About the Society of Interventional Oncology (SIO)

The Society of Interventional Oncology (SIO) is a non-profit membership society 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 our clinical partners in medical, surgical, and radiation oncology. Our society offers a space for IO practitioners to continue their professional development, access and develop research opportunities, and advocate together for the advancement of this growing specialty.

SIO Vision Statement

SIO aims to make a meaningful difference in the lives of cancer patients by establishing interventional oncology as an essential pillar of cancer care worldwide.

SIO Mission Statement

SIO’s mission is to advance interventional oncology through research and evidence-based education that equip practitioners and multidisciplinary care teams to uphold clinical excellence, and through awareness that expands access and empowers patients to pursue life-changing treatment options.

We are here to advance SIO's mission to our patients and give information about what SIO is doing, so our patients have the option, the choice, of treatments. And these treatments can actually change their lives.
