Doctors can not always explain why one person develops lung cancer and others do not. However, studies have found the following risk factors for lung cancer:

Cigarettes

In most people, lung cancer is associated with risk factors for cigarettes. The incidence of lung cancer is closely related to smoking, with about 90% of lung cancers arising as a result of taking snuff. The more you smoke, the more likely you are to get lung cancer.

Passive smokers are at risk of lung cancer. Research has shown that passive smokers who live with smokers have a 24% increase in the risk of developing lung cancer compared with someone not living with a smoker.

Radon gas

The second most important risk factor for lung cancer is exposure to radon gas. Radon is a radioactive gas that you can not see, smell or taste. It forms in soil and rocks. People who work in mines may be exposed to radon. Radon damages lung cells and those exposed to radon are at increased risk of lung cancer. Radon causes lung cancer is even greater for smokers.

Asbestos fibers

Asbestos fibers are silicate fibers that can persist throughout life in lung tissue after exposure to asbestos. Exposure to asbestos, arsenic, chromium, nickel, soot, tar and other substances can cause lung cancer. People working in construction and chemical industries have a higher risk of lung cancer. The risk is higher for people with years of exposure. Read the rest of this entry »

It seems as lung cancer would be easy to catch and diagnose because its symptoms, but this is not always the case. Approximately 25% of people with any type of lung cancer has no symptoms and are unaware of their condition unless they are tested for anything else or until the cancer spreads. Then, cancer growth could be seen on radiographs, for example, and hopefully successful treatment could begin. The rest of the people who get lung cancer have some symptoms that should draw the attention of a physician immediately. Although lung cancer remains extremely difficult to treat and survival rates improve with early diagnosis.

The main symptoms of lung cancer include changes in existing cough, coughing up blood, a cough, or a chronic cough. Some people notice an increase in breathing difficulties, feel short of breath, wheezing or experience. Sometimes a hoarse voice, could be one of the symptoms of lung cancer if it occurs suddenly. Occasionally, people with lung cancer receiving continuous chest infections or recurrent pneumonia, because the lungs are damaged. If the cancer spreads to other body areas, there may be additional symptoms of lung cancer are not limited to the lungs. These may include pain, especially if lung cancer spreads to the bones. Alternatively, the lung cancer in the brain can cause changes in vision, or act as stroke damage and build muscle weakness on one side of the body.

From time to time if the metastatic lung cancer occurs in the brain also can create seizures. On the other hand, the cancer can spread to other parts of the body and many of the bodies may have no symptoms at all. There are a plethora of symptoms of lung cancer, but there are certainly a population that is most at risk for this cancer, including smokers and even former smokers Read the rest of this entry »

Can fruits and vegetables help prevent lung cancer?
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.

Mortality from lung cancer in Spanish women is increasing every year by 4%, although in men has stabilized and even begun to decline, according to Dr. Manuel has warned Domino Oncology Service, Fundación Jiménez Díaz Madrid, was quoted by Europa Press on the occasion of the European Week of Lung Cancer. While the incidence of lung cancer in women in Spain is the lowest in the world, from the 90′s, the incidence of this disease in women increases rapidly growing.

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.

Lung cancer is the most common form of cancer in Canada and one of the most deadly. Five years after diagnosis, only 14% of people with this disease are still alive. By comparison, 88% of women with breast cancer are alive five years after diagnosis.

Smoking is by far the leading cause of lung cancer, but cancer can also result from exposure to secondhand smoke tobacco or substances such as asbestos, radon gas and gasoline vapors .

Lung cancer takes two main forms: a small cell “(the most dangerous) and non-small cell. This last category is itself divided into three subgroups: adenocarcinoma, squamous cell carcinoma and large cell undifferentiated. There are other forms, but they are much rarer.

Smoking increases from 10 to 25 times the risk of being diagnosed with lung cancer. This is by far the main risk factor.

Other factors may also play a role, such as:

* Secondhand smoke;
* Exposure to carcinogens (asbestos, radon, gasoline fumes, etc.).
* Smoke wood stove;
* Frequent exposure to air pollution;
* Have a diet low in fruits and vegetables.

Preventing

* Do not smoke or quit.
* Avoid secondhand smoke.
* Adopt an anticancer diet (more fruits, vegetables, whole grains, less red meats and sausages; avoid excess calories).
* In an area where radon levels are high, to analyze the air in his house to check the radon level.

Lung cancer can be treated by various therapies that are often used in combination to provide optimal outcomes for patients. Surgical resection is the surgical process in which the tumor, and is usually recommended if the cancer has not metastasized (or spread) outside the lungs to other parts of the body.

There are several options for doing that may involve resection of minimally invasive surgery or full operation. The technique used will depend on many factors, especially the size and stage of cancer and tumors are accessible to a surgeon.

Thoracotomy performed by a surgeon makes an incision through the chest wall and the average sternotomy performed by entering the chest cavity through the sternum. The second method is usually used in surgery for lung cancer, but they simply involve the discomfort and prolonged patient stay in hospital with a recovery period longer.

# Tests magnetic resonance imaging (MRI) uses powerful magnets and radio waves to make modern computers detailed cross-sectional images. These images are similar to those produced with computed tomography, but are even more accurate in detecting spread of lung cancer to the brain or spinal cord.

# The positron emission tomography (PET): Using a sensitive tracer of low dose that accumulates in cancerous tissues. Bone scans require the injection of a small amount of radioactive substance into a vein. This substance accumulates in abnormal areas of bone that may arise from the spread of cancer.

# Sputum cytology: is examined under the microscope a sample of phlegm to see if it contains cancer cells. * Needle biopsy: A needle is inserted into the mass while the lungs are displayed on a computer tomograph. After removing a sample of the mass and is seen through a microscope for cancer cells.
