Our lung is one of the main "engines" of our body. But it is often not given the necessary attention and care, and remain in the background when it comes to matters of the heart or brain.

The main function of our lungs, gases between the air we breathe and our exchange of blood. And 'through our lung that carbon dioxide is emptied from our body and oxygen is transported to our blood vessels. Is not generally known that the two sides of the lungs are not identical. Theright lung has three sides, while the left lung has two bedrooms and an extra helping, called the lingula that as the middle lobe.

Lung cancer is the main form of cancer death among men and women in the world. It is only since 1930 that cases of lung cancer begins to rise. This is mainly due to tobacco consumption, and pollution and smog highly controversial worldwide. 90% of lung cancers caused by smoking. Recently, governments and statesWorldwide, the price of tobacco dramatically, with significant impact on communities in reducing tobacco smoking.

Some people mistakenly believe that pipe and cigar smoking has a deleterious effect on the lungs than cigarettes. Cigars and pipe tobacco are 5% higher risk of dying from lung cancer than nonsmokers. This ratio is 25% for people who smoke cigarettes.

passive smokers, ie smokers who do not smoke, but live in an environmentwhere others smoke smoke are 24% higher risk of developing cancer (only 1% smaller than a cigarette smoker).

Other risk factors in the development of cancer are asbestos, radon gas, family history (genetic) and other lung diseases, along with air pollution.

Lung cancer is divided into two types. small cell and non-small cell lung cancer. This distinction is based on the appearance of cells by microscopic examination and prevention of cancercells. The two types of cancer spread and growth in different ways, so the distinction.

Small cell lung cancer is the most aggressive and rapidly growing form of cancer, and opens up to 20% of tumors. It tends to grow only in the larger breathing tubes and grows rapidly spread over a wide area. In its first phase, is more sensitive to chemotherapy and is often worn worse prognosis. This type of cancer is mainly related to smoking.

On the other hand,non-small cell lung cancer, the prognosis is poor. Patients treated with chemotherapy life in general, only three months longer than those not receiving treatment. This type is further divided into two types, one of the effects of breathing tubes larger, but slower to spread. This means that the size of these tumors varies when diagnosed. 50-60% of non-small lung cancer begins to grow on the surface of the lungs for gas exchange. This form is the most common for smokers, and next to thatwere female non-smokers who are mainly concerned.

Our lung is an organ very sensitive, often landing metastasis (when cancer cells break away from the primary tumor) of cancer from other parts of the body. In this case we call this the origin of the body, including breast cancer.

Cancer is a disease clever. Women can develop cancer of ovarian origin of stomach cancer. Affects the most innocent, the best sports, the firmestvegetarian, all without mercy. If this is your lungs, it takes your breath away. Do not have a chance.
