Although swollen lymph nodes can be asign of cancer, doctors are cautioning people who have recentlyreceived the COVID-19 vaccinenot to jump to any conclusions, as it’s also a common response to vaccination.
Last month, radiologists at Massachusetts General Hospital noted that although “swelling of lymph nodes in the armpit is anormal responseto COVID-19 vaccinations” on mammograms “they can be mistaken for nodes that are swollen because of cancer. "
In order to prevent unnecessary confusion or fear — while still encouraging patients to keep up with their health care needs — radiologists at Massachusetts General Hospital have come up with a set of guidelines, which they published last month.
“We had started to see more patients in our breast imaging clinic with enlarged lymph nodes on mammography, ultrasound, and magnetic resonance imaging. And we noticed they were coming to our clinic after a recent COVID-19 vaccination,” Dr. Constance Lehman, director of Breast Imaging at MGH said in a statement. “We talked with our colleagues in primary care and in our breast cancer specialty clinics and realized we needed a clear plan for management.”
One important aspect is communication, with radiologists suggesting that patients should be notified via letter that “enlarged lymph nodes are common after the COVID-19 vaccine,” and that the lymph nodes on the side where patients received the vaccine will appear larger.
The letter should also communicate that patients should take action if the swelling persists for over six weeks.
Additionally, so long as the patient has no other health concerns, the radiologists do not recommend that any additional imaging or biopsies be performed unless the lymph nodes remain swollen for more than six weeks.

Although health experts stress that urgent imaging should not be delayed due to vaccination, more routine examinations can bedelayed for 6 weeksafter patients receive their final dose.
“If possible, and when it does not unduly delay care, consider scheduling screening exams prior to the first dose of a COVID-19 vaccination or 4-6 weeks following the second dose of a COVID-19 vaccination,” theSociety of Breast Imagingwrote in their own list of recommendations.
A recent article published in thejournal Radiologyalso noted that patients should make sure they get both doses in the same arm.

While speaking withThe New York Times,Dr. Lehman noted that patients currently being treated for cancer in one breast should not get their vaccination on the same side.
“I also want cancer patients to know they can get the vaccine on the opposite side or even the leg to avoid confusion,” Lehman added.
