Do chronic swollen lymph nodes in the arm pit most likely mean breast cancer?

May need biopsy.....: If the lymph nodes are persistent after seeing your doctor and being evaluated for a possible infection and perhaps being treated with a course of antibiotics, a consultation with a breast cancer surgeon may be needed. Also, a proper breast exam with your doctor, mammogram and ultrasound should be performed if not already.

1of many reasons.: Lymph nodes may become enlarged due to many different reasons, of which cancer is but one explanation. The first step is to be seen by your doctor who will perform a careful breast exam and order a diagnostic mammogram and ultrasound. Based upon these findings, an ultrasound-guided biopsy of one of the lymph nodes may be ordered.

No: This would not be the first thing that i think of. Could be related to infection. You should tell your friendly primary care physician about these symptoms.

On the list: But no where near the top. A local infectious or inflammatory process would be more likely. Indolent lymphoma and breast cancer possible but unlikely. Get it checked out.
