How Does Sentinel Lymph Node Biopsy Work?
Published: May 07, 2024
A sentinel lymph node biopsy is a key procedure in determining the spread of breast cancer. Let's dive into how it works and why it's important.
What is a Sentinel Lymph Node Biopsy?
A sentinel lymph node biopsy (SLNB) is a surgical procedure that helps determine if breast cancer has spread to the lymph nodes. During the biopsy, surgeons locate and remove the first few lymph nodes into which a tumor drains. These nodes are then tested for cancer cells. If these nodes are cancer-free, it suggests that the cancer hasn't spread to other nodes.
Why is SLNB Important?
SLNB provides crucial information without the need for more extensive surgery. It helps doctors decide whether further procedures, like axillary lymph node dissection (ALND), are necessary. By focusing only on sentinel nodes, patients often experience fewer side effects, such as reduced risk of lymphedema, compared to more invasive procedures.
What Happens After SLNB?
If the sentinel lymph nodes show no signs of cancer, patients may not need additional lymph node surgery. However, if cancer cells are present, further treatment, like additional surgery or radiation, might be required. The results of SLNB guide the overall treatment plan, ensuring that it's as effective as possible.
