The deaths of patients diagnosed with lung cancer through the scanner are 20% lower than among those who are detected X-ray disease, said the National Cancer Institute U.S.

The agency posted on its website the preliminary results of a national study on the disease that took eight years and have participated in 53.000 smokers aged 55 to 74 years.

Eating a wide variety of fruits and vegetables may help protect some smokers from lung cancer, a European study.

But researchers emphasized that quitting smoking do more to reduce the risk of “an apple a day” or with a salad for lunch.

Most lung cancer begins in the lining of the bronchi, the tubes in which the trachea or windpipe divides. However, asbestos lung cancer can also begin in other areas such as the trachea, bronchioles (small branches of the bronchi) or alveoli (air sacs in the lungs). Although lung cancer usually develops slowly, when this occurs, cancer cells can break away and spread to other parts of the body.

The two most common types of lung cancer are small cell lung cancer (SCLC), in which cancer cells are small and round, and the cancer non-small cell lung cancer (NSCLC), in which cells are larger cancerous. Sometimes, a cancer has characteristics of both types, and is called mixed small cell and large cell cancer.

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.

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.

The truth is that smokers now and before, and non smokers are protected to varying degrees against lung cancer by eating more vegetables and other foods known for their power to prevent the disease.

Still, many researchers prefer not to mention it, not to downplay the dangers of smoking.

What if you never smoked? eat as directed. ‘can also save from lung cancer in non smokers.
