Screening for breast cancer in Ghent, Belgium: first results of a programme involving the existing health services.

ABSTRACT

In 1992, a population-based breast cancer screening programme was initiated in the municipality of Ghent all women aged 40-69 years were personally invited to attend a local radiology unit for a mammogram, after being examined by a general practitioner or gynaecologist of their choice. The results of history taking, clinical breast examination, first and second reading, further investigation and primary treatment were registered. In total, 24.3% of the eligible population was screened in the period 1992-1994. The recall and biopsy rates were 2.9% and 1.4%, respectively. The cancer detection rate was 8.1 per 1000 women screened. Of all cancers detected, 88.0% (66/75) were invasive. Of these, 35.9% (23/64) measured 10 mm or less in diameter. The benign to malignant biopsy ratio was 0.7. Apart from the low participation, these results suggest that the programme is effective, compared with reference standards and the results of other studies.
