I have pain & swelling in my left armpit. no injury & nothing visible on skin. should i see my breast surgeon or wait until my next f/u appt in sept?

Call and ask: If you are unsure of how to proceed, most physicians would prefer that you call the office and ask advice. They know your medical status, which we do not and they can offer better advice. Best wishes..

If there is: Pain and swelling you may have an infection. It could also b reactive breast tissue changing do 2 hormone fluctuations. If its not subsiding i would get seen sooner but it's likely not a cancer due to ur age and the presentation. Good luck.

Most likely a cyst: @ ur age & no strong history of breast cancer, this is most likely a cyst as nodes from malignant disease r usually not painful. But 4 peace of mind i would have it looked at now. Tell ur gyn & report this change in ur health 2 him/ her & get in 4 an evaluation. Sometimes if u tell that all u want looked @ is the lump u may b able 2 cn quickly & still keep ur regular appointment.
