[Malignancy in ACR 3 category mammographic lesions, masses and calcifications].
At screening mammography, lesions must be assigned to BI-RADS classification. Category 3 is used for nonpalpable probably benign lesions. This category is defined either by a subset of lesions that are so likely to be benign that follow-up is a reasonable alternative to immediate biopsy, or by a less than 2% malignancy rate for American BI-RADS, or than 5% for French ANAES. The initial work-up to analyze the lesion must be complete, not only with four screening standard views but with magnification views and sonography if necessary. The risk of malignancy is very low and the pronostic factors are the same as in screening detected carcinomas.
