When her obstetrician-gynecologist recommended a mammogram, Emily Legg didn’t hesitate to schedule an appointment for the screening.
Her grandmother had been diagnosed with breast cancer and her father died of prostate cancer in his mid-50s. Ms. Legg also has polycystic ovary syndrome (PCOS), which increases the risk of some cancers.
Having just turned 40, Ms. Legg said she was determined to be as proactive as possible with cancer screenings.
Before the mammogram, she arranged for childcare for her 6-month-old daughter and filled out a required questionnaire online that asked about her history and health conditions. When the appointment day arrived, Ms. Legg made the 30-minute drive to the clinic where she was prepped for the procedure and escorted to the mammography room.
But just before the screening started, Ms. Legg happened to mention to the technician that she was breastfeeding. The surprised tech immediately halted the procedure, Ms. Legg said. Because of increased breast density caused by nursing, Ms. Legg was told to wait at least 6 weeks after weaning for a mammogram.
“I didn’t even consider that breastfeeding might prevent me from getting a mammogram,” said Ms. Legg, a writing professor from Hamilton, Ohio. “I had to go home. I was frustrated, mostly because I had driven all that way. I had hyped myself up. I had childcare in line. And now I had to wait until my daughter weaned? At the time, I didn’t know if my daughter was going to breastfeed for 2 years or be done at 6 months.”
Considering her family background, Ms. Legg worried about not receiving the screening. Her sister had recently undergone a mammogram while she was breastfeeding without any problems.
When she did research, Ms. Legg found conflicting information about the subject online so she turned to Reddit, where she started a thread asking if other moms over 40 had experienced similar issues. Dozens of moms responded with questions and concerns on the subject. Some wrote about being denied a mammogram while breastfeeding, while others wrote they received the procedure without question. Guidance from health professionals on the topic appeared to vastly differ.
“That’s why I turned to [social media] because I wasn’t finding anything else,” Ms. Legg said. “There’s just a lack of clear information. As an older mom, there’s less information out there for being postpartum and being over 40.”
Confusion over screenings during breastfeeding comes at the intersection of national guidelines lowering the recommended age for first mammograms, more women having babies later in life, and women getting breast cancer earlier.
Most physician specialty associations agree that mammography is safe for breastfeeding patients and that they need not delay routine screenings. However, the safety of breast imaging during pregnancy and lactation is not well advertised, said Molly Peterson, MD, a radiologist based in St. Frances, Wisconsin, and lead author of a 2023 article about breast imaging during pregnancy and lactation in RadioGraphics, a journal of the Radiological Society of North America.
Conflicting information from nonscientific resources adds to the confusion, Dr. Peterson said. At the same time, health providers along the care spectrum may be uncertain about what imaging is safe and reasonable. Recommendations about mammography and lactation can also vary by institution, screening experts say.
“I’ve talked with pregnant and breastfeeding patients, both younger and older, who were unsure if they could have mammograms,” Dr. Peterson said. “I’ve also fielded questions from technologists, unclear what imaging we can offer these patients. ... Educating health professionals about evidence-based guidelines for screening and diagnostic imaging and reassuring patients about the safety of breast imaging during pregnancy and lactation is thus more important than ever.”
Differing Guidelines, Case-by-Case Considerations
The RadioGraphics paper emphasizes that both screening and diagnostic imaging can be safely performed using protocols based on age, breast cancer risk, and whether the patient is pregnant or lactating.
The American College of Radiology (ACR) Appropriateness Criteria also support mammography for certain patients during lactation. The guidelines state there is no contraindication to performing mammography during lactation, but note that challenges in evaluation can arise because of the unique physiological and structural breast changes that can occur.
“Hormones can change breast density and size of the breast, which could limit the clinical examination, mimic pathology, and obscure mammographic findings,” said Stamatia V. Destounis, MD, FACR, chair of the ACR Breast Imaging Commission. “It is important the patient pumps right before the mammogram or brings the baby to breastfeed prior to the imaging examination to offer the best imaging evaluation and reduce breast density as much as possible.”
