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 snuff is the main risk factor. Also influenced by other external actors such as exposure to carcinogens such as asbestos, other minerals and radioactive gases, marijuana use, environmental pollution and recurrent inflammation of tuberculosis and some types of pneumonia, among others. There is also an important genetic predisposition that makes some people more likely to develop cancer when exposed to these carcinogens or even without exposure.

• 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.
• Stage III. The cancer has spread to the chest wall or diaphragm near the lung, or the cancer has spread to lymph nodes in the area that separates the two lungs (mediastinum) lymph nodes or across the chest, or neck.
• Stage IV. The cancer has spread to other parts of the body. Recurrent cancer has returned after being treated.

In the classification of lung cancer small cell stage talks that follow:

• Limited Stage Cancer is found only in one lung and nearby lymph nodes.
• Extensive Stage Cancer has spread outside the lung where it originated to other tissues of the chest or other body parts.
• Step appellant. The disease has recurred after being treated, whether in the lungs or other body part.
• Step appellant. The disease has recurred after being treated, whether in the lungs or other body part.

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.

Some of the symptoms of lung cancer are similar to the symptoms of mesothelioma. Lung cancer cell carcinoma and small cell cancer can cause symptoms such as cough, shortness of breath, bloody sputum, chest pain and wheezing. Adenocarcinomas are most common on the outside of the lung and can cause pain in the chest when breathing, coughing and breathing problems. Sometimes there are patients who have no symptoms when the disease is first detected through a chest x-ray.

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.

True, the donor was a smoker, but also had to be true that state encotraban lungs sufficiently acceptable to be transplanted. I believe that death was in the way of Scott and sooner or later was going to achieve, but from my point of view it would not help the patient to receive more information on the life led by the donor when a transplant itself represents life expectancy.

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

Indeed, some studies indicate that the biggest beneficiaries of the vegetables are those who still smoke or have stopped recently. I recommend reading the article (the lung cancer and vegetables and beans)

A study in Hawaii found that the vegetables had a greater protective effect in men who smoked too much or who had stopped doing so recently, and some women who smoked or had smoked for a long time.

Other studies show that fruits and vegetables to benefit much more ex-smokers, but even those who still smoke derive a high degree of protection.

Of course this does not mean that you should focus on eating large quantities of vegetables for continuing to smoke with impunity, with the futile hope that the remedy of nature save him from a future lung cancer. I recommend reading the article (the lung cancer is prevented by consuming a bit of carotene daily)

The most important and effective is to stop smoking. There is no way that diet can fully compensate the damage that occurs when you fill your lungs with smoke. Even the most fervent anti-cancer vegetable consumers who continue to smoke are ten times more prone to lung cancer than non smokers, according to a specialist.

However, if you insist on smoking, it is highly desirable to devote to eating fruits and vegetables to reduce the risk as possible.

Those who have quit smoking should be aware that these foods accelerate the recovery process by cleaning the lung tissue and soon eliminate the threat of cancer.

The constant intake of antioxidants and anticancer agents can help to interrupt the long, slow path to lung cancer that lasted for years after a person has quit smoking.

Investigations by Richard Shekelle, Ph.D., University of Texas at Houston, found that even men who had long been smoking for thirty years, some could find salvation in vegetables. I recommend reading the article (to prevent lung cancer, avoid low levels of beta carotene daily)

The risk of lung cancer was seven times higher among those who consumed the least amount of foods with beta carotene, compared with those who ate the most.

A diet relatively rich in beta carotene may reduce the risk of lung cancer even among people who have smoked for many years. ” – Richard Shekelle, Ph.D., University of Texas (Houston).

In a group of passive smokers (exposed to smoke of others) of New Jersey, the cancer risk was reduced by almost half with an additional cup of orange vegetables every day.

In another study, researchers analyzed a group of eighty-eight women from Hong Kong, including many who, despite not having ever smoked, had lung cancer. Some foods provide a high degree of protection against lung tumors, especially green leafy vegetables, carrots, tofu and other soy products, fresh fruits and fresh fish. I recommend reading the article (here a wonderful antidote to prevent lung cancer)

Also in that study vegetables exerted a profound effect. Women who ate the most carrots, green leafy vegetables and fresh fruits reduced their chances of getting cancer by 90%, 70% and 40% respectively.

The most common symptoms are usually shortness of breath, cough, including coughing up blood, weight loss, chest pain, hoarseness and swelling in the neck and face, among others.

The most common cause of lung cancer is smoking and people who do not have this habit, the development of cancer is usually a result of genetic factors and exposure to radon (chemical element), asbestos (fibrous metamorphic mineral), and pollution air pollution, including secondhand smoke (passive smoking).

Among the treatment options for lung cancer non-small cell, which is the most common type (it is estimated that approximately 80% of cases, as shown on page www.info.cancerresearchuk.org) AstraZeneca developed a molecular therapy with major advantages over chemotherapy.

