Breast Imaging Following Breast Conservation Therapy
For many women with newly diagnosed breast cancer, breast conservation is a safe, effective alternative to mastectomy. Breast conservation surgery involves removal of the tumor with a margin of normal breast tissue. In a few patients with very limited disease, the surgical excision alone is adequate local therapy. In the vast majority of patients, surgery is followed by breast radiotherapy (the combination is known as breast conservation therapy [BCT]). Radiotherapy is very effective in suppressing in-breast tumor recurrence and is most commonly delivered using conventional whole breast radiotherapy (WB-XRT). Accelerated, partial breast irradiation (APBI) is an alternative form of postsurgical radiotherapy that is currently being studied in clinical trials, and therefore, may be seen with increasing frequency in clinical practice. The overarching goal of breast conservation is to remove the tumor while minimizing chances for an ipsilateral breast tumor recurrence (IBTR). This chapter focuses on breast imaging after breast conservation therapy and reviews normal, expected findings in contrast to those suggestive of malignancy.
