Doctors: Wait 4-6 weeks after COVID-19 vaccine to get mammogram

PHILADELPHIA (KYW Newsradio) — Medical experts are recommending women put some time in between getting the COVID-19 vaccine and getting a mammogram.

KYW Medical Editor Dr. Brian McDonough said headaches, chills, fever and swelling of lymph nodes can sometimes be side effects of getting the COVID-19 vaccine.

“What the vaccine is doing is it's causing an immune reaction, faking your body into thinking you were exposed to COVID. That's kind of how the immune reaction works,” he explained.

He said it may take some time for lymph node swelling under the arm, where the shot is given, to go down, which is why doctors want women to wait four to six weeks before getting a mammogram after getting their vaccine.

“When we do mammograms on women, if we see a lymph node, we're concerned. That's something that may lead to a biopsy or other tests, because we saw that node,” McDonough said.

And those extra, unnecessary tests or potential misdiagnosis are things experts want to take off the table.

McDonough added another option for women planning on getting a mammogram is to schedule one before they get the vaccine.
