A biopsy localization device made according to the invention includes a bioresorbable element, such as a cellulose. The bioresorbable element preferably carries a radiopaque marker. The bioresorbable element preferably swells to fill the biopsied open region. The bioresorbable element and radiopaque marker permit the biopsy site to be relocated by various techniques, including mammography and ultrasound. In addition, the bioresorbable element can be used as a therapeutic tool for treatment of the diseased lesion and for hemostasis.
