What is the percentage of lung cancer patients that are smokers?

lung cancer



I would like to know the ratio of smoker vs non smoker in people diagnosed with lung cancer. Please provide a link.
I’m not looking for “caused by smoking” , those stats can be spun. I’m looking for smokers vs non smokers strictly. What percentage?

    According to the National Institutes Of Health, “Thun noted that 85 percent to 90 percent of lung cancer cases are caused by smoking, which translates into roughly 1.4 million lung cancer deaths across the globe each year.”

    The articles are cited below with related information.

    Here’s a Canadian study you should find interesting.

    Male smokers – lifetime risk of lung cancer is 1 in 6

    Female smokers – the risk of lung cancer is 1 in 9

    Risk of lung cancer in non-smokers is 1 in 77
