Sentinel Lymph Node Biopsy

Biopsy, Sentinel Lymph Node

Risks

It is possible to have some problems after a biopsy. Your doctor will give you instructions on what to do if a problem occurs.

• Bleeding from the biopsy site. This risk is higher for people who have bleeding problems or who take blood-thinning medicines. If you are at risk for bleeding, you may be given blood clotting factors before the biopsy.
• Skin numbness at the biopsy site
• Infection at the biopsy site
• Swelling and fluid buildup at the biopsy site. This is less likely after a sentinel node biopsy than if more lymph nodes are taken out (axillary dissection).
• Lymphedema, which is swelling of the whole arm. This can happen soon after the biopsy or months or years later. This is less likely after a sentinel node biopsy than an axillary dissection.
• Problems from general anesthesia, if it is used
• Damage to nerves at the biopsy site. This may cause weakness or pain.
