Wire Localization



Breast surgical biopsy is surgery to remove all or part of a breast mass. A lab will check the sample to see if there is something unusual about it.

  • Bleeding
  • Infection
  • Bruising
  • Damage to tissues

Things that may raise the risk of problems are:

  • Smoking
  • Long term conditions such as obesity or diabetes
