Lung cancer is one of the most common types of cancer occurring. Lung cancer is a condition in which cells grow uncontrollably in the lungs.
However, lung cancer is one of the most types of cancer can be prevented. This condition mostly suffered by active and passive smokers.
In the early stages, there are no obvious signs or symptoms of lung cancer. But then symptoms such as a sustained cough to the coughing up of blood, always feeling out of breath, exhaustion for no reason, and weight loss will appear.
Types of Lung Cancer Existing
There are two types of primary lung cancer based on the cell type, namely small-cell lung cancer (SCLC) and non-small-cell lung cancer (NSCLC). Non-small cell lung cancer is four times more likely than small cell lung cancer.
The type of lung cancer small cell (SCLC) usually only afflicts the heavy smoker and its spread faster compared to cancer lung non-small cell (NSCLC).
People At Risk Affected by Lung Cancer
Smoking can be said to be the main cause of lung cancer. People most at risk for lung cancer are active smokers. About 85 percent of lung cancers are associated with smoking habits.
Even so, it does not mean every smoker will get lung cancer. In addition, people who do not smoke are also likely to have stricken with lung cancer, although the lower amount.
Besides smoking, some other causes of lung cancer are inhaling arsenic, radiation, and air pollution. Lung cancer is also more common in elderly people.
Treatment On Lung Cancer
There are several factors that influence the method of treatment and handling which is done to overcome lung cancer are:
1- How severe the spread of cancer.
2- Patient health condition.
3- Types of cancer sufferer.
Cancer removal surgery can be done if cancer cells have not spread widely to other parts of the body. If the health condition is not possible for surgical removal, other ways of handling can be applied. The process of destruction of cancer cells by way of radiotherapy can be run.
Lung cancer generally does not cause symptoms before the cancer cells, spread to large parts of the lungs or to other body parts. Healing depends on the spread of cancer and when cancer diagnosis is known. The earlier the diagnosis is made, the possibility of treatment to succeed also becomes higher.
