Sentinel Lymph Node Biopsy: Risks
Content provided by Healthwise
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.
