Didn't they live in Los Angeles for a time? The air there *has* to be significantly carcinogenic....
Hey, now. L.A. is the shiny beacon of liberalism on the hill. That's blasphemy, Spktyr. Blasphemy I say.

Sorta didn't matter where they lived. Lung cancer is the greatest cancer killer worldwide.
I would like to know where she lived throughout her life. Certain areas of the Country have heavy concentrations of radon gas. Radon can seep into the living or working environment and become entrapped. Radon testing and eradication only became SOP about 15 years ago. Radon gas exposure has a very high correlation with lung cancer. So, maybe second hand smoke was the cause or a factor in combination with other factors, or maybe second hand smoke has nothing to do with anything.
