I am 56 and was diagnosed with Mastitis in right breast. What causes that at my age? After a round of antibiotics, the redness was gone but the pain and swelling was still there. I was finally sent for a mammogram (the pain was so bad I was screaming and crying), diagnostic mammogram, and ultrasound. The mammogram came out ok, but the ultrasound show a build-up of fluid in a duct. When the needle aspiration was done 4 days ago, the doctor could not completely get all the fluid out as it was very thick and wouldn't go up the needle. The fluid was yellow and bloody. Is that significant? Also, how long does it take for the fluid to be analyzed. The doctor said that it may not be enough and if that is the case, then I would have to come back in for another procedure.
Is there a reason to worry about the appearance of the fluid and what would the next step be?
