Breast Cancer Screening Frequency and Overdiagnosis
In their interesting article, Arleo et al [1] observe that in a series of 479 untreated breast cancers (1.4% of screening-detected cases reported by 42 experienced imaging specialists), none spontaneously disappeared or regressed. On the basis of this finding, they argue that there is no point in delaying the initiation of screening un til after 40 years of age or in providing less frequent (biennial) tests because potentially overdiagnosed cases left undetected (and consequently untreated) by a less-than-intensive screening protocol would still be detected later when the time of screening eventually comes.
