small oblong nodular density

interval change in small oblong nodular density in left breast.  Margins less well refined in the oblong nodular density in upper medial aspect of left breast.  This area was not noted in last mammogram on the written report which I received but noted on this mammogram as not concerned but now with the margins not as well refined want to do diagnostic mammogram and perhaps ultrasound.  Could losing a lot of weight and breast mass cause this change?

Dear Tp136, It is not unusual for a person to be asked to return for a more precise mammogram after a screening mammogram if there are any areas that may be of concern.  In general when a mammogram is read it is compared to the results of prior mammograms, which would help in the interpretation as to whether something seen in the current mammogram that had been evaluated and documented previously and is now unchanged.  A significant change in weight could make a difference in what is seen in a mammogram.
