What Are the Risks and Complications of a Lymph Node Biopsy?

While a lymph node 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 pain or discomfort at the biopsy site, which can usually be managed with over-the-counter pain relievers.
  • Bruising and Swelling: Mild bruising and swelling around the biopsy site may occur.
  • Nerve Damage: Rarely, the biopsy may cause damage to nearby nerves, leading to numbness or tingling.
