Deadly Lung Cancer A common type of cancer is lung cancer, which begins with DNA mutation and uncontrolled growth of mutated cells in at least one lung. These mutations are caused by factors including breathing cigarette smoke and exposure to radon gas. As the name suggests, lung cancer affects the lungs. It can potentially spread from one part of one lung to cover both lungs if malignant tumors are present. Lung cancer is more common in people over the age of sixty, but can sometimes start years earlier. There are four stages of lung cancer. In stage I, cancer is present only in the lungs. In stage II, the cancer spreads to the lymph nodes. In stage III, the cancer spreads to the lymph nodes in the central part of the chest. In stage IV, the cancer has spread completely to both lungs or to another organ. Say no to plagiarism. Get a tailor-made essay on "Why Violent Video Games Shouldn't Be Banned"?

A similar symptom that may be present is coughing up blood. Other symptoms include a change in the color of the patient's mucus, shortness of breath, difficulty breathing and swallowing, and pain in the chest, shoulder and/or back. There are also several symptoms that spread to the rest of the body. These include weight loss, fatigue, memory loss, bleeding, bone pain, fever, and general weakness. Fortunately, there are many methods of treating lung cancer. These methods include chemotherapy, radiation therapy, and surgery. In chemotherapy, chemicals are injected into the body to kill actively dividing cells in all parts of the body. In radiation therapy, radiation is used to kill cancer cells and shrink tumors in one part of the body by preventing the cells from dividing. Surgery is often used in the first two stages of lung cancer to remove the lobe of the lung that contains the tumor. Although lung cancer is the leading cause of cancer death in the United States, it remains a possibility of survival for patients suffering from it. The survival rate of patients with lung cancer located in the lungs is 52.6%. Unfortunately, the survival rate of patients with lung cancer that has spread to other organs is only 3.5%. Because of these statistics, it is important that patients who have recently been diagnosed with lung cancer seek immediate treatment. Please note: this is just an example.
