Do I need a surgical biopsy after a stereotaxic core biopsy?

I've just completed a stereotaxic biopsy for both breasts and the diagnosis are as follows:

  Right breast, upper outer quadrant: Atypical ductal   hyperplasia, with microcalfications

  Left breast, upper:  Atypical ductal hyperplasia, with microcalcifications and columnar cell alteration with apical secretions(CAAPS).

The right breast has the similiar findings from both needle and surgical biopsy in April 1998.

Would you kindly advice me if I need further biopsy to comfirm the diagnosis?  What does the result tell, in terms of my risk for DCIS?

Dear cbgsc, A finding of atypical hyperplasia is looked at as a risk factor for development of breast cancer (or Ductal Carcinoma In Situ [DCIS]).  We don't know if it means that atypical hyperplasia leads to cancer or that the conditions that allow atypical hyperplasia to be present also would let cancer (or DCIS) be present.  

Close follow-up is the usual recommended course of action, this is in order to find an intraductal cancer (DCIS) or invasive cancer at an early stage. This would include physical examination by a doctor every six months, and yearly mammograms.  If you have not sought a consultation with a breast specialist, you may want to do so.  They could evaluate, advise and recommend a plan for follow-up and surveillance, specific to you.  

Whether a surgical biopsy is necessary would be through evaluation of all testing, and whether there was concern that an adequate sample of the area was not obtained.
