About Us

Founded in 2000, the International Society of Geriatric Oncology also known as SIOG (French acronym for Societé Internationale d’Oncologie Gériatrique) has been working to foster the development of health professionals in the field of geriatric oncology, for the optimisation of treatment of older adults with cancer. SIOG was registered as a non-profit organisation under the Swiss Law in 2012.

SIOG is a multidisciplinary team of oncology and geriatrics physicians, as well as allied health professionals and expert trainers with a unique collaborative approach to address the rising public health challenges related to ageing and cancer around the world. As of 2018, we count over 1700 members in more than 80 countries worldwide.

We are powered by global collaborations to strengthen the national capacity for Human Resources for Health (HRH) and to promote and advocate for SDG3 ‘Ensure healthy lives and promote wellbeing for all at all ages’.
