Question

Will it cause us cancer if we eat rust?​

Answer 1

Answer:

As long as the tongs are clean a bit of rust will not harm you. Rust is really iron oxide, a rather benign substance in small quantities. You usually shouldn't eat a pound of it though.

Answer 2

Tobacco

It doesn't matter whether you're a smoker or breathing in someone else's smoke. At least 70 chemicals in tobacco are known to cause cancer by damaging your DNA.

Smokeless tobacco may seem safer, but it can lead to cancer, too. Even light smoking raises your risk, so talk to your doctor about ways to quit
