Current trends in marking the tumor bed for radiation therapy after breast-conserving surgery for breast cancer

For local control after breast-conserving surgery for breast cancer, radiation therapy is an integral component of treatment. To reduce damage to the surrounding tissues, both modern modes of intensive modulated radiation therapy (IMRT) and volumetric modulated arc therapy (VMAT), as well as postoperative marking of the wound cavity with radiopaque clips or planning according to the visualized volume of postoperative seroma, are used. Existing methods for visualizing the volume of a postoperative wound are not sufficiently accurate, which dictates the need for their further improvement.
