Each year in the United States alone, about 170,000 people die of lung cancer. Cigarette smoke is considered the biggest culprit as the main cause of lung cancer for both smokers and non smokers alike. For the most part, lung cancer can be prevented, due to the fact it may take years for the cancer to develop.
Besides tobacco as being the number one cause of lung cancer, some other causes can be from cancer causing agents in the workplace, or family and /or personal history of lung cancer.
The main cause for lung cancer from genetics is because of the DNA mutations in the genes that activate the cell dividing genes, and the DNA mutations in the genes that inactivate the tumor suppressing genes.
Another cause of lung cancer is asbestos. A person exposed to asbestos is about 50 to 90 times more likely to get cancer than those persons not exposed are. Fortunately, the government has put a ban on the use of asbestos.
House that are built on soil rich in uranium will more than likely have the presence of radon gas. You can purchase a radon detector to determine if your house shows any levels of radon anywhere.
Other causes attributing to the cause of lung cancer are:
* Gasoline smell
* Diesel exhaust
* Mustard gas
* Vinyl chloride
* Coal products
* Beryllium and more
Marijuana has a greater amount of tar than regular cigarettes. Marijuana is breathed in deeply and kept in the lungs, thereby posing a greater health risk. Marijuana is also a contributor to both throat and mouth cancer.
Not only is it important to know the cases of lung cancer, it is equally important to know the symptoms. If you are experiencing one or more of the following symptoms, you should contact your doctor just to be on the safe side.

You may need to undergo tests, but it will be well worth your state of mind to know what is or what is not posing a problem to your health. From the results of those tests, you and your doctor will be able to determine what path, if any, to go from there.
