What is Lung Cancer?

Saturday, July 17th, 2010

What is Lung 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 Stage of Lung Cancer

Wednesday, July 14th, 2010

The Stage of Lung Cancer
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 Difference Between Mesothelioma and Lung Cancer

Saturday, July 10th, 2010

The Difference Between Mesothelioma and Lung Cancer
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 Dangerous of A Lung transplant

Saturday, July 3rd, 2010

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.

The Dangerous of A Lung transplant

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.

Preventing Lung Cancer

Monday, May 31st, 2010

preveting lung cancerThe 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.

Lung Cancer and vegetables passive smoking

lun cancer and vegetables passive smokingWhat if you never smoked? eat as directed. ‘can also save from lung cancer in non smokers.

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.

Lung cancer chemotherapy

Wednesday, May 12th, 2010

lung cancer chemotherapy canbe treated withoutLung cancer occurs when there is an unusual growth of cells in the lung tissue growth, usually malignant, metastasis and proliferation may lead to other body tissues. This type of cancer is divided by the size and appearance of cells: small cell lung cancer and small cell.

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.

Lung Cancer: the Deadliest of all

Wednesday, April 21st, 2010

According to statistics involving all the world, lung cancer is the most kills: even more than breast, prostate, colon, skin and all the others together.

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.

Lung Cancer: What and how (II)

Tuesday, March 23rd, 2010

Lung Cancer

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.

Lung Cancer: What and how (I)

Monday, March 22nd, 2010

Benign and malignant tumors are named for the spot of the tumor originates. Thus, lung cancer begins to develop in the lungs. Some malignant tumors originate elsewhere in the body and spread to the lungs. Are lung metastases. But in this case are not lung cancer itself: keep the name of their place of origin. For example, breast cancer may give lung metastases, but still called breast cancer.

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.
