Too many women with abnormal mammograms or other breast problems are undergoing surgical biopsies when they should be having needle biopsies, which are safer, less invasive and cheaper, new research shows.

A study in Florida found that 30 percent of the breast biopsies there from 2003 to 2008 were surgical. The rate should be 10 percent or less, according to medical guidelines.

The figures in the rest of the country are likely to be similar to Florida’s, researchers say, which would translate to more than 300,000 women a year having unnecessary surgery, at a cost of hundreds of millions of dollars. Many of these women do not even have cancer: about 80 percent of breast biopsies are benign. For women who do have cancer, a surgical biopsy means two operations instead of one, and may make the cancer surgery more difficult than it would have been if a needle biopsy had been done.

The reason for the overuse of open biopsies is not known. Researchers say the problem may occur because not all doctors keep up with medical advances and guidelines. But they also say that some surgeons keep doing open biopsies because needle biopsies are usually performed by radiologists. The surgeon would have to refer the patient to a radiologist, and lose the biopsy fee.

A surgical biopsy requires an inch long incision, stitches and sometimes sedation or general anesthesia. It leaves a scar. A needle biopsy requires only numbing with a local anesthetic, uses a tiny incision and no stitches and carries less risk of infection and scarring.
