Agreed. A friend who has never smoked or drank alcohol in his life has been hit with throat cancer, lung cancer & prostate cancer. He was cleared about 6 months ago and the lung cancer is back.
It's tough to watch, he has to know he has a bulls eye on his back.
I had a $6000 genetics test for BRCA that included tests for known lung cancer gene issues. It was free due to family history of Ovarian cancer.
It really means nothing but if you have the genetic quirk at least you have something to wave at a DR to get you tested if you have symptoms that could be lung cancer.
