Needle Biopsy Gives Insight Into Breast Cancer Genetics

Breast tumor samples collected by a procedure called core needle biopsy provide an accurate snapshot of gene expression for the entire tumor, researchers say. The finding confirms the reliability of core needle biopsy as a method of breast cancer diagnosis and prognosis, the Swiss team reported in the journal Breast Cancer Research. In this study, researchers at the Women's University in Basel analyzed core needle biopsy samples collected from 22 breast cancer patients and compared those samples to surgical samples taken from the same women. In most of the women, the core biopsy and surgical sample revealed identical levels of expression of 60 genes known to be involved in breast tumor development. --Click the title of this post to read the full article from its source--
