What is lung cancer

Lung cancer is the first cause of mortality as a result of the cancer, whether women or men. Lung cancer signs a number of victims annually, far more than the impact of colon cancer, prostate cancer, cancer of the lymph nodes and breast cancer together.

However, you can prevent most of the deaths from lung cancer, smoking is responsible for nearly 90 percent of all lung cancer cases. And the risk of lung cancer increases steadily as the years and the number of cigarettes that are smoked.

To quit smoking, even after smoking for many years, it can reduce the risk of lung cancer. You can also reduce the risk of lung cancer by avoiding exposure to other factors causing lung cancer, such as exposure to asbestos (Asbestos), radon and secondhand smoke.

Symptoms of lung cancer

Lung cancer symptoms do not appear in the initial stages in most cases. And often show symptoms of lung cancer only when the disease has reached an advanced stage.

Lung cancer symptoms include:

Cough noob, appears and does not disappear

Changes in existing or chronic cough in smokers cough

Cough accompanied by phlegm, bloody, even if a bit too

Shortness of breath

Pain in the chest

Whistling when breathing

Hoarseness

Causes and risk factors for lung cancer

Starts and a lung cancer, usually in the cells that make up the lining of the lungs (the pleura-Pleura). Smoking is the main cause of lung cancer in people smoking, as well as in people who are exposed to secondhand smoke. But lung cancer can hit, too, people who were not exposed to cigarette smoke at all. In these cases, there is, at times, apparent reason for lung cancer. Doctors have succeeded in developing a list of factors that increase the risk of lung cancer.

How smoking causes lung cancer?

Doctors believe that smoking causes lung cancer by infecting the cells that form the inner lining of the lungs. When inhaled cigarette smoke, which contains many substances identified as carcinogens (cancer-causing Carcinogen), changes in the tissues of the lungs, almost instantly. The body is still able to tackle and repair the damage, in the beginning.

But after repeated exposure to these substances, damage healthy cells that form the lining of the lungs, is continuously growing. Over time, the damage to these cells to behave abnormally until, eventually, a cancerous tumor.

The lungs contain many blood vessels and lymphatic vessels, which allows cancer cells transit and move and then easily access to other organs in the body. Therefore, the spread of lung cancer and other organs in the body before they show any symptoms. It is possible that lung cancer spreads, in most cases, even before the note in the lungs themselves.

Types of lung cancer:

Doctors tend to divide into two main types of lung cancer, according to a cancer cell, it seems its under the microscope. On the basis of this Division takes decisions on doctors treatment appropriate in each case.

There are two main types of lung cancer:

Small cell lung cancer (Small cell lung cancer): small cell lung cancer is called also malignant tumor (Carcinoma-Carcinoma) spike-shaped oats. It shows, in most cases, when smoking heavily, and is less common than the second type named "lung cancer-non-small cell".

Lung cancer, non-small cell (Non-small cell lung cancer): lung cancer-non-small cell is a common name of many types of lung cancers that behave uniformly. Includes lung cancer-non-small cell: squamous carcinoma planning (Squamos cell carcinoma), adeno-squamous Carcinoma (Adenocarcinoma) large walsrtanh cells.

There are many risk factors that increase the risk of lung cancer. Some of these risk factors are under human control and control, smoking cessation, for example. In contrast, there are several other factors that cannot be controlled and controlled, such as gender.

Risk factors for lung cancer:

Smoking-smoking remains the main risk factor for lung cancer. The risk of lung cancer increases with increasing the amount of cigarettes smoked per day, with the number of years that have been smoking. Stop smoking, at any stage of life, can reduce the risk of lung cancer, to a large extent.

Gender-women who smoke or who have smoked in the past, are more susceptible to lung cancer than men who smoke the same amount of cigarettes. Although it is not entirely clear, but some experts say that women are more vulnerable to infection and more sensitive to cancer-stimulating substances found in tobacco. In contrast, others believe that estrogen (Estrogen) plays a role. It is also known that women tend often inhaled more deeply than men, and that the chances of drop smoking less.

Exposure to secondhand smoke-the risk of a non-smoker lung cancer increases when exposed to secondhand smoke.

Exposure to radon-radon is produced by natural decay of uranium in soil, rock or water, and eventually turns into one of the vehicles, the air we breathe. Although the exceptional levels of radon can accumulate in any building, but more serious exposure to radon is, essentially,
