Lisa Mullen, M.D., a radiologist that specializes in breast imaging, offers some perspective and answers her questions.

Getting the COVID-19 vaccine can cause temporary lymph node enlargement and result in a “false positive” mammogram.

The COVID-19 vaccine, like various other vaccinations, can cause a short-term enlargement the lymph nodes. This can reason your mammogram to appear abnormal also when you space OK and also there is no clues of cancer.

But, enlarged lymph nodes can an outcome in a “false positive” on your mammogram. Girlfriend may get a request to return for further testing — a call-back — which can be unsettling.

The COVID-19 Vaccine and also Enlarged Lymph Nodes

How execute vaccines such as the COVID-19 vaccine impact lymph nodes?

Not every vaccines cause swollen lymph nodes, however ones that cause a an ext intense immune response, such as the COVID-19 vaccine, part shingles vaccines, and also others, are more likely to influence them. “The COVID-19 vaccine is a new kind of vaccine, and people space reacting strongly to it,” Mullen says. “That heightened immune response is normal and also expected.”

For human being getting a two-part coronavirus vaccine (such as the Moderna or Pfizer type), is lymph node enlargement much more likely after the second shot?

Mullen claims that larger lymph nodes can appear after the very first or 2nd vaccination.

Is COVID-19 vaccine lymph node enlargement permanent?

No, Mullen says. Her lymph nodes will return to normal dimension a couple of weeks after your vaccination regimen is complete.

Can other vaccines cause lymph node alters on a mammogram?

Yes. Mullen says, “Other vaccines the activate the immune device can adjust the appearance of your lymph nodes, such as the shingles shot, the pneumonia shoot or the diphtheria/tetanus/pertussis (D-TaP) shot. Getting an ext than one vaccination at a time can cause a more prominent immune response, such as if you get a flu shot at or near the same time as secondary vaccine.”

She add to that even the yearly flu shoot can influence the lymph nodes. “Every year, flu vaccine season coincides with chest cancer awareness month, so some patients are gaining mammograms as soon as they have actually enlarged nodes due to the flu shot.”

And the not just one follow-up. “At the return appointment, we perform an ultrasound that the underarm, get a medical background and measure the lymph nodes,” Mullen says. “After that, the patient needs to follow up with one more ultrasound in three months so we can make sure the nodes go back to normal size.

“Abnormal-appearing lymph nodes top top a mammogram can set off a chain of testing that is expensive and also anxiety-producing.”

She claims that extra call-backs as result of temporary results of the COVID-19 vaccines can impact patient scheduling at mammogram clinics. Once patients call for two follow-ups or a biopsy to ensure your lymph nodes room OK, it can make it tougher for various other patients to obtain timely appointments.

Mullen says that numerous who are an initial in heat to obtain COVID-19 vaccinations — larger women, health treatment workers, teachers and also others — space over age 40 and therefore recommended because that yearly screening mammograms.

She recommends, “If you’ve already had one or both COVID-19 shots, us recommend scheduling screening mammograms 4 to six weeks ~ the last shot, since your lymph nodes can become enlarged from the vaccine and may take a while to go down. In this case, it’s OK to hold-up your mammogram.

“However, if girlfriend have any kind of symptoms such as breast pain, a chest lump, nipple discharge or a doctor referral saying you require a diagnostic mammogram, don’t delay: acquire the test.”
