These three biomarkers help doctors choose the best treatments for individual women. Therefore, tumors that recur in the breast or appear elsewhere in the body should be biopsied “as a routine procedure” because the results may influence treatment decisions, recommended the authors led by Dr. Linda Lindström of Cancer Center Karolinska in Sweden.
