Risks

Risks associated with a breast biopsy include:

• Bruising and swelling of the breast
• Infection or bleeding at the biopsy site
• Altered breast appearance, depending on how much tissue is removed and how the breast heals
• Additional surgery or other treatment, depending on biopsy results

Contact your health care team if you develop a fever, if the biopsy site becomes red or warm, or if you have unusual drainage from the biopsy site. These can be signs of an infection that may require prompt treatment.
