FDG and Lactating Women

Lactating women have increased uptake in the breast(s) used for breastfeeding. For example, a breast that is consistently refused by baby or breasts in non-breastfeeding women, do not have significantly increased uptake.

No significant radiotracer is excreted in the breast milk, and the radiation dose received by the baby is more from close contact with the breast than from ingestion of radioactive milk.
