It is a sad reality of our ear that irrespective of immense development in the field of science, cancer is an incurable disease. Most of their victims are cured in early stages. One of the worst cancer diseases is a lung cancer. Lung is a very vital organ of human body; all organs of the body totally rely upon the oxygenated blood which is purified in lungs. This is the dilemma that most of those patients who are discovered suffering from this case; their disease is diagnosed in later third or fourth stage where life expectancy is very low, maximum one year. At 4 stage of lung cancer almost every vital organ of the body is attacked by cancer cells. Through blood cancer cells are transported to every vital organ of the body. . In addition to variations between different people, it is important to keep in mind that statistics are frequently a few years old. For example, the most recent statistics we have for lung cancer are from 2005. With advances in treatment, statistics may not be the same as they were when newer treatments were unavailable.
It is found that the median stage 4 non-small cell lung cancer life expectancy (the time at which 50% of patients are alive and 50% have passed away) is only around 8 months. The 5-year survival rate that is the percent of people who are expected to be alive 5 years after a diagnosis of stage 4 lung cancer is sadly less than 10%. As in 4 stage lung cancer life expectancy is very rare and low, people must have awareness to this disease. They must know the causing factors of this disease and then restrain themselves from those causes. Lung cancer is also called the silent killer as its symptoms tend to appear in 4 stage where it becomes impossible for medical science to cure.
One last thing which is very important to keep in mind, irrespective of the fact that in stage 4 lung cancer is not usually curable, it is treatable. These treatments may not only improve survival, but help the victim in reliving his discomfort and pain. Latest and modern ways of diagnosis in the field of science has enabled doctors to scrutinize the condition of patients, for example through MRI doctors are able to see the effected organs and the damaged parts, and thus in near future through these in formations they will be able to discover the remedy of this disease or at least a way out to diagnose it in early stages. Several treatments are currently being evaluated in clinical trials and offer hope that stage 4 lung cancer life expectancy will improve in the future.
