The Dangerous of Residual Cigarette Smokes
The risk of exposure to snuff does not end when you turn off the cigarette. It is well known the danger faced by passive smokers inhaling the smoke that surrounds them: no safe level of exposure. But what happens when white cloud that disappears? Not only is a bad smell in hair or clothes.
The residual cigarette smoke can also cause cancer. A new study, published in ‘Proceedings of the National Academy of Sciences’ ( ‘PNAS’), warning of what he calls “third-hand smoke”, ie, “residual [...] that nicotine has been absorbed by certain areas. It seems that it reacts with nitrous acid present in the environment and, as a result of this, form a kind of nitrosamines which are carcinogens.

Why should I quit?
Everyone knows that smoking can cause cancer when you get older, but did you know that also has negative effects on your body right now? A cigarette contains about 4000 chemicals, and at least 43 of the chemicals cause cancer in humans. Some of the other chemicals found in poisons. Some of the worst are:

Factors of Lung Cancer
This cancer is one that takes more lives annually and affects people 40 and older. Since 85% of those who suffer are smokers, snuff is the major risk factor for developing it. Only one of every eight people who suffer are not smokers.
There are also other substances such as asbestos, uranium or radon is a colorless, odorless gas that builds up in homes and comes from the stoves, which are also risk factors for lung cancer.
Other risk factors include industrial pollution, smoke from factories or cars or hormonal factors of the person that make it more susceptible to developing it. A risk factor can also be the presence of scars in the lung, caused by surgery, bullets or knives.
Kinds of Lung Cancer Diagnostics
# 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.

How to Diagnostics Lung Cancer?
Because lung cancer symptoms often do not manifest until the disease is advanced, only 15 percent of cases are detected in its early stages. Many lung cancer cases are diagnosed in early stage by accident, which means that are detected as a result of medical tests carried out due to other unrelated health problem.
A lung biopsy was used to confirm or refute a possible diagnosis of cancer as well as provide valuable information to determine the appropriate treatment. If it is eventually detected lung cancer, additional tests are carried out to determine how far the disease has spread, including:

How to Remove Pleural Tumors
Overall, pleural tumors can not be removed surgically. It must treat the original cancer (primary). Depending on the type of primary cancer, radiotherapy or chemotherapy may be appropriate.
Therapeutic thoracentesis may be performed if fluid accumulation is large and causing pressure, shortness of breath or other breathing problems (such as low oxygen levels). Removing the fluid may allow the lung to expand more and can ease breathing difficulties.
To prevent fluid from building up again, sometimes medication will be placed in the thoracic space through a tube or a surgeon can insert a scope through a small incision in the chest wall to remove fluid (thoracoscopy). Then a drug is sprayed or powder on the surface to prevent lung cancer cells produce more fluid in the future.

Common Treatments of Lung Cancer
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.
Common Symptoms of Lung Cancer
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.
Diagnosis and Treatments of Lung Cancer
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.
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.
