Which of the following are possible complications after a breast biopsy?

After a breast biopsy, several complications can arise, including allergic reactions, hematomas, and infections. Choosing "all of the above" encompasses these potential complications, acknowledging that they can each occur during or after the procedure.

An allergic reaction to the local anesthetic can happen, though it is relatively rare. Some patients may have sensitivities or allergic responses that develop following exposure to anesthetics, leading to symptoms such as rash, swelling, or other systemic reactions.

Hematomas are another potential complication. This occurs when blood accumulates outside of blood vessels and can create a painful swelling in the breast area following the biopsy. Hematomas can form if blood vessels are inadvertently damaged during the procedure.

Infection is also a concern after a biopsy. Any time the skin is penetrated, there is a possibility for pathogens to enter the body, which can lead to localized or systemic infections. Signs of infection may include increased redness, swelling, warmth, and discharge at the biopsy site.

By including all these possible complications, the correct choice reflects a comprehensive understanding of the risks associated with breast biopsy procedures, which is crucial for patient awareness and management.
