Yeah. I’ve done both. Stopped over 20 years ago for cigars and 44 years ago with cigarettes. But you always inhale some cigar smoke and it adds up.
A friend got cancer of the throat from human papilloma virus. He smoked cigars for a few decades after quitting cigarettes. Lots of people have the virus and your body can fight it. He obviously had his mouth where it wasn’t supposed to be (think Michael Douglas). It took constant cigar smoke to weaken him enough for the cancer to take hold. He survived but it wasn’t lung cancer.
My cousin’s husband also had HPV-caused throat cancer, had surgery, rad/chemo and survives.
