The Cancer Registries (RT) are structures responsible for the collection and registration of all tumors occurring in a given territory. The primary role of a Cancer Registry is to establish and manage over time an archive of all new cancer cases diagnosed and to ensure that the data is recorded rigorously and continuously and systematically.
Most of the Italian registers are population registers, that is, they collect data relating to cancer diseases of all the residents of a given territory (it can be a single city or an entire region, a province or the territory of an ASL).
Alongside the general population registers, there are specialized registers, which collect information on a single type of tumor or on specific age groups or on occupational cancers.
