Cisplatin and breast feeding
Most sources consider breastfeeding to be contraindicated during maternal antineoplastic drug therapy, especially alkylating agents such as cisplatin. Excretion of platinum into milk occurs, but results from 3 cases are inconsistent. The exact form and toxicity of platinum excreted into breastmilk are also not known. The nursing infant would receive any platinum compounds orally rather than intravenously and oral absorption of oral platinum compounds by infants is not known. Chemotherapy may adversely affect the normal microbiome and chemical makeup of breastmilk. Women who receive chemotherapy during pregnancy are more likely to have difficulty nursing their infant.
