Hi - I have been having pain in my left armpit for 2 weeks and my doctor suggested a breast ultrasound. There were enlarged lymph nodes found in both armpits - was wondering if this is worrisome as radiologist said they were benign and didn't need further testing. I had Covid in January and also shaved both my armpits recently. Also a cyst was found in the left breast. How soon should I go for repeat testing should it be one year or within a few months ? Should I also ask for a mammogram as radiologist did not suggest. My ultrasound in July was Birads 1 and now Birads 2 - does this require closer follow up.
