What is lung cancer?

Lung cancer is a malignant growth of cells in the lung.

You see, throughout life, the division of cells in your body again and again and reproduce. Believe it or not, every minute of your life, this is called ten million times. Think about it … ten million times a minute! This is not only unbelievable, is an example of how complex your body really is.

Well done, for the most part, takes it all in an orderly manner, because the cells to their work, the meetingthe needs of your body. Occasionally, however, a mutation occurs, and then as a cellular aging and death, as it was intended to further increase a cell. This is the cancer … the uncontrolled proliferation and growth of abnormal cells in the body.

Lung cancer is the growth of malignant cells in the lung.

In most cases, the malignant cells are found in the epithelial lining of the respiratory tract, where oxygen in the air we breathe, to be extracted. For this reason,Lung cancer is sometimes referred to as lung cancer (cancer), the bronchi. A relatively small percentage of lung cancer (10% or less) will begin in the pleura, the sac of thin tissue that surrounds the lungs. These tumors are related, such as mesothelioma. The most common form of mesothelioma caused by asbestos. The rarest form begins in the blood vessels or other supporting tissues of the lungs.

Types of lung cancer

There are twoMain types – the small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC).

SCLC is the least common of the two, which is good because it is even more lethal. Less than one percent of SCLC is diagnosed in non-smokers. This means that smoking is the main responsible for this type of lung cancer. SCLC is aggressive and rapidly evolving. E 'metastasizes rapidly to other organs, and is often discovered only when the cancer has already spread throughout the body.

Non-small cellLung cancer accounts for approximately 80% of cases diagnosed with lung cancer. Within this category there are three broken … Squamous cell carcinoma, adenocarcinoma and large cell carcinoma. Sometimes two or even all three together can occur.

Finally, there are some common types, such as bronchial carcinoid tumors (small tumors that are found more commonly in people under 40 years). These tend to be less aggressive, grow slowly and can often be effectivelytreated.

Fatal cancer

Lung cancer is one of the most deadly cancers. This is mainly due to the fact that lung cancer tends to metastasize at an early stage of the disease and often is discovered only when it is widespread. Also, if it does spread, it tends to spread, but the most vulnerable organs of the body. The adrenal glands, liver, brain and bone are all early goals.

Finally, because the lungs are sosusceptible to metastatic cancer from other sources throughout the body, it is not unusual for a cancer found in the lungs, not cancer, but metastatic cancer. These tumors tend to make their homes in the peripheral tissues of the lungs and not the primary fabric.
