Exploration d'un syndrome de masse clinique non inflammatoire du sein : recommandations pour la pratique clinique

Physical examination of a non-inflammatory palpable breast mass is not sufficient to eliminate a breast cancer (LE2). Mammography alone has a sensitivity between 70and 95% for the diagnosis of breast cancer (LE3). Echography alone has a sensitivity of 98 to 100% for the diagnosis of breast cancer (LE2). The core needle biopsy has a better sensitivity and specificity than the fine-needle aspiration for breast cancer diagnosis (LE2). The association of mammography and 2D echography presents excellent sensitivity and negative predictive value (close to 100 %) to exclude a breast cancer (LE3). A double evaluation using mammography and echography is recommended in the exploration of a non-inflammatory palpable breast mass (grade B).
