Lung cancer .. Smoking is not the only defendant!

Lung cancer .. Smoking is not the only defendant!

Lung cancer .. General Idea:
lung cancer is the leading cause of death among men and women alike. But this has not always been the base, it was not lung cancer that spread before the prevalence of smoking in its current form. Smoking causes 90 percent of lung cancer cases, while causing gases and pollutants such as radon and chemical contaminants small percentage of cases these days. And provide some of the newly developed medicines new hope to those who have been diagnosed with this type of cancer.

Cancer and respiratory symptoms:
Lung cancer begins gradually, without any symptoms or warning signs prior With the development of the disease begin Some symptoms begin non-distinctive to emerge, which include:
• chronic cough and persistent.
• severe pain in the chest, especially when breathing deeply.
• whistling sound from the patient's chest and shortness of breath.
• cough accompanied by bloody sputum.
• fatigue and fatigue.

Types of lung cancer:
Two main types of lung cancers are differentiating between them depending on the form of the cancer cells under a microscope.
- Small cell cancer is known as b (SCLC) the most dangerous types where he could spread to all parts of the body in its early stages, which is strongly linked with cigarettes where rare presence in non-smokers.
- The second type is known as non-small cell cancer (NSCLC), which is characterized by slower growth and represents the majority of infected cases of lung cancer, where the rate of about 90% of the total with lung cancer.

Survival rates of lung cancer:
Most of the available statistics on lung cancer may be a bit misleading. Statistical which relies recent American Cancer Society on cases that were diagnosed between 1988 and 2000.
According to the progression of the disease and stage; ranges proportion of life for five years after the diagnosis of (1%) and up to (49%) of patients with lung cancer from second type (NSCLC). But the case for change a little better for patients who have been newly diagnosed as a result of the development of treatment methods over the past decade.

Treatment of lung cancer in its early stages :
when lung cancer is detected from the first type known as small cell carcinoma (SCLC) before the start of spread outside the borders of the lung ,
so very feasible surgical treatment  . The surgeon can remove the affected part of the lung or pneumonectomy entire infected when necessary,
chemotherapy or radiation therapy after surgery to kill any remaining cancer cells . At other times . the surgery is not feasible where the disease has already spread to the time of diagnosis .

Treatment of late lung cancer :
When the tumor is in the advanced stages and is treatable , it is recommended for the patient with drugs to raise the quality of life and increase the period to keep it alive, can chemotherapy and radiation to reduce the size of the tumor in order to assist in controlling the symptoms resulting from it , such as bone pain or airway obstruction . It is also( chemotherapy) is the main treatment for lung cancer patients from the first type known as small cell carcinoma (SCLC).

Lung cancer and its relationship with radon gas :
Radon is a natural radioactive gas which exists in large quantities in specific areas of the United States of America , and this gas is possible is formed inside the houses which increases the risk of lung cancer , especially among smokers . This element is considered the second most elements that cause cancer of the lungs where it is associated more than 12 % of the lung cancer mortality. One of the main disadvantages of this gas that no odor or color , but can indistinguishable some simple tests .

Air pollution and its relationship to lung cancer :
It is possible that air pollution contributes to increase the incidence of lung cancer despite the low rate of smoking . Experts assert that the air pollution comes from cars , factories , power plants contribute in one way or another to increase the incidence of lung cancer the same effect of passive smoking . Air pollution causes 50 percent of lung cancer deaths at the global level .

Causative risk factors for lung cancer :
- family history of cases similar to lung cancer .
- Drinking contaminated water at high rates of arsenic.

Protective factors of lung cancer:
Respiratory cancer is one of the most deadly types of cancer to humans, but it remains the most fortunate in terms of prevention opportunities. Where summed up in inter-specific: stay away from smoking. Where the death Fall from lung cancer TO 50 % within five years of quitting smoking for those who smoked a pack a day,
