Human Cancer: Known Causes and Prevention by Organ Site

This poster presents the target organs for all agents classified as carcinogenic to humans (Group 1) by the IARC Monographs programme (in red text on the poster), and for the interventions showing sufficient evidence of a cancer-preventive effect in the IARC Handbooks of Cancer Prevention (in green text). The target organs are indicated on a schematic “virtual human”, who has both male and female organs.

The poster is updated after each meeting of the IARC Monographs or IARC Handbooks Working Group at which a new Group 1 agent or cancer-preventive effect is identified, or a new target organ for a known agent or effect is established.
