causes of lung cancer
Most people would know the primary cause of lung cancer (after all there is so much propaganda about what increases the risk for lung cancer, the most). Yes, that smoking is the main culprit behind lung cancer (or behind the increased risk of lung cancer). Even passive smoking can slightly increase the risk of lung cancer. It is unfortunate that despite all the propaganda and know the people that smoking causes lung cancer, people continue to smoke. People working in industries that use a lot of asbestos and other chemicals / fumes, including a greater risk of lung cancer are involved.
While smoking is a major cause of lung cancer in smokers, passive smoking also causes lung cancer and heart disease in nonsmokers. There are about 20% of women with lung cancer who never smoked diagnosed (American Cancer Society). Some factors include not only the passive smoking: exposure to radon or asbestos, inhaling toxic chemicals or minerals, or simply genetically predisposed to get it. However, the head that Non smoking have generally positive response to the treatments for their cancer. Cancers are staged depending on how far it spreads. Staging of cancer is important for good at the most appropriate treatment method. A series of diagnostic tests such as CT, MRI, bronchoscopy, blood tests, bone scans and biopsies are used to determine how far the cancer has spread.Symptoms
One of the first symptoms of lung cancer is a nagging cough that’s not getting better. Often the cough gets worse with time and is associated with chronic pain in the chest. Hemoptysis is one of many early symptoms of lung cancer. In fact, coughing up blood is an important symptom of lung cancer patients to their physicians. Recurrent bronchitis or pneumonia sometimes indicates that the disease is present. Fatigue and shortness of breath are symptoms of, if you suspect that to observe the disease. No matter what are the symptoms below, if you lung cancer, they gradually progress in intensity of the disease.
These lung cancer symptoms do not always show that the disease is present. There are other, less dangerous conditions that can cause these symptoms. However, ignore the symptoms is dangerous, because if they point to lung cancer is the disease progress. Early treatment is the best way to successfully fight cancer, do not ignore these symptoms.The absence of symptoms does not necessarily reflect the early detection of disease to light, and the presence of nonspecific symptoms, the chest are often ignored. Both factors contribute to the fact that only about 15 percent of lung cancer patients in the early stages of the disease diagnosed. The later diagnosed with cancer, the less effective treatment options. Delays in the diagnosis of lung cancer patients, leading to a survival time of only 15 percent after five years of diagnosis.
