 | Overview |
| | The cells of all living organisms normally divide and grow in a controlled manner. Cancer results when this control process is lost. A lump or tumour, known as the primary tumour can grow locally or spread to produce secondary tumours somewhere else in the body. This spreading process is called metastasis. Lung cancer is a malignant tumor of the lungs. There are many types of lung cancer, but most can be categorized into two basic types, "small cell" and "non-small cell." Small cell lung cancer is generally faster growing than non-small cell, but more likely to respond to chemotherapy. There are several different subtypes of non-small cell lung cancer -- adenocarcioma, squamous cell carcinoma, and large cell carcinoma. However, the outlook is similar for these subtypes and they are treated the same. Non-small cell cancer is divided into four stages, I-IV. |

| Causes |
| | Tobacco smoke is the primary cause of lung cancer. Although nonsmokers can get lung cancer, the risk is about 10 times greater for smokers and is also increased by the number of cigarettes smoked per day. If you are a heavy smoker consuming more than 20 cigarettes a day, the risk of developing lung cancer is about 30 to 40 times higher than if you don't smoke. The main reason for the substantial increase in the disease over the last 50 years has been the increase in the number of people who smoke cigarettes. This has resulted from the industrial production and marketing of tobacco. The risk of lung cancer in an ex-smoker falls to the same level as a nonsmoker after about 15 years. Most lung cancers are caused by cigarette smoking. The more cigarettes you smoke per day and the earlier you started smoking, the greater the risk of lung cancer. Second-hand smoke has also been shown to increase risk. Government surveys show that as many as 3,000 people each year develop lung cancer from second-hand smoke. High levels of pollution, radiation, and asbestos exposure may also increase risk. |

| Symptoms |
| | The symptoms of lung cancer include: - a chronic cough.
- worsening breathlessness.
- weight loss.
- excessive fatigue.
- persistent pain in the chest or elsewhere, (possibly from the cancer spreading to a bone).
- symptoms can be due to the original tumour in the lung or to the effects of secondary tumours elsewhere in the body.
- bone of the most significant symptoms of lung cancer is coughing up blood or haemoptysis. This can sometimes occur as an early warning sign of a cancer which may still be curable. Any person who coughs up blood should see their GP for advice urgently as lung cancer must be considered, particularly if the person is a smoker over the age of 40.
