eli5: Why does it seem like everything is carcinogenic and does that mean if it is, it causes cancer?

846 views

I feel like I am always hearing about how things are carcinogenic, like red meat or air conditioners or aspartame. Why does it seem like *so* many things are carcinogenic and does that mean they cause cancer? Because it’s starting to feel like everything causes cancer…

This is the type of thing that gets my anxiety going so I’d love if someone who understands this better than I do can explain it.

That’s easy. Everything *does* cause cancer.

OK, that isn’t strictly true. However, the number of things that increase your risk of certain cancers is enormous. While minimizing your risk of cancer is a good idea, avoiding anything close to all carcinogens just isn’t going to happen.

Carcinogens *can* cause cancer. This doesn’t mean that they will, just that they can. And while there are things it is worthwhile to avoid, you just kind of have to accept that you will encounter them in your day-to-day life.
