But some cells escape the immune system and grow out of control, forming a tumor in the lung. Also, exposure to certain chemicals, gases or pollutants over time may increase the risk of developing lung cancer.
Risk by age: About two out of three lung cancers are diagnosed in people over age 65, and most people are older than The average age at diagnosis is Family history: Genetics may predispose certain people to lung cancer. Individuals with an immediate family member who has or had lung cancer and who does not or did not smoke may be more prone to developing the disease.
Smoking and secondhand smoke : Smoking is widely considered the leading cause of lung cancer. The National Cancer Institute NCI reports that tobacco smoking causes about nine in 10 cases of lung cancer in men and eight in 10 in women. Exposure to asbestos or other pollutants: Carcinogenic chemicals in the workplace increase lung cancer risk, especially if you smoke. Exposure to radon: Radon is a colorless, scent-less radioactive gas that is found in some houses and is a leading cause of lung cancer.
Some evidence points toward a genetic link in a few cases. Tobacco use: Smoking tobacco cigarettes, pipes or cigars is linked to more than four out of five cases of all lung cancers. Heavy smokers and those who began smoking at a young age are at an increased risk of developing the disease. It is possible to significantly reduce the risk of lung cancer if you stop smoking. According to the U. Centers for Disease Control and Prevention, cigarette smokers are 15 to 30 times more likely to develop lung cancer than non-smokers, and smoking is linked to an estimated 80 percent to 90 percent of lung cancer deaths.
Radon gas: A naturally occurring odorless gas, radon may be found in some houses or buildings. The U. Environmental Protection Agency considers exposure to radon gas as the number one cause of lung cancer in non-smokers. Kits are available to test for radon in your home or office. Asbestos : Long-term exposure to asbestos is linked to an increased risk of lung cancer. Miners, mill workers or people who may have breathed in asbestos fibers are at a greater risk of developing lung cancer.
However, some lung cancers aren't diagnosed until they are quite advanced. This means you cannot cure the cancer, but you may be able to help control its symptoms. Caring for someone with cancer can be a difficult and emotional time.
If you or someone you know is caring for someone with lung cancer, they may find it helpful to download and read some of the Cancer Council Victoria information booklets.

Aspergillus is a fungus that commonly grows on rotting vegetation. It can cause asthma symptoms. Asthma cannot be cured, but with good management people with asthma can lead normal, active lives. Before a biopsy, you need to discuss a range of issues with your doctor or surgeon.

Different types of lung cancer Lung cancer in non-smokers Non-tobacco risk factors for lung cancer Symptoms of lung cancer Diagnosis of lung cancer Treatment of lung cancer When a cure isn't possible Caring for someone with cancer Where to get help.
Different types of lung cancer A cancer that starts in the cells lining an organ is known as a carcinoma. The two main types are: Small cell carcinoma or 'oat cell' carcinoma, named after its cell shape.
Around 15 per cent of lung cancers are small cell carcinomas. This type of cancer spreads early, shows few early symptoms and is strongly linked with cigarette smoking Non-small cell carcinoma — these cancers affect the cells that line the main bronchi airway passages into the lungs. Different types of non-small cell cancer Some of the different types of non-small cell cancer include: squamous cell carcinoma — generally discovered earlier than other lung cancers and has the best outcome after treatment adenocarcinoma — now the most common type in both men and women.
Its rise may be related to changing patterns of smoking, including the use of filtered cigarettes large cell carcinoma — named for its large, rounded cells visible under the microscope.
It is sometimes known as 'undifferentiated carcinoma' bronchiolo-alveolar cell carcinoma — one of the less common types of cancer.
Lung cancer in non-smokers A small percentage of non-smokers develop lung cancer even though they have never smoked and are rarely exposed to smoky environments. Non-tobacco risk factors for lung cancer Cancer is a complex disease caused by a mix of genetic and environmental factors. Apart from passive smoking, some of the factors that may increase the risk of lung cancer in non-smokers include: gender — non-smoking women seem to be at increased risk compared to non-smoking men.
Researchers suggest that sex hormones may play a role smog — air pollution contains many cancer-causing agents carcinogens wood smoke — exposure to wood smoke for several hours every day for example, burning wood for heating and cooking can cause lung cancer in non-smokers.
Wood smoke contains many of the carcinogens found in tobacco smoke asbestos — people who worked with asbestos are about seven times more likely to develop lung cancer than the rest of the population.
The most common type of cancer caused by asbestos exposure is mesothelioma, which grows in the membrane sac pleura that encases the lungs workplace carcinogens — exposure to chemicals found in some workplaces can increase the risk of lung cancer.
