What is lung cancer?
Lung cancer is cancer that begins in the lungs. Cancer is a disease in which cancer cell growth goes out of control, taking on the normal cells and organs of the body. There are two main types of lung cancer. Each type grows and spreads in different ways. Nonsmall cell lung cancer. This is the most common type of lung cancer. It usually spreads more slowly than other types of lung cancer. There are three main types of lung cancer:
Squamous cell carcinoma
Adenocarcinoma
Large cancer
Small cell lung cancer
This is a less common type of lung cancer and it spreads faster than non-small cell lung cancer. There are three main types of small cell lung cancer:
Small cancer
Mix in a small cell
Combined small cell lung cancer
Lung cancer is usually vyzvann smoking - but not always. The researchers say that more than 90% of lung cancers in men and at least 70% of women are the direct result of smoking. Lung cancer can also be caused by other things. Some people who have lung cancer have never smoked in my life. Their cancer may be caused by something else, such as:
Second-hand smoke. People who regularly breathe passively, two times greater risk of developing lung cancer than people who stay away from smoke. It is a fact. Radon. Radon is a colorless, odorless gas found in soil. Radon can enter buildings through cracks in the foundation or insulation, or through drains or walls. Radon gas can get trapped in basements and other places that do not have a lot of air (fresh air). People who have high exposure to radon are at higher risk is also a cause of lung cancer.
Asbestos. Asbestos is heat-resistant mineral used in construction. It was also used in brake pads, insulation. People who have high exposure to asbestos have a higher risk of lung cancer.
Other toxic products of uranium, arsenic, some petroleum products may also increase the risk of lung cancer
Who is at risk?
People who are exposed to these things are most at risk of lung cancer:
Cigarette smoking
Second-hand smoke
Being exposed to asbestos or radon
Or a combination of any of these risks
If you smoke and you are exposed to another risk factor (radon, asbestos, etc.) you are at much higher risk of developing lung cancer.
As you can reduce your risk?
The best way to reduce the risk of lung cancer is simple: do not smoke. If you smoke, quit. The sooner you quit smoking, the sooner your risk of lung cancer is reduced. It's never too late to quit smoking. Stay away from secondhand smoke. Test your home for radon, which can penetrate through walls and basements.
