RisksBy Mayo Clinic staff
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 your breast heals
- Additional surgery or other treatment, depending on biopsy results
Contact your doctor 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.
