COVID-19 Vaccine Side Effects Trigger Mammogram Warning

Post vaccine side effects can mimic symptoms of breast cancer. KVLY's Bailey Hurley reports.

(KVLY/NBC News) — The COVID-19 vaccine is causing fear for some women, as their post-shot side effects are mimicking those of breast cancer.

Just a few days after Beth Nokken got her first dose of the covid vaccine, she woke up to unexpected lumps near her armpit.

“And one was the size of a golf ball. So that can be extremely concerning to someone,” Nokken says.

“Swollen lymph nodes are something that occurs as a body’s natural response to building up antibodies, or a response to a vaccine,” explains radiologist Dr. Allison Clapp.
