Previous studies reported increases in the proportion of patients in the US and UK with lung cancer who never smoked cigarettes,1,2 but these were based on small sample sizes from hospital data rather than population-based cancer registries. Beginning in 2011, the US Centers for Disease Control and Prevention (CDC) National Program of Cancer Registries supported a comparative effectiveness research project to abstract cigarette smoking history from the medical records of patients.3 Using these population-based data, we examined cigarette smoking patterns by demographic and clinical characteristics among patients with lung cancer.

    Non-Smoking Women & Men Getting Lung Cancer - use of household, hygiene, grooming and other consumer products are to blame also
    Jeffery Howard, Cosmology, esthetician | Ginger Howard (wife)Cosmetologist/Manager
    The use of products daily for hygiene including, toothpaste, deodorant, antiperspirant, hair products, dry hair sprays, and cosmetic sprays and fumes are to blame. Big sprays, tanning sprays, sunblocks, par fumes and body sprays. Air freshness, room sprays, cleaning products, fumes from household disinfectant products. Car sprays, car cleaners and other truck/RV cleaning products.
    Foods we eat like ketchup containing chlorine for example and our water filtration system using chemicals to purify and the distilled water chemical process. Plastic containers that our food is sold in. Teflon our food is baked and fried on. All of these add up
    over daily use by men and women who are “non” smokers and contribute to the development of foreign free radicals our body inhales and ingest. Over year's and years of this build-up, our body can not fight against these free radicals AND the other colds and flu and disease we are exposed to. Resulting in a reproduction of abnormal “cancerous” cells. This is why you're seeing a spike in cancer for lung cancer for none smokers and other cancers in young people today.

    Story of Cigarettes smoking only?
    Jeffrey Sterr |
    Does this study only address cigarette smoking or does it include smoking of all kinds?
    CONFLICT OF INTEREST: None Reported
    Looking at statistics...
    Laszlo Meszaros, Ph.D. | University of Kaposvar, Hungary
    It is worth taking a look at statistics of smoking vs. lung cancer incidents per country... Only very weak (if any) correlation one would find.
