Delay in the diagnosis of breast cancer: the effect of the introduction of fine needle aspiration cytology to a breast clinic.
Fine needle aspiration cytology (FNAC) was introduced to a District General Hospital Breast Clinic in 1984 and since that time the rate of surgical excision biopsy for benign breast disease has halved. The rate of benign to malignant breast operations fell from 2.0 to 0.7 over a 7-year period from 1982 to 1988. During this period the diagnosis of breast cancer was made at the first clinic appointment in 85% of women. However, a delay in diagnosis of more than 50 days occurred in 33 patients (6.9%) and there was little difference in the annual rate of delayed diagnosis despite the addition of FNAC as an extra diagnostic tool in the later years of the study. Eighty-five per cent of patients with a delayed diagnosis were under the age of 55 (mean and median age 47) years. FNAC is a useful adjunct in the management of patients with diagnostic breast problems, but even in combination with mammography is not always sufficiently sensitive to exclude malignancy, particularly in young women.
