The number of people dying from the disease who have never smoked will overtake deaths from smoking-related lung cancer within a decade, research suggests.
It’s prompted the UK’s largest cancer surgery centre to issue a warning that there must be change in order to beat it.
Lung cancer is ranked as the deadliest type of cancer. Only one in 20 patients survive the cancer for more than ten years.
In the past, cancer researchers linked the illness to smoking, as nine out of ten deaths are caused by the disease.
But researchers are keen to expand public understanding of what else can cause the cancer – as smoking rates fall to an all time low.
Eric Lim, a consultant thoracic surgeon said that he had found a casual link between lung cancer in non-smokers.
He saw a jump in the number of patients that he treated who had never smoked.
The number of lung cancer patients that were non-smokers that he treated between 2008 and 2014 treated remained constant at 310 a year. However, the number who had never smoked jumped from 13 to 28 percent.
According to Cancer Research UK, there are at least 3,500 cases of lung cancer each year.
