“The first Cancer Registry in Nigeria established in 1962, located within the Department of Pathology at the University College Hospital, Ibadan. Cancer incidence data from this registry were published for the time periods 1960- 1962, 1960- 1965, and 1960- 1969 in the first three volumes of Cancer Incidence in 5 Continents (CIV). IBCR became defunct in 2002, but was revived in 2009."
