My twin sister died in 2003 of lung-cancer. She was a heavy smoker. She told me she had quit smoking 5 years earlier, but that was obviously not long enough
My condolences...
I lost my Dad when i was 45. I never saw him smoke. He quit before I was born. Once the damage is done, it doesn’t just go away.
It’s not just being a smoker that will cause lung cancer. Lady from church died of lung cancer and she never smoked a day in her life.
Lost both of my parents to it though. All caught to late to treat. My Dad actually died of narcotic OD which stopped his heart, but Lung Cancer was the listed cause of death. Suspect same thing happened to my Mom as she survived longer than my dad did, the VA gave him 6 weeks, he was having chest x-rays every 3 months, and they failed to find it, he made 3 months, Mom was given 3 months and made 6 months.
What about all those coal minors breathing that dust way back before there were safety regs Grandpa had Black Lung from it. A bout of pneumonia actually was cause of death.
