While a rectal biopsy is generally safe, it carries some risks and potential complications, including:
- Bleeding: Mild bleeding at the biopsy site is common, but significant bleeding is rare.
- Infection: There is a small risk of infection at the biopsy site.
- Pain and Discomfort: Some patients may experience mild pain or discomfort during or after the procedure, which usually resolves quickly.
- Perforation: Rarely, the procedure may cause a tear (perforation) in the rectal wall.
- Reaction to Anesthesia: If sedation or anesthesia is used, there is a risk of adverse reactions.
