About 50% of the supply is concentrated in Bogota, Antioquia and Valle del Cauca. The departments of Putumayo and Amazonas group, with the exception of Vaupés did not recorded cancer services. 87.8% oncology health services were offered by health institutions and 12.2% were provided by independent professionals. 66.7% of oncology health services were clinical consult services, 17.4% were related to support for diagnosis and therapeutic supplementation and 15.9% related to surgical services. 87.9% of the supply of oncological services in Colombia is in the private sector.Conclusions: The relationship between the groups of services is asymmetric, with few providers that jointly supply the basic services of oncological treatment, which reflects the fragmentation in the provision.