In those patients who choose to prolong breastfeeding and are of the age to be screened, it is important they undergo yearly clinical breast exams, perform breast self-exams, and discuss breast cancer screening with their healthcare provider, she said. “They should not delay a routine screening mammogram. Most patients have dense breast tissue at this time, and frequently a breast ultrasound may be performed also.”
The American College of Obstetricians and Gynecologists (ACOG) does not have specific guidelines about breastfeeding mothers and mammography recommendations. Breastfeeding patients should discuss with their physicians or midwives the pros and cons of mammography, taking into account personal risk factors and how long they plan to nurse, said Joshua Copel, MD, vice chair of obstetrics, gynecology and reproductive sciences at Yale Medicine, New Haven, Connecticut, and a member of ACOG’s Committee on Obstetric Practice.
“The question for anybody to address with their physician will be, ‘Is my risk of breast cancer high enough that I should take that small risk that they’re going to over- or underread the mammogram because of my nursing status? Or should I wait until I wean the baby and have the mammogram then?’” he said.
Institutional and practice protocols meanwhile, can depend on a patient’s cancer risk.
Guidelines at the University of Wisconsin, for instance, advise that lactating patients 40 or over who are at average risk, wait 6-8 weeks after cessation of breastfeeding, said Alison Gegios, MD, a radiologist and assistant professor in breast imaging at the University of Wisconsin School of Medicine and Public Health. Average risk is defined as less than a 15% lifetime risk of breast cancer, she said.
Dr. Gegios, a coauthor on the RadioGraphics paper, said her institution recommends screening mammography if lactating patients are at intermediate or high risk, and are over 30. In such cases however, screening is generally deferred until 3-6 months after delivery, she noted.
“If patients are high risk, it’s also important to do screening breast MRIs,” Dr. Gegios said. “Studies have shown that screening breast MRIs are effective in breastfeeding patients despite their increased background parenchymal enhancement because breast cancer still stands out on our maximum intensity projections and stands out on the exam from the background.”
How to Clear Up Confusion, Promote Consistency
After her experience at the mammography practice, Ms. Legg went home and immediately sent a message to her ob.gyn. about what happened.
The doctor was similarly surprised and frustrated that Ms. Legg wasn’t able to get the mammogram, she said. To get around the difference in protocols, Ms. Legg’s ob.gyn. referred her to a high-risk clinic in Cincinnati. Ms. Legg’s history qualified her as high risk and she received genetic testing and a breast ultrasound at the clinic, she said.
“The ultrasound showed some shady spots,” Ms. Legg recalled. “They weren’t quite sure what they were. Another ultrasound later, they determined the spots were symmetrical and it ended up not being anything [serious]. Genetic-wise, I did not have any markers for cancer.”
Ms. Legg was relieved and she eventually received a mammogram when she finished breastfeeding, she said. However, she feels the overlap of older, breastfeeding moms and mammography guidelines deserves more attention.
“I would encourage all of us in the ‘geriatric mother’s club,’ to advocate for yourself, do your research, and also turn to your medical professionals and ask questions,” she said. “Make sure you know what they recommend for moms who are older and just had a baby.”
On the provider side, Dr. Destounis said physicians should revisit with patients the most updated guidelines about breastfeeding and mammography at routine appointments.
“Patients and their physicians have to have communication about screening for breast cancer if they are of screening age,” she said.
Dr. Copel advises physicians to run through the risks and benefits of mammograms with older, breastfeeding patients and make a shared decision. “It’s all going to vary with the individual circumstances,” he said. “If someone [has] a BRCA gene and their sister and mother had breast cancer, maybe it’s worth it. If somebody has absolutely no family history and just crossed the threshold for meeting a mammogram [recommendation], then sure, wait.”
Ms. Legg would like to see more professional literature and educational material directed toward the older, breastfeeding population about mammograms.
“At minimum, work together across departments to create an intake form, a questionnaire that is inclusive of everything,” she said. “There should be a question before you even get to the tech that asks, ‘Are you breastfeeding?’ ”
