That's a new one on me. Smoking is a risk factor for many things, but being the cause of a PREVENTABLE cancer? i seriously doubt that.
And there are viruses that cause cancer. 98-99% of all cervical cancer is caused by the human pappiloma (sp?) virus - and HPV can be an STD.
My dentist's son got a brain tumor, he was going through chemo and radiation. He beat the cancer, thank God, but this happened about the time that the "scientists" were saying that giving your kids hot dogs that might be overly done might cause cancer due to nitrates.
Imagine my dentist weeping to me as told me how guilty she now felt for giving her kids hot dogs.
I was so made at the stupid "scientists" that use junk science just so that they can get grant money. They should see the harm they do to people, emotionally and mentally.
They say the same thing about bacon and almost everything that one eats, cooks, has in their home, their office, outdoors. Have a microwave? An old hairdryer? Wood Paneling? Carpet? Furniture? Drinking unfiltered water with nitrates in it? Drink regular coffee? Decaf? Use white coffee filters?
It's not just smoking.
Are you going to throw out everything in your life that "they" say causes cancer? No, you pick and choose. It's your right but don't force your choices on others.
Do you believe in global warming even though top climatologists have pooh poohed the concept? Most top scientists pooh pooh it but you rarely hear from them in the MSM.
The "intellectuals" are out of control..and for what? Money? Fame? God like stature? Because they are expected to publish so many studies a year to keep their jobs? Several have been caught and publically exposed for falsifying studies.
Sanity must return to the scientists, universities, and to this country.
