caused by the uncontrolled growth of abnormal cells in the lungs. The abnormal cells form a tumor and can spread to other organs. The cancer can spread by invading surrounding tissue or by traveling through the bloodstream or lymphatic system to other parts of the body. The primary symptoms of cancer lung are a cough, chest pain, shortness of breath, wheezing, and coughing up blood. These symptoms may be mild at first and can worsen over time. Other symptoms may include weight loss, fatigue, and swelling of the face and neck. Diagnosis of cancer lung is done through imaging tests, such as X-rays, CT scans, and MRI scans. A biopsy may also be done to confirm the diagnosis. Treatment for cancer lung includes surgery, chemotherapy, radiation therapy, and targeted therapy. The type of treatment depends on the stage of the cancer, the patient’s age and overall health, and other factors.
