Pregnancy-associated breast cancer

Pregnancy-associated breast cancer is one of the leading pregnancy-related types of cancer with an increasing incidence. It represents a special situation which requires careful attention for the medical team in fulfilling the goals of the treatment: the cure of the disease and the well-being of the pregnancy. The decisions regarding the most appropriate therapeutic methods should be made by a multidisciplinary team after offering counseling to the patient. The diagnosis of breast cancer during pregnancy or breastfeeding is a challenging situation considering the physiological changes. The first line of treatment is considered to be surgery indicated in any trimester of pregnancy, with mastectomy being often used. Chemotherapy can be offered, except for the first trimester, taking into account the risk of malformations. Radiotherapy, hormonal and biological treatment are contraindicated during pregnancy. The fetus must be evaluated regularly during treatment and the decision of delivery should be made on obstetrical and oncological indications.
