In most cases, metastatic cancer to the lung is a sign that the cancer has spread into the bloodstream. Usually cancer will be present even in places not seen by CT scans. In these circumstances, removing the visible tumors by surgery usually is not much, so usually opt for chemotherapy.
Sometimes when the primary tumor has been removed and the cancer has spread to only limited areas of the lung, lung tumors can be removed with surgery. However, the primary tumor should be curable lung tumors must be completely removed and the patient should be strong enough to undergo surgery and recovery.

Lung cancer is one of the most common cancers in the world. It is the leading cause of cancer death among men and women in the United States. Cigarette smoking causes most lung cancers. A greater number of cigarettes they smoke daily newspapers and the younger you start smoking, the greater the risk of developing lung cancer. Exposure to high levels of pollution, radiation and asbestos can also increase the risk.
Common symptoms of lung cancer include:
- A cough that does not go away and worsens over time
- Constant chest pain
- Cough with bloody sputum
- Shortness of breath, wheezing or hoarseness
- Repeated problems with pneumonia or bronchitis

Lung cancer diagnosis is made by radiological examinations: X-ray Computed Tomography and especially (or CAT scanner) Chest, and confirmed with a biopsy.
Only 15 to 20% of lung cancers are detected in its early stages because the symptoms are delayed. In many cases the diagnosis is usually incidental, that is, by medical evidence that you had another purpose. When diagnosed with lung cancer, additional tests are performed to evaluate different tumor stage (if the initial or advanced) as well as lung capacity and general condition.

The lungs are the organs responsible for oxygenating the blood and expel carbon dioxide, a waste product produced by the body’s cells. Also participating in other important metabolic and cardiovascular functions. The bronchi, while carrying the inspired air into the lungs. From the trachea are divided on, giving rise to smaller and smaller bronchi to reach the alveoli. The alveoli are tiny sacs surrounded by small-caliber blood vessels (capillaries). Among the air in the alveoli and capillaries where gas exchange occurs.
The lung cancer is a malignant tumor that usually originates in the cells lining the bronchi (bronchial epithelium). It is produced mainly by irritation and chronic inflammation of the bronchial epithelium by external agents (carcinogens), wherein the cigarette smoke. Proceeds from this chronic irritation and genetic mutations occur that lead to rapid and uncontrolled growth of certain cells, called malignant transformation, thus creating a cancer. Finally when we continue to grow the tumor, some cells may travel to other organs of the body, giving rise to metastases.

The doctor needs to know the stage of the cancer to plan treatment. The classification of lung cancer non-small cell goes through the following stages:
- Step hidden. Cancer cells are found in sputum, but you can not find any tumor in the lung.
- Stage 0. The cancer is localized in one area, in some cell layers only, and no growth through the lining of the lung. Another term for this type of lung cancer is “carcinoma in situ.”
- Stage I. The cancer is found only in the lung and is surrounded by normal tissue. * Stage II The cancer has spread to nearby lymph nodes.

The easiest way to understand the difference between lung cancer and mesothelioma is that lung cancer is in the lung tissue, while pleural mesothelioma occurs in the layer of tissue that covers the outside of the lung.
Smoking is considered the primary cause of lung cancer and asbestos as the primary cause of mesothelioma. Asbestos can also cause lung cancer. Smoking does not cause mesothelioma. People who have been exposed to asbestos and also smoke have up to 90 times more likely to be affected with lung cancer than those who do not smoke.

To determine if a patient has, in effect, of cancer, there is a wide variety of tests that the doctor can use. After the initial examination and x-ray, your doctor might order tests on phlegm. Other tests may include:
Bronchoscopy
It is a procedure designed to look inside the airways of the lungs. It involves inserting a thin, flexible tube down the throat into the airways. The tube allows the doctor to look inside. Your doctor might also take samples of tissues and cells (biopsy) during bronchoscopy.

The culture of organ transplantation in the world both in Mexico and in the World is underrated and little is done to try to promote it, which has led to illegal trafficking in them. Many are in favor of giving life when our bodies we no longer are useful, however the note then I will comment opens the door to an interesting debate.
Lynsey Scott, who suffered from cystic fibrosis, received in February 2009 a double lung transplant from a donor who had smoked for 30 years. Scott died of pneumonia in July, this 28 year old British woman received a lung transplant from a donor smoking without knowing it, and it is precisely this that would like to discuss, because in principle the patient receiving a transplant should know that the national you receive is not entirely new, and the fact that the family found out later that the donor was a smoker does not different, I do not think knowing that Scott had refused to receive the lungs.

An antigen is a foreign substance recognized and marked by the body’s immune system to be destroyed. The antigens are found on the surface of all cells, but usually an individual’s immune system does not react against its own cells. When a cell becomes cancer, new antigens (unfamiliar to the immune system) appears on the surface of this cell and the immune system may consider these new antigens, called Tumor antigens as foreign and is able to stop or destroy these cells cancer. However, even fully operational, the immune system does not always destroy all the cancer cells.
Tumor antigens have been identified in several types of cancer, including malignant melanoma, bone cancer (osteosarcoma) and some types of gastrointestinal cancers. People with these cancers can develop antibodies against these tumor antigens, but antigens usually do not produce an adequate immune response to cancer control. In addition, antibodies may be incapable of destroying the cancer and sometimes even seems to stimulate their growth.

The immune system attacks and eliminates not only bacteria and other foreign substances but also cancer cells. A cancer cell is a cell not strange, it is a cell whose biological function has been altered so that does not meet the body’s normal mechanisms that control the growth and reproduction of it. The abnormal cells can continue to grow, turning into cancer.
In the immune system, a large part of the body’s defense against cancer is carried out directly by cells, rather than by antibodies circulating in the blood. For example, the presence of tumor antigens on cancer cells can activate certain white blood cells (lymphocytes and in a much lesser degree, monocytes) which perform an immune surveillance seeking and destroying cancer cells.
