Lung cancer is a serious health problem, it is essentially the growth of abnormal cells in the lungs.
This growth of unhealthy cells can start anywhere in the lungs.
Lung cancer is actually the leading cause of cancer deaths in both men and women. Of those people who contract lung cancer, less than half of them survive one year. The quicker you notice symptom and have it diagnosed, the quicker treatment can begin and the odds improve.
The leading cause of lung cancer is smoking. eighty seven percent of people who have lung cancer have gotten it from smoking.
If a person smokes a pack a day, they have twenty times the risk of getting lung cancer or some other serious health problem than a person who doesn't smoke at all.
There are so many carcinogens in tobacco smoke that they constantly damage the healthy cells of the lungs, and the risk goes up for smokers depending on how long they have smoked and how much they have smoked.
There are other causes of lung cancer for healthy people who don't smoke
These causes include asbestos, which used to be used in building materials. It enters a healthy person's lungs by inhaling, and then attaches to the respiratory lining.
People who get lung cancer from asbestos exposure usually get it from work or from living in an older home.
Some doctors also think that women who are exposed to tobacco smoke, are more likely to have lung cancer than men exposed to smoke. Researchers have found a gene called GRPR which causes unusual cell growth in people exposed to cigarette smoke. This gene is more active in women than in men and may explain why females are more prone to lung cancer.
Some research has indicated a diet low in fruit and vegetables may increase the chances of developing cancer if exposed to tobacco smoke. Some evidence shows fruit and vegetables may protect against lung cancer.
The final cause of lung cancer in healthy people is radon exposure.
Radon is a gas which is naturally released from soil and rocks. In closed spaces like caves, basements and other areas, it can become concentrated and cause lung cancer or other health problems. It is always a good idea to have a home checked for radon levels because there are things that can be done to lower them to more acceptable levels.
The good news?
When smokers quit smoking, their risk for getting lung cancer goes down immediately and every year that they don't smoke.
It is also an interesting fact that 25% of nonsmokers that get lung cancer live with smokers, so the secondhand smoke is most likely the cause of their lung cancer health issues.
