About the symptom

A breast lump is a mass that develops in the breast. Any new breast lump should be evaluated by a physician as soon as possible. A breast lump can feel like a rock in the breast or a sponge in the breast or anything in between. It can feel smooth or lumpy or grainy and be movable or not movable. Most breast lumps will turn out to be benign (not cancer). The decision to biopsy the lump is dependent on many factors, but usually some sort of X-ray or Ultrasound will be used to evaluate the lump.
