In Office Biopsy

So, you’ve been told you need a breast biopsy. There are many types of breast biopsies available. Which type you receive depends on how the lesion is best seen and how large it is. The two main types of biopsies are excisional and percutaneous core biopsies. An excisional biopsy entails going to the operating room to surgically remove the entire lesion. The downside of this type of biopsy is that you are unsure of the diagnosis prior to removing the tumor. Therefore, a suboptimal surgery may be performed, possibly requiring a second operation. A percutaneous biopsy can be performed by either a surgeon or a radiologist. It can be done under ultrasound, mammographic, or MRI guidance. First, local anesthesia is used to numb the area. Then a needle is placed in the nodule/calcifications to sample the abnormality. The tissue removed is sent to the pathologist and the results are ready in two to three business days. A two-millimeter titanium marker is placed at the site of biopsy for possible future localization purposes. 

The percutaneous biopsy itself takes fifteen minutes to an hour, depending on which method of guidance is utilized. You could drive yourself to this procedure and return to your daily activities almost immediately. Possible side effects include, but are not limited to bleeding, infection, and breast implant rupture.
