Environment related problems harm both the planet and people’s life and health. Air pollution is bad for the ozone layer, but also for a series of medical conditions, such as lung problems or other respiratory issues. A new study found that lung cancer patients have reasons to worry about.
Recent research has brought to light that air pollution aggravates the health status of people suffering from lung cancer. There is a high probability that polluted air can reduce the lifespan of patients who had recently been diagnosed with lung cancer.
In the case of such a diagnose, there are 50 percent chances for the patient to live. The chances decrease by more almost a half (to 30 %) if the patient is exposed to unhealthy air.
An experiment was conducted by specialist Sandrah P. Eckel, who is an assistant professor at the University of Southern California (Los Angeles). The experiment was carried out with the help of 352,000 patients, and the results showed that toxins in the air we inhale tend to affect patients with lung cancer in its early stages. The study lasted for 21 years, from 1988 to 2009, and some of the patients reached terminal phase and died by the end of the study.
According to Immortal News, some of the statistics look as follows:
“The study found that people with early stage lung cancer survived for an average of 3.6 years, which fell to 2.4 years when they were exposed to high levels of particulate matter.”
Some researchers didn’t expect the outcome they have been left with. One of them is Doctor Jaime E. Hart (the Channing Division of Network Medicine), who didn’t expect such a severe effect of air pollution, as she stated the following:
“Before this study, there was very little evidence of the impact of air pollution on survival in individuals with lung cancer.”
She further added:
“The most interesting findings were that the impacts of pollution were very different by stage and histology at diagnosis, and the impact was strongest among those who traditionally have the highest survival rate.”
Even without the risks brought by air pollution, patients diagnosed with lung cancer still have little chance of living a long life. Usually, doctors predict at most five or six more years for them.
The study led by researcher Sandrah P. Eckel about the effects of air pollution on lung cancer patients was published in Thorax (journal).
