Causes, symptoms, treatment and prognosis for stage IV lung cancer

What causes lung cancer and why?
The most common cause of lung cancer (small cell [SCLC] and non-small cell [NSCLC]) is smoking (the SCLC and NSCLC)-including passive (second-hand) smoke. However, other causes may be:
Inhaling harmful vapours (gases such as radon).Occupational health and safety (asbestos factories, carpet mills, Fireworks industries, etc.).
The main reason for the outbreak of lung cancer due to the fact that the lungs are one of the bodies that are most exposed to the external environment, more than all other organs in the body.
What are the symptoms of stage IV lung cancer?
Early lung cancer symptoms are not usually apparent for most patients; But, as they become apparent-later symptoms may include the following:
Pain in the arms, back, hips and shoulders (shows metastases [spread] of the disease).Persistent cough ([smoker's cough] often blood can be coughed up-known as hemoptysis or haemoptysis).Problems swallowing caused by an invasion of the esophagus (hoarseness of the throat).Recurrent pneumonia or bronchitis.Seizures and weakness in the body [weakness is often due to weight loss).Shortness of breath and wheezing (often with a slight burning sensation can be felt in the trachea [windpipe] and chest area.Visionary problems and headaches (mild-pounding) with indication of an invasion of the brain (brain tumor).Yellowing of the skin caused by a liver violation (jaundice).
What treatment is available for stage IV lung cancer?
Due to lung cancer is usually not diagnosed until a late settings is usually limited to trying to prevent multiple metastases, and try to give a patient an extended forecast (lifetime).
Chemotherapy (to prolong a patient's prognosis), however, is usually the treatment of choice-as surgical treatments is of negligible due to the metastasis of the cancer already has affected too many organs in the body (impossible to remove as much of the body and for a patient to survive afterwards).
Other palliative treatments (additional) may also be considered, such as: radiation therapies and clinical trials treatments [usually a combination of new treatments and drugs]).
What is the prognosis for stage IV lung cancer?
Prognosis for stage IV lung cancer is unfortunately bad to say mildly (due to late discovery). In most cases, there are estimated to be only a 10% 5-year survival rate for NSCLC and with a median survival [when 50% of the patients are still alive, and 50% has gone away] of only about 8 months. This will be further reduced to about a 5% 5-year survival rate with the SCLC, and only a few months when it is not treated.
Although influential factors may include: age, health, choice of treatment and the patient's response to treatment, and the specific characteristics of the tumor. Also it has been known for some cancer patients have survived against all odds longer than others (due in main to the body will be more accommodating to the treatments).
