“…24 Inherent differences in the severity of abnormalities detected and the type of follow-up required may also affect timely followup. For example, the lower follow-up rates for colorectal cancer screening abnormalities may be due to the perceived inconvenience and invasive nature of the procedures involved.…”

“…Retrospective analyses of treatment delay raised the possibility that tumor proliferation may have been underestimated in the past, with an estimated loss of 5-year survival of 1.8 percentage points per month of delay over 1 to 6 months (34,35). Other reports were consistent with this finding, but an overview failed to detect a significant effect (36)(37)(38).…”

“…There is quite substantial evidence that among breast cancer cases patient delay of more than 3 months is associated with lower survival whereas no such association has been found for provider delay (Afzelius et al, 1994;Coates, 1999;Richards et al, 1999;Sainsbury et al, 1999).…”

Patient delay and stage of diagnosis among breast cancer patients in Germany – a population based study

et al. 2002

Early diagnosis is a tenet in oncology and should enable early treatment with the expectation of improved outcome. Extent and determinants of patient delay of diagnosis in breast cancer patients and its impact on stage of disease were examined in a population based study among female breast cancer patients in Germany. Two hundred and eighty-seven women, aged 18 to 80 years with newly diagnosed invasive symptomatic breast cancer, were interviewed with respect to the diagnostic process. Patient delay was defined as time from onset of first symptoms to first consultation of a doctor. Median patient delay was 16 days among symptomatic patients. Eighteen per cent of all breast cancer patients waited longer than 3 months before consulting a physician. Long patient delay was associated with old age, history of a benign mastopathy, obesity, and indices of health behaviour such as not knowing a gynaecologist for out-patient care and non-participation in general health screening examinations. A strong association between patient delay and stage at diagnosis was observed for poorly differentiated tumours. These results suggest that at risk groups for delaying consultation can be identified and that a substantial proportion of late stage diagnoses of poorly differentiated breast cancer cases could be avoided if all patients with breast cancer symptoms would present to a doctor within 1 month.
