Updated On: 30-Jan-2026

A 55-year-old-woman presents to the physician's office for evaluation of mammographic findings on a screening mammogram. She denies any breast masses, nipple discharge, pain, or skin changes. Past history is pertinent for insulin-dependent diabetes. Family history is positive for postmenopausal breast cancer in her mother. She has a normal breast examination and no axillary adenopathy. A mediolateral oblique (MLO) view of the right breast is shown in the figure below.



Which of the following is the most appropriate next step in management?

  1. observation, with repeat mammogram in 612 months
  2. ultrasound
  3. biopsy
  4. lumpectomy, radiation therapy, and sentinel lymph node (SLN) biopsy
  5. total mastectomy

Answer(s): A

Explanation:

The mammographic appearance of popcornlike, coarse calcifications in the breast is characteristic of an involuting, or degenerating fibroadenoma in a postmenopausal woman. Mammographic follow-up is appropriate. A repeat study at 6 months would be considered if no prior films are available in order to assess stability of a new mammographic finding. Though ultrasound is often performed for solid masses, the amount of calcification in the mass would lead to artifact, making interpretation difficult. Biopsy would not be suggested based on the characteristic mammographic findings. Other surgical procedures would not be indicated
