Breast Biopsy (cont.)

How does a physician confirm the presence of a breast growth?

A physician confirms the presence of a growth by taking a medical history (and asking numerous questions), performing a clinical examination that includes palpating (feeling) the breast, and interpreting the results of a diagnostic mammogram and sometimes other imaging studies such as ultrasound or MRI.

Ultrasound sends sound waves into the breast that "bounce" back to receiver that can record an image on a computer screen to visualize interior structures. This technique can help distinguish between a cyst and a solid growth. The physician may also order the laboratory analysis of any nipple discharge (other than milk) for the presence of cancerous cells. After confirming the presence of a suspicious growth, the physician orders a biopsy.

Is anesthesia needed for a biopsy?

For non-surgical biopsies, the patient may need no anesthesia at all or just a local anesthesia (one that numbs the suspicious area only). Sometimes, a patient receives a sedative (calming drug) with the local anesthesia.

For surgical biopsies, the patient may receive a local anesthesia (with or without a sedative) or general anesthesia (one that induces sleep). Patients requiring general anesthesia may have to fast 8 to 12 hours before undergoing a biopsy.

What about pain and complications?

Except for a minor sting from the injected anesthesia, patients usually feel no pain before or during a procedure. After a procedure, some patients may experience some soreness and pain. Usually, an over-the-counter drug is sufficient to alleviate the discomfort.

The risk of complications, such as infection and bleeding, is small for non-surgical procedures and slightly higher for surgical procedures.
