Dramatic increase in volume versus length of invasive ductal carcinoma mimicking intramammary lymph node in a small nodular lesion.

Minor changes in size, density, and margin status of a lesion on serial mammograms are warning for breast cancer. Withal, a slight increase in lesion size in two dimensions can result in significant differences in volume. Therefore, comparative evaluation with previous mammograms and observing any difference in morphological features by screening are crucial for early diagnosis and optimal management of the disease.
