Varreduras de diagnóstico (raios X, mamografias, ressonância magnética, e CT/CAT)

In her article Breastfeeding and Cancer1, Diane West, BA, IBCLC, writes that radiation from diagnostic procedures using x-rays, mamografias, ressonância magnética, and CT/CAT scans are all safe during lactation. While this kind of radiation does have the ability to mutate DNA in live cells, it does not collect in the milk and is therefore compatible with uninterrupted breastfeeding. Radiopaque e radiocontrast agents typically used in ductogram, CT/CAT, ressonância magnética, MIBI scan, or PET scan diagnostic tests are extremely inert and virtually unabsorbed when taken orally, so they do not pass into the milk and it is not necessary to interrupt breastfeeding when they are used. Additionally, O livro de respostas da amamentação2 reports that nursing may safely resume immediately after X-rays. Lactating people who receive iodinated contrast or gadolinium can continue breastfeeding without interruption.3

Although the vast majority of circumstances do not require interruption of breastfeeding, certain exceptions do exist.4 More information on the safety of radiocontrast dyes can be found in Thomas Hale’s Medications and Mothers Milk.5 6 Radioactive isótopos are not safe while breastfeeding, and breastfeeding should be temporarily interrupted when having a procedure requiring these isotopes. Generally, a short interruption of breastfeeding is necessary and a baby should be fed previously pumped milk.7

Por favor divulgar any diagnostic scans you may undergo to a recipient family in order to allow for their full informed choice process.
