COVID vaccinations could prompt false positive readings of mammograms

As more and more people get vaccinated against COVID-19, more potential side effects have emerged. One is swollen lymph nodes and while that's what you'd expect when an immune response is triggered, it's exactly what you don't want to see when screening for breast cancer.

Dr. Jessica Burgers, a breast surgeon specializing in hematology oncology at Holy Cross Hospital in Fort Lauderdale, Florida, knows exactly what to look for when screening for cancer. "One of the things that's a tipoff for cancer in the lymph nodes is if the lymph nodes are looking swollen or enlarged," Burgers explained to CBS Miami.
