Lung cancer is the most preventable cancer in the world, and the primary cause is smoking. Stopping smoking is the only way to guarantee that you will be at a lower risk for this type of cancer that generally proves fatal in smokers.
Most lung cancers are of the non-small cell variety, invading the lungs as well as the surrounding tissues. The lining of the bronchi is the first area within the lungs that will be affected. And, there are different behaviors associated with this cancer that help the doctors to determine the exact type of lung cancer acting on affected areas. The determination of the type of lung cancer will make a difference in the plan of treatment prescribed for a particular patient.
In lung cancer patients, overall health is the most crucial factor in determining which combination of treatments will be most effective. Generally, however a combination of therapies is used to get the best success rate. Surgery is common, as are both chemotherapy and radiation. Lung cancer patients are at an advantage because there has been extensive research and testing done on the different treatment options. This information provides the patient with a better chance of survival now than ever before.
There are other causes for lung cancer besides for smoking. Second hand smoke inhalation, environmental pollutants and other things can all contribute to a person’s risk for developing lung cancer.
The two varieties of lung cancer that are the most commonly occurring are small cell carcinoma and non-small cell cancers. Small cell carcinoma is much less common, amounting to about 20% of diagnosed cases.
Non-small cell Lung Cancer:
This type of lung cancer is slow developing in comparison to small cell cancers. There are three sub-types of non-small cell cancer of the lungs. These are large cell carcinoma, Adenocarcinoma and Squamos cell.
Small-cell lung cancer:
We mentioned earlier that small cell cancer accounts for only about 20% of lung cancer diagnoses. This type of cancer is rapid-spreading and tends to most commonly come back at a later point in the patients life as a recurrence, Small cell cancer also tends to metastasize, particularly to the brain, in many patients.
Heavy smokers in particular, should be tested frequently to ensure that cancer has not developed within the lungs. The sooner cancer is detected, the better the chance of survival. Quitting smoking is the best defense against developing any type of lung cancer.
