Yes, this can be a normal finding. Meaning that it is most likely a collection of fibrocystic tissue.
Breast tissue changes throughout the years and some women even experience this right before periods.
A mammogram with a sonogram was the correct procedure to do.
However, if it changes or gets larger please follow up with her, or if you notice any nipple discharge or change in the skin texture. Changes is what needs to be monitored.
Thanks for asking a good question!
I have had a hysterctomy - would you still expect this kind of change to take place. It has been growing for 2 months and very painful.
Yes, it could very well change with that.
Painful usually means it is fibrocystic. they can be very painful. Try to limit your caffeine intake, Take evening prime rose oil, this can also help decrease the pain.
However, again if it keeps getting larger then you need to be examined again. Usually in about 1 month.
Yes, Palpable masses just means that you can "feel" it but if they are normal the sonogram won't show up anything.
I have palpated many masses that are normal.
