What To Expect During Sentinel Node Biopsy
Saturday February 9, 2008
A sentinel lymph node biopsy is an important part of your breast cancer diagnosis and staging. Cancer cells from the tumor may spread to other parts of your body through your lymph system, and so checking on those lymph nodes will reveal whether or not any metastasis has occured. Learn what to expect during a sentinel lymph node biopsy, during recovery, and getting results.

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.
