Concerns About Breast Pain: How Useful Is Imaging?

Abstract

Background: Breast pain is one of the most common reasons for referral to breast imaging. Objectives: This study aimed to determine the diagnostic yield of mammography and sonomammography in women complaining of breast pain in a teaching hospital in Southeast Nigeria. Methods: This descriptive study analyzed the mammographic/sonomammographic images and records of 241 consecutive adult women aged 18 - 81 years with breast pain who presented to the radiology department over three years. A non-random sampling method was employed to select the participants. The extracted variables were patient’s age, positive clinical history of breast pain, laterality of breast pain, type of imaging, presence or absence of lesion, type, and laterality of lesions if present, and Breast Imaging Reporting and Data System (BI-RADS) assignment of imaging findings on mammography and sonomammography. The descriptive analysis of continuous variables and inferential statistics of ordinal data were performed with Microsoft Excel and chi-squared test, respectively. In this study, P < 0.05 was set as the significance level. Results: Most women (20%) with a complaint of breast pain were in the 40 - 44-year age group. Moreover, 32.3%, 33.2%, and 34.4% of the participants had left-sided, right-sided, and bilateral breast pain, respectively. Among the participants, 118 and 123 women had mammography and sonomammography, respectively. Furthermore, 76.3% had normal findings on mammography or sonomammography, and only 23.7% had positive imaging findings on breast imaging. These lesions were mostly observed among the women in the age group of 45 - 49 years. Of those with lesions detected on imaging, 79.2% and 20.8% demonstrated benign and malignant attributes, respectively. Masses with definite benign attributes assigned BI-RADS II were mostly fibroadenomata and cysts. Inferential statistics indicated that unilateral mastalgia was more likely to be associated with a breast lesion, while bilateral mastalgia usually resulted in normal breast imaging findings. Conclusions: Women referring to the Radiology Department with a complaint of breast pain alone are unlikely to have any significant breast imaging finding; hence, imaging serves as a tool for assuaging the anxiety of these patients and reassuring the referring physician. Unilateral but not bilateral mastalgia is likely to yield positive imaging findings, which are largely benign.
