“*A carcinogen is a substance, organism or agent capable of causing cancer*”.
“*Cancer* is *a disease in which some of the body’s cells grow uncontrollably and spread to other parts of the body*”.
How does something like alcohol or tobacco cause cancer?
In: Biology
So every single time our cells divide their a tiny chance that they can turn into cancer cells. Thing’s that cause cancer are known to cause damage our DNA and that makes it more likely cells turn cancerous when they divide.
But also, when we say something “causes” cancer we means that something is linked to a noticeably increased risk in developing cancer. I know people have have smoked cigarettes their entire life and never developed cancer (lots of other health problems), but not cancer.Smoking is still basically the worst thing you could possible do to yourself that is, or was, widely practiced. Please don’t smoke.
