I just worked with a mother who experienced a very sudden lump in her breast just below the nipple. No redness no pain, but rather large and quite sudden in appearance. She saw a surgeon who did a needle aspiration and drew of 60 CC of lymph fluid from a cyst (no milk in it). Mother said she felt a coolness after it was drained but no pain and is able to pump and breastfeed (she does both at different times during the day) without discomfort. She has a hx of cystic breasts. This is another possiblity you might wish to check out.
