X-rays, CT scans and other X radiations, such as mammography that are done to a mother do not affect the human milk or breastfeeding. X rays used neither remain in the body nor are excreted in the milk.The X radiation does not alter Prolactin levels. The various contrasts used for these scans (whether Iodine or not) are compatible with breastfeeding because they are biologically inert, undergo a very rapid body clearance without iodine released particles and not excreted in the milk. Furthermore, it cannot be orally absorbed by the infant.You can consult one by one of them, by searching on a particular name. After a radiological examination, even with iodinated contrast, it is not necessary to transiently withheld nursing.You may search for Mammography under its proprietary name. Avoid unnecessary testing (as they use radiation emissions). A number of dye materials (iodine based or not) used for diagnosis imaging procedures (x-Ray, CAT scan, MRI) are compatible with breastfeeding since they are inert, metabolize rapidly without leaving free iodine and are not or very little absorbed by the gastrointestinal tract. Look after diverse dyeing material being used. See below the information of these related products: See below the information of these related groups: X-Ray Contrast Media, Iodinated.