Recently, the molecule Gefitinib proved as effective as chemotherapy most widely used second-line treatment with the advantage that produces no side-effects of these therapies such as general deterioration of the patient, nausea, vomiting, hair loss and decrease in white blood cells, causing a predisposition to infection.

The molecule Gefitinib does give better quality of life for the patient with lung cancer and is considered a “treatment directed”, ie that its mechanism of action operates directly on cancer cells without affecting the proper functioning of the organism, preventing the spread of the disease and related mechanisms that blocks the growth, proliferation and spread of cancer. It also has a simple oral administration which facilitates the adherence by the patient to cancer treatment.

It is vital that the individual together with a physician to explore all available alternatives for the treatment of this disease and help make a better choice for that cancer does not thrive without affecting the quality of life of patients.

Unfortunately, often the diagnosis is made too late, and for this main reason about 85 percent of people who become ill end up dying from this cause within a period not exceeding five years.

In the United States, for example, and according to the Lung Cancer Alliance, this type of cancer last year has killed more than 160,300 people, or about 440 a day. For this reason, it is necessary to emphasize the need to prevent: and one of the main ways is to avoid smoking, or who already have a bad habit, you stop.

This need is also based on another key finding: according to the National Cancer Institute of the United States, 90 percent of deaths occur in cases in which smoking is directly responsible for the emergence and development of the lung disease.

For this reason, and although researchers and scientists from around the world try to find better ways to detect lung cancer and to establish the genetic warning signs or markers that people have a greater chance of developing this disease, doctors say snuff action against the principal and have proved but only effective weapon against this cancer so deadly.

Among other measures you can take, experts emphasize the role of nutrition: Dr. Gonzalo Recondo, head of the Department of Clinical Oncology CEMIC Medicine said that “the diet influences cancer development not only for nutrients but also by the fat content and the amount of food you eat. ”

On the consumption of vegetables, the specialist said, “are very relevant for the specific nutrients that help reduce the risk of developing tumors of various types of cancers, including lung, prostate, breast and Pancreas.”

There are two main types of lung cancer: non-small lung cancer cell (or non-small) and small cell (or microcytic). The term “small cell” refers to the size and shape of cancer cells as seen under the microscope. Non-smal lung cancer cell originates in the epithelial cells and is the most common type. Lung cancer begins small cell in the nerve cells or hormone-producing cells.

Each of these types of lung cancer grows and spreads differently, and each requires a different treatment. It is therefore important to find out what type of lung cancer a person has to apply the appropriate treatment.

Once the malignant lung tumor begins to grow, it is possible that cancer cells detach. These detached cells can be transported by the blood or lymph. When a cancer cell is apparent from its place of origin and moves to a lymph node or to a distant part of the body through the bloodstream, and there starts to split and form new tumors, we say that the tumor because distant metastases, has metastasized. We then say that the patient has a cancer then spread, with metastatic cancer.

The lymph flows through tubes called lymphatic vessels that drain into a “collecting stations, lymph nodes, found in the lungs (around bronchi) in the center of the chest (mediastinum) and other body parts. The natural flow of lymph from the lungs is toward the center of the chest, which explains why lung cancer often spreads to there.

When lung cancer cells reach the lymph nodes, can continue to grow. If tumor cells have multiplied in the lymph nodes, you may also have spread to other body parts. For this reason, one of the most decision-making in the treatment of lung cancer is based on whether the cancer has spread to lymph nodes in the mediastinum or not.

The location and size of the initial lung tumor and the presence or absence of spread to lymph nodes or to distant places of the body, determines the stage of lung cancer and, thereby, the chances of survival. The type of lung cancer (non small cell or small cell) and stage of disease, define the type of treatment needed

Over 80% of lung cancer cases arising from the use of snuff. But although the snuff is the leading cause and responsible for most cases, anyone can develop lung cancer.

Lung cancer is always treatable, regardless of size, location and extent of spread. It is believed that lung cancer develops over many years, now is time to grow when the symptoms begin to appear that will lead to a diagnosis.

The lungs contain many different cell types. Most of the lung are epithelial cells, a variety of cells that line the airways. The lungs also contain other types of cells such as nerve cells, producing hormones and structural or supporting cells.

Lung cancer begins when cells in the lung to lose control and begin to grow abnormally faster, accumulating and forming a mass or tumor (also be called lump, lesion or nodule). A cancerous tumor is, therefore, accumulation of large numbers of cancer cells, and appears as a nodule tissue anywhere in the lung.

Nearly all lung cancers are carcinomas, ie tumors that arise in lining tissues, in lung epithelial cells. In the case of lung cancer, tumors usually begin in the lining of the bronchi, but can also arise in other areas of the respiratory system such as the trachea, bronchioles, or alveoli. Over 95% of lung cancers belong to the group called bronchogenic carcinoma.
