A bit of background (from an unlikely source). The Tl;DR: \* Group 1: carcinogenic (this includes cigarettes, the HPV viruses that cause cervical cancer, and ionizing radiation) \* Group 2A: probably carcinogenic (this includes red meat, hot beverages, and working as a hairdresser) \* Group 2B: possibly carcinogenic (this is the group aspartame reportedly may end up in) \* Group 3: not classifiable \* Group 4: probably not carcinogenic (this list contains zero items; a chemical called caprolactam was previously on it, but was moved to group 3) These are not designations of cancer *risk*, but of *the chance that there is a detectable link of some kind*. https://lifehacker.com/aspartames-possible-carcinogen-designation-means-basica-1850590970 https://lifehacker.com/aspartames-possible-carcinogen-design...
