Mammography screening in general practice - a pilot study

Abstract

Objectives: To evaluate the acceptability, feasibility and performance of a mammography screening programme for female patients in general practice. Design: A cross sectional study. Setting: A general practice clinic and a resiona/ hospital in Hong Kong. Subjects: 500 Chinese women aged 45 years or older attending a university teaching general practice clinic on Hong Kong Island. Main outcome measures: The rates of uptake of screening, retakes, recall for further evaluation and fine needle aspiration (FNA), and participants' opinion on mammography. Results: The uptake rate of screening was 37%. Mammography was feasible for all participants, 12% had additional films and 7% required retakes. Sixteen percent were recalled for further evaluation, 4% had FNA, one had an excisional biopsy which revealed no cancer. Most women rated pain of mammography mild to moderate and did not find it embarrassing, 98% said that they would recommend it to their friends and 87% indicated that they would do it again. Conclusions: Mammography screening for Chinese women presenting to general practice was technically feasible. Most women found the experience of mammography screening acceptable. The uptake rate of mammography screening was much lower than what would be required to benefit the overall breast cancer mortality. There was also room for improvement in our retake and recall rates. We need to weigh the possible benefit of mammography screening against the stress and resources associated with additional films, retakes, recalls for further evaluation, FNA and excisional biopsy in individuals with false positive results.
