Validity of breast cancer registration from one hospital into the Swedish National Cancer Registry 1961-1970.

The validity of the Swedish Cancer Registry data on invasive female breast cancer in Malmö 1961-1970 was investigated. A total of 1311 entries in the register were examined, each entry representing an individual tumour, and compared to data from medical records and local registries. In 137 cases (10.5%) registered in the Swedish Cancer Registry, divergencies were found, of which at least 121 were overregistrations (9.2%). Forty-three tumours were identified meriting inclusion but not registered, giving an underregistration of 3.5%. The age distribution among the excluded cases differed somewhat from that of the verified cases.
