Lymph Node Surgery

About Lymph Node Surgery

Lymph node surgery covers a range of procedures used in cancer care to remove, sample, or evaluate lymph nodes to determine whether cancer has spread beyond the original tumor — a key factor in accurate staging and treatment planning. The most common approach is a sentinel lymph node biopsy, in which a tracer dye or radioactive marker identifies the first node(s) a tumor is likely to spread to; if these are clear, more extensive node removal can often be avoided, reducing the risk of complications such as lymphedema. When cancer is confirmed or suspected in multiple nodes, a more complete lymph node dissection — such as an axillary dissection for breast cancer or a neck dissection for head and neck cancer — removes a wider group of nodes from the affected region. These procedures are usually performed at the same time as the primary tumor surgery under general anesthesia, often using minimally invasive or robotic techniques to reduce scarring and speed recovery. Pathology results from the removed nodes guide decisions about whether chemotherapy or radiation is needed afterward, and physiotherapy or lymphedema-prevention guidance is provided as part of post-operative care.
