Lung Cancer Causes and symptoms

lung cancer is the most lethal in the United States. Among all causes of death, lung cancer ranks second after heart disease in men and third after heart disease and cerebrovascular disease in women. in 2002 alone, over 150,000 people in the United States died of lung cancer. Stay abreast of facts about lung cancer, the statistics of affliction are staggering and in most cases, lung cancer may even be avoided.

Causes of lung cancer

most people know the main cause of lung cancer (after all there is so much propaganda about what increases the risk of lung cancer the most). yes, smoking is the main cause of lung cancer (or behind the increased risk of lung cancer). Even passive smoking can slightly increase the risk of lung cancer. Itâ € ™ s unfortunate that even with all that propaganda and people knowing that smoking can cause lung cancer, people continue to smoke tobacco. People working in industries that involve extensive use of asbestos and other chemical substances / fumes are also at greater risk of lung cancer.

while smoking is the leading cause of lung cancer for smokers, secondhand smoke also causes lung cancer and coronary heart disease in nonsmokers. There are about 20% of women diagnosed with lung cancer who never smoked (American Cancer Society). some factors other than secondhand smoke include: exposure to radon or asbestos, inhalation of toxic chemicals or minerals, or simply be genetically predisposed to get it. however, the advantage is that non-smokers do generally respond positively to treatments for cancer.

Cancers

are organized according to how they spread. Staging of cancer is essential to choose the treatment option most appropriate. a number of diagnostic tests, such as scanners, MRI, endoscopy, blood tests, bone scans, and biopsies are used to how far the cancer has spread.

Signs and symptoms

The symptoms of lung cancer does not always indicate that the disease is present. There are other conditions that are much less dangerous than can cause these symptoms. however, ignoring the symptoms is dangerous, because if they are directed to lung cancer, the disease will continue to grow. Early treatment is the best way to effectively fight against lung cancer, we must not ignore these symptoms.

The absence of symptoms does not necessarily indicate early disease and the presence of non-specific chest symptoms can often unheeded. These two factors contribute to the fact that only 15 percent of patients with lung cancer are diagnosed at an early stage of the disease. Lung cancer is diagnosed later, treatment options are less effective. Delays in the diagnosis of lung cancer patients result in an overall survival of only 15 percent five years after diagnosis.
