Breast screening: interval cancer data, April 2003 to March 2005
NHSBSP occasional report 1203: national collation of interval cancer data.
The aim of breast screening services is to decrease incidence of, and mortality from, breast cancer.
A proportion of cancers are diagnosed between scheduled screening episodes.
These cancers are called ‘interval cancers’, and are defined as ‘cancers diagnosed following a normal screening result during the interval beginning with the closure of the previous NHS screening episode and ending when the next screening episode is due to commence’.
