[Breast cancer during pregnancy].

Approximately 2-3% of all breast cancers coincide with pregnancy or lactation and this tumour affects one to four out of 10000 pregnant women. Breast cancer associated with pregnancy (BCAP) has generally been believed to have a particularly grim prognosis. Several recent studies suggest however, that survival in BCAP does not substantially differ from that of non-pregnant, age and stage matched patients. BCAP may managed with standard methods. Surgery should be considered in all patients deemed to be operable. Therapeutic abortion does not need to be routinely performed, unless adjuvant chemotherapy or radiotherapy is to be applied or the patient necessitates systemic therapy for advanced disease. Prophylactic ovarian ablation does not influence significantly the course of BCAP and should be undertaken only in case of progressive or recurrent disease.
