A photocarcinogen is a substance which causes cancer when an organism is exposed to it, then illuminated. Many chemicals that are not carcinogenic can be photocarcinogenic when combined with exposure to light, especially UV. This can easily be understood from a photochemical perspective: The reactivity of a chemical substance itself might be low, but after illumination it transitions to an excited state, which is chemically much more reactive and therefore potentially … WebThe short answer is Yes, and not just because they are a chemical soup full of endocrine disruptors and carcinogens. That part, scary as it is, is actually the least of your worries.
