About SIO

The Society of Interventional Oncology (SIO) is a non-profit association that supports and promotes the field of interventional oncology (IO).

SIO provides a community for IO professionals to connect and work together to advance IO as the fourth pillar of cancer therapy worldwide alongside medical, surgical and radiation oncology. SIO offers a space for IO practitioners to continue their professional development, access advocacy and research, and engage in idea-sharing with peers.

SIO was established in January of 2017 by the Board of Directors of the former conference WCIO, now known as SIO's Annual Scientific Meeting.
