Breast lump or breast changes: Early evaluation is essential

Imaging tests

Learning more about a breast lump may involve:

  • Diagnostic mammogram. This specialized breast X-ray shows breast changes. It takes X-ray pictures from several angles.
  • Breast ultrasound. Sound waves show pictures of the inside of the breast on a screen. Ultrasound imaging can show whether a breast lump is solid or filled with fluid.
  • Breast MRI. An MRI uses a magnet and radio waves to make pictures of the inside of a breast. A breast MRI may help when the diagnosis isn't clear. Before a breast MRI, you might have a dye put into a vein in an arm. The dye helps tissues and blood vessels show up better on the MRI pictures.
