Very Low Risk

Safe. Compatible. Minimal risk for breastfeeding and infant.

Mammographies, like any x-ray, do not contraindicate breastfeeding because the radiation neither stays in the breast nor is excreted in the milk.

Breastfeeding, as with small or very large breasts, can make reading a mammography difficult (Robbins 2011, Gregl 1977), in which case ultrasound can be used (Sabate 2007).
There is not always an increase in density or reading difficulties in breastfeeding mothers (Swinford 1998).
Emptying the breast (breastfeeding) just before can help to reduce the discomfort of the examination and facilitate its reading.

Mammographies do not alter prolactin levels (Saraç 2008).

The different contrasts for these explorations (iodized or not) are compatible with breastfeeding because they are inert, metabolize quickly without releasing iodine, are not excreted in milk and are not absorbable orally (Cova 2014, Tremblay 2012, Wang 2012, Newman 2007, Webb 2005, Nielsen 1987).

Following a radiological examination, even with iodinated contrast or not, it is not necessary to wait before breastfeeding (Mitchell 2019).

Suggestions made at e-lactancia are done by APILAM team of health professionals, and are based on updated scientific publications. It is not intended to replace the relationship you have with your doctor but to compound it. The pharmaceutical industry contraindicates breastfeeding, mistakenly and without scientific reasons, in most of the drug data sheets.

Jose Maria Paricio, Founder & President of APILAM/e-Lactancia

Your contribution is essential for this service to continue to exist. We need the generosity of people like you who believe in the benefits of breastfeeding.

Thank you for helping to protect and promote breastfeeding.
