Radio-pathological correlation of occult tumor of the breast.
Small tumors of the breast, both benign and malignant, may remain clinically silent for some time before they become large enough to be palpable. In many cases the tumor is revealed on a mammogram that is performed only as part of a routine check-up. The spectrum of radiographic appearances of these "occult" tumors is described and correlated with histological findings. In a significant number of cases there is an overlap in mammographic appearance of these nonpalpable benign and malignant lesions and a biopsy is necessary. The techniques of spot localization are discussed, and the importance of this procedure prior to biopsy is stressed as an aid to the surgeon in localizing the abnormality. Results of studies and attempting to analyze and classify high risk radiographic patterns are reviewed. Reduction in mortality lies in detection of breast cancer in as early a stage as possible.
