“*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
Your cells contain instructions for how to be a cell in your body. Things like tobacco cause those instructions to get scrambled, duplicated, or deleted. So you go from an instruction that says something like, “while you’re an embryo, grow a whole bunch, then chill” to “….grow a whole bunch…” And cells start multiplying when they’re not supposed to, invading into other parts of your body, and this is cancer.
