I thought I read that delaying mammograms for several weeks after vaccination is recommended so there is no confusion about lymph node swelling being from vaccination vs. disease since ultrasound or mammography can’t tell if a lymph node is reactive vs, neoplastic (unless there is another mass present).
Yeah, she has to wait another month. Her second shot was about a month ago. But the lump appeared last week, so the doctor is unsure if it's related. She did develop swollen lymph nodes under her arm about a week after the first shot. She got the Moderna series.
