Surgery is the first step in the treatment of DCIS. Surgery may entail either a lumpectomy or a mastectomy. In a lumpectomy, only the abnormal tissue is removed, conserving the rest of the breast, while mastectomy involves removal of the entire breast.
If abnormal cells are found to have spread within the milk ducts, then a mastectomy may be recommended. Radiation therapy is often not performed following a mastectomy to treat DCIS.[3] For this reason, patients who wish or have a medical need to avoid radiation therapy may opt for mastectomy over lumpectomy. The choice of surgical procedures is individual for each patient and is best made collaboratively between the patient and her physician.[4]
Breast tumors may be either hormone-receptor positive, indicating that the cancer needs hormones to grow, or hormone-receptor negative, meaning it does not. The national Comprehensive Cancer Network recommends that women treated for hormone-receptor-positive DCIS with lumpectomy and radiation follow up with a five-year course of tamoxifen. This medication can lower the risk of DCIS recurrence as well as invasive breast cancer by preventing estrogen from binding to receptors. Because women who undergo mastectomy for DCIS have very low risk of recurrence, tamoxifen is not usually recommended in these cases.[5]
If you’ve recently been diagnosed with breast cancer, it can be difficult to digest all of the information you receive about your condition. At Iowa Radiology, we make sure to take the time to answer all of our patients’ questions so they have the information they need to make informed choices about their health care and to make them as comfortable as possible during procedures at our clinics.
