General information about biopsies
In recent years there has been a rapid development in the invasive diagnostic approach to breast lesions. All modern and fully equipped breast centers are internationally accepted to investigate with percutaneous biopsy all lesions that are suspected of malignancy (BI-RADS 4 and 5) and to plan open surgical biopsy only where it is not technically possible to perform percutaneous biopsy. The radiologist can choose the type of biopsy he will use from many different ones. In order to decide the appropriate type of biopsy, the following parameters should be considered: the size of the lesion, whether the lesion is palpable or non-palpable, its anatomical location, whether it is shown on the mammogram or ultrasound or only one of the two examinations, the morphology of the lesion, for example if it concerns solid lesion or microcalcifications and the size of the breasts.
