It’s all genetics.
My grandfather smoked two packs of unfiltered Camels for 70 years and didn’t die of cancer never even had cancer.
He died at the age of 84.
-Block!
The statement you made is a common one and there is truth in it.
Would you recommend people smoke based on your grandfather's experience?
What did your grandfather die of?
Genetics or perhaps what is more likely, the strength of your immune system (and you can call that genetics if you like) has a lot to do with your body's ability to neutralize cancer. Some people who have less resistance to cancer will get it by smoking.
Everybody gets cancer cells from time to time in their body but some people's immune systems neutralize them. Some don't. The reason most cancers occur in older people is that the immune system weakens with age.
Good genetics often does not pass through to all descendants equally. Your brother, like your grandfather may not get cancer from smoking but you might.
I suggest you smoke 2-3 packs a day for 50 years to test this theory.
In addition to the toxic chemical pollutants in cigarette smoke there is also radiation which can cause cancer.
There are survivors of the Hiroshima atomic bomb who did not die of cancer but many did.
Would you advise close proximity to atomic bomb blasts based on that?
