Hazard
Can something cause cancer under some circumstances?
IARC classifications answer this question by weighing evidence from studies in people, animals and biological mechanisms.
This explorer can help answer this
Use trusted World Health Organization IARC evidence to see which cancers have been linked to tobacco, infections, jobs, medicines, radiation, diet and the environment.
This one distinction changes how every result in the explorer should be read.
IARC classifications answer this question by weighing evidence from studies in people, animals and biological mechanisms.
That depends on how much, how often and how long someone was exposed—as well as age, genetics, other exposures and chance.
This tool cannot tell you what caused an individual's cancer, diagnose illness or show whether a medicine should be stopped. Most people with these exposures never develop cancer. For a personal concern, speak with a qualified health professional.
There is no wrong starting point. Search by a cancer, look up something you may encounter, or move through the full network.
