Some issues Dr. John J. Guido, MD can help you with:

Breast Biopsy

Breast biopsy is a procedure where a small sample of tissue is collected from the breast for testing. A physician may prescribe a breast biopsy for a variety of reasons, but they are most frequently prescribed for a lump found in the breast. Biopsy samples extracted are examined by pathologists in a laboratory setting and are tested to determine if they are cancerous or benign, or indicative of some other condition. Depending on the lab results, physicians may prescribe additional treatment. Other circumstances which may prompt a breast biopsy include:

Mammograms that detect other unusual features in the chest, such as a cyst or calcium deposit
Breast scans or ultrasounds that display abnormalities
Nipple changes, such as scaling, crusting, or bloody discharge

Breast biopsies are collected through several different procedures and the specific type of biopsy that a patient receives depends on the size, location, and features of a breast lump or irregularity. The three main methods of collecting a breast biopsy include:

Fine needle aspiration (FNA biopsy), where a thin needle is directed into a breast lump or abnormality, extracting a small sample of tissue or liquid
Core needle biopsy (CNB biopsy), where a hollow needle is directed into a breast lump or abnormality, extracting cylinders of tissue called "cores"
Open (surgical) biopsy, where a breast lump is removed through an incision in the breast

Fine needle aspiration (FNA) and core needle biopsy (CNB) are sometimes image-guided, where a mammogram, ultrasound, or MRI helps direct the physician performing the needle extraction.

Fine needle aspiration, the most common biopsy method, generally requires few patient preparations. It is recommended patients avoid using lotion, deodorant, and perfume prior to their biopsy procedure. FNA biopsy is performed with local anesthesia (topical numbing cream) and typically has a quick recovery, but patients may experience soreness for a few days. Core needle biopsy extracts slightly more tissue than an FNA biopsy.

Open (surgical) biopsy is more invasive and requires general anesthesia, where patients are put to sleep during the procedure. Patients must fast prior to the surgery. After the biopsy is performed, patients are monitored in a recovery room for a time before being discharged, when they will need someone else to provide transportation.

Although some may consider breast biopsy to be a simple procedure, it can catch critical issues - particularly breast cancer - that impact wellness. If a breast biopsy reveals an underlying condition like life-threatening cancer, patients can receive the diagnosis and medical treatment that is necessary for their long-term health.
