The Catalan Institute of Oncology (ICO) is a public centre working exclusively in the field of cancer. Its approach to the disease is comprehensive, combining, all in one organisation, prevention, care, specialised training and research.

The ICO is a public company created in 1995 by the Ministry of Health of the Government of Catalonia. It went into service a year later, operating from the Hospital Duran i Reynals in L'Hospitalet de Llobregat. Seven years later, in 2002, ICO Girona opened its doors, located in Hospital Universitari Doctor Josep Trueta, followed by ICO Badalona a year later, at the Hospital Universitari Germans Trias i Pujol. In 2014 ICO Camp de Tarragona and Terres de l'Ebre, in Hospital Universitari Joan XXIII and in Verge de la Cinta was launched. Currently, ICO is an oncology referral centre for more than 40% of the adult population of Catalonia.
