"Sadly an increasing number of Australians are paying the price for taking up smoking at a time when tobacco companies ruthlessly marketed their products as a socially acceptable habit. For smokers today the proven link to lung cancer makes it more important than ever to consider your future health and wellbeing by quitting smoking. If you're thinking about stopping smoking, talk to your doctor or call 13QUIT - getting help will significantly improve your chances of success." Dr Christine Bennett, Chair, Medical Advisory Panel, Bupa Australia
Lung cancer is cancer of some cells in part of the lung. It usually starts in the lining of an airway.
There are different types of lung cancer, classified by the type of cell affected. There are two main types-small cell lung cancer and non-small cell lung cancer.
Small cell lung cancer makes up around 15 percent of lung cancers and is strongly linked with smoking. It tends to start in the middle of the lungs. Because it usually spreads early after it forms, surgery isn't often used for this type of cancer. Instead it's best treated with drugs (chemotherapy), often combined with radiotherapy.1,2
Non-small cell lung cancers affect the cells that line the main bronchi (the tubes into the lungs) and the smaller airways.2,3
Common symptoms of lung cancer include:1,2,3
Because most of these symptoms are common in smokers who become used to them, people tend to report little more than tiredness and weight loss to their doctor before they're diagnosed with lung cancer.
Lung cancer is the most common cause of death from cancer in Australia.4
Up to 90 percent of lung cancer cases are caused by smoking.2 The incidence of lung cancer relates in part to the high number of people who smoked during a time when cigarettes were sold with little or no curbs on tobacco marketing. Even so, a high percentage of people still take up smoking or continue to smoke, despite the large amount of evidence linking smoking to lung cancer and various other long-term health conditions.
As with many other types of cancer, the cause of lung cancer is not always known. Cigarette smoking is the major cause of lung cancer with 10 percent of smokers developing the disease1. Why one smoker may develop lung cancer while another won't still isn't clear, but the younger someone starts smoking, the higher their risk of getting lung cancer.
Other risk factors include:5
The lung cancer treatment you receive will be based on a number of things including your overall health, the type and stage of your cancer, and your own preferences.
You would typically have one or more treatments including surgery, chemotherapy, radiation therapy or targeted drug therapy.1,2,3
Yes. But quitting at any age can significantly lower your risk of developing lung cancer. Your risk of lung cancer increases with the number of cigarettes you smoke each day and the number of years you've smoked. 2,5
