title: Indications for breast conservation in early stage breast cancer.
abstract: Breast conservation, utilizing limited excisional breast surgery and axillary lymphadenectomy followed by radiation therapy can achieve excellent local/regional control and survival in many breast cancer patients. With average sized tumors, where larger volume resections are performed the results can equal that of the modified radical mastectomy. However, smaller tumors do very well with breast removal so it is a challenge to demonstrate that the long-term results of breast conservation in earlier stage disease are equivalent to mastectomy. Small or occult tumors do not always indicate localized disease and suitability for breast conservation depends on a combination of factors: tumor size and ratio of tumor to breast volume, cell type, location of tumor, obtaining clear margins, the mammographic picture, multicentricity, and the probability of axillary lymph node involvement. It is important to select patients for conservation where an equivalent survival can be expected. Recurrence in the radiated breast usually is diagnosed and treated at a more advanced stage than the disease which was initially treated conservatively. It is difficult to manage and carries a poorer prognosis.
