Non-Surgical Technique for Diagnosing Breast Cancer Nearly as Effective as Surgical Biopsy New Study Finds

New Technique Being Praised For Diagnosing Breast Cancer

Different methods of minimally invasive biopsy for breast cancer are nearly as accurate as surgical biopsy but have much less risk of harm to patients, according to a new report release late last week. The report states comparative information between traditional surgical biopsies with various types of needle biopsies involving removal of tissue through a large hollow needle inserted through the skin. The same report will also provide information so that doctors and patients can work together to make the best possible diagnostic choice for each individual patient.

Based on reviews in several scientific journals, the risk and impact of core needle biopsy on patients could distinguish between malignant and benign lesions approximately as accurately as open surgical biopsy, which is commonly considered the “gold standard” method of evaluating suspicious lesions. Core needle biopsies have a much lower risk of severe complications than open surgical procedures, researchers found. Reports also found that women who are initially diagnosed with breast cancer by surgical biopsy are more likely to undergo multiple surgical procedures during treatment than women who are initially diagnosed with breast cancer by core needle biopsy.

Open surgical biopsies, which involve removing a sample of tissue from the suspicious area through a surgical incision, are highly accurate. The procedure may be performed under general anesthesia, sedation plus local anesthesia, or local anesthesia only. But, while generally considered safe, open surgical biopsies are surgical procedures that, like all surgeries, carry a small amount of risk. Given that only a fraction of women who undergo breast biopsy procedures are diagnosed with cancer, use of traditional biopsy leads to large numbers of women who do not have cancer undergoing an invasive surgical biopsy.
