I read that some chemicals are considered cocarcinogens when combined with other substances.
Sloth B
Really? I didn’t know that. How does it work exactly?
Sloth A
Well, they don’t cause cancer on their own but can make other carcinogens much worse.

Root Explanation

Cocarcinogen → It is formed from "co-" (meaning together) and "carcinogen" (from Greek "karkinos", meaning crab, and "genes", meaning born of or produced by). The term refers to a substance that works together with another carcinogen to promote cancer development.

Memory Tip

Think of 'together' ('co-') working with a 'cancer-causing substance' ('carcinogen') — that's why cocarcinogen means a substance that acts together with another to cause cancer.
