FIELD: surgery and oncology.
SUBSTANCE: invention can be used for interstitial marking of breast tumors. The interstitial marker for tumor imaging includes a radiopaque element, which is designed for insertion with a localization needle. The radiopaque element is made of sterile non-reactive bovine bone meal, dyed blue, and is located in the lumen of the peripheral venous catheter. In particular cases of implementation or use, the interstitial marker can be placed in a plastic bag.
EFFECT: creation of an atraumatic, non-reactive, inexpensive and easy-to-manufacture biological marker for tumors imaging before and after neoadjuvant chemotherapy for radical breast resection.
