We usually know that pregnant women should try to avoid receiving X-rays and CT examinations because X-ray radiation is a certain teratogenic risk to the fetus, but orthopedic surgeons also often encounter women who have just given birth and are still breastfeeding and need to do the above examinations. Some doctors don’t recommend it because they think it will interfere with breastfeeding and is not good for the baby; some recommend to stop breastfeeding for 24 to 48 hours after the test and then start breastfeeding again. I was troubled by this question: Can a breastfeeding woman have an X-ray or CT scan? Do you need to stop breastfeeding for a while after the test? Occasional low-dose general radiological examinations in breastfeeding women will not have any effect on the body. Although there is some ionizing radiation associated with medical x-rays, the negative effects of occasional small amounts of radiation on adults are almost zero. After exposure to x-rays, your body carries radiation, and these radiation particles last for about three months before they dissipate in your body, but the measurements are minimal and generally do not cause harm. Even the contrast agents that are pumped into the body in enhanced CT and enhanced MRI do not have much effect on breastfeeding, and in 2001 the American College of Radiology concluded, “We have sufficient evidence that breastfeeding women can continue to breastfeed after the application of these contrast agents.” Therefore, if a breastfeeding woman needs to have an X-ray or CT examination due to her condition, she can go ahead and do it without fear; nor do she need to stop breastfeeding for 24 or 48 hours for this purpose, and some foreign literature even emphasizes that it is not necessary to stop for 1 second. So we have to weigh the pros and cons and not over imagine exaggerating the negative effects of these exams on the body, much less on breastfeeding.
