What Do Swollen Lymph Nodes Under The Armpits Indicate?
Cyclical nature suggests benign conditions!
Detailed Answer:
Hi and thanks so much for this query.
I am so sorry to hear about this disturbing information regarding your lymph nodes. The bilateral nature cyclical variation suggests that this is probably caused by a benign condition than a malignant one. If this were caused by cancer, they will never regress and they will hardly affect both sides at the same time unless it is cancer that is evident to everyone.
I think you really don't need a biopsy at this time. I also think you don't need to see a lymphologist(Lymph node specialist) at this time. My recommendations is to take a detailed report of when this happens, time and relation to your cycles(like you suggested), activities, etc. We will review to see if it fits squarely into any pattern or may suggest something worrisome that warrants further evaluation.
Am a bit curious and will like to know what makes you feel so disturbed about this: Pain? Swelling? Fear of some other disease conditions? etc.
I hope this guides and helps. I wish you well. Feel free to follow up with me if need be.
