In 2014 a breast ultrasound showed a enlarged lymph node in armpit. was told to watch it. i still feel it. what to do?

Bothering you? Mammo: 1st, perform (& have doctors perform) serial breast examinations (BSE). Breast health's important, since breast cancer can often present as an enlarged armpit lymph node. 2nd, get mammograms every 2 yrs. It's an accepted screening tool by USPSTF. 3rd, if it bothers you for other reasons (size change, tenderness, clothing), talk to a surgeon about removal & biopsy. It's the only way to know 4 sure
