Is Y 90 Safe in Breastfeeding

I am a breastfeeding mother and i want to know if it is safe to use Y 90? Is Y 90 safe for nursing mother and child? Does Y 90 extracts into breast milk? Does Y 90 has any long term or short term side effects on infants? Can Y 90 influence milk supply or can Y 90 decrease milk supply in lactating mothers?

Information in this record refers to the use of yttrium Y-90 microspheres as therapeutic agents. No information is available on the use of yttrium Y-90 microspheres during breastfeeding. However, little (with resin) or no (with glass) yttrium Y-90 attached to microspheres is available to the systemic circulation of the mother after administration via the hepatic artery, and doses less than 17 GBq do not appear to require withholding of breastfeeding.[1] In a study in which external radiation was measured after 143 administrations (124 resin, 19 glass) to 86 patients, only one exceeded the threshold for concern with close infant contact, using conservative methods.[2] Mothers concerned about the level of radioactivity in their milk could ask to have it tested at a nuclear medicine facility at their hospital. When the radioactivity is at a safe level she may resume breastfeeding. A method for measuring milk radioactivity and determining the time when a mother can safely resume breastfeeding has been published.[3]
