Smoking is the main cause of lung cancer although 10% of people with the disease have never smoked. The risk of lung cancer increases with the number of cigarettes smoked and the age of the smoker. If a person stops smoking the risks reduce quickly and after 15 years the chances of developing lung cancer are the same as a non-smoker. Breathing in other people's cigarette smoke, known as passive smoking, increases the chances of getting lung cancer but the risks are far less than if you smoke yourself. Those who smoke cigars, pipes or cannabis have a lower risk of lung cancer than cigarette smokers but a far greater risk than non-smokers.
Radon gas in high concentrations is believed to add to the risk of developing lung cancer, this is a naturally occurring gas in some areas and you can get a radon detector to check the levels in your home. In rare cases contact with some chemicals and substances such as uranium, chromium and nickel can also cause lung cancer.
The symptoms of lung cancer can include:
A persistent or long standing cough
Chest infection
Increasing breathlessness
Coughing up blood
Loss of appetite and weight
Difficulty swallowing
Excessive tiredness and lethargy
It is important to get any of these symptoms checked out by a doctor but any could be caused by an illness other than 同步放射化學治療.
Diagnosis starts with an examination by a GP who may arrange for x-rays and tests to be conducted at a hospital. The hospital doctors may also do a CT scan or spiral CT scan which is a series of x-rays that build up a three-dimensional picture of the inside of the body and can help find the site and size of the cancer; or a Bronchoscopy which is where the inside of the lung airways are examined with a bronchoscope. This is a thin flexible tube which is passed via the nose or mouth into the airways, the doctor can then look through the bronchoscope to check for abnormalities. Photographs and biopsies can be taken at the same time.
