Lymph node dissection, also known as lymphadenectomy, is a crucial surgical procedure in cancer care. It involves the removal of one or more lymph nodes to determine whether cancer has spread beyond the primary tumor site. This procedure not only helps in accurate cancer staging but also plays a vital role in planning the most effective treatment.
Lymph nodes act as filters in the body’s immune system. When cancer begins to spread, it often travels first to nearby lymph nodes. By removing and examining these nodes under a microscope, doctors can assess how far the disease has progressed and whether additional treatments like chemotherapy, radiation, or immunotherapy are needed.
Lymph node dissection is commonly performed for cancers such as:
Depending on the cancer type and location, either a sentinel lymph node biopsy (removing the first few lymph nodes where cancer is likely to spread) or a complete lymph node dissection (removing a group of lymph nodes) may be recommended.
Benefits of Lymph Node Dissection:
Determines if cancer has spread
Helps guide post-surgical treatment decisions
May reduce the risk of recurrence
Supports accurate cancer staging
Surgical expertise and compassionate patient care to ensure the best possible outcome.
Surgical Stats That Speak for Themselves
Lymph node dissection is more than just a surgical step—it’s a powerful tool in understanding and fighting cancer with precision.
Before surgery, the doctor conducts imaging tests (like ultrasound, CT scan, or MRI) and reviews the cancer diagnosis to decide which lymph nodes need removal. Blood tests and anesthesia clearance are also done.
The surgeon carefully removes either the sentinel lymph nodes (first nodes where cancer may spread) or a group of lymph nodes in the region. Care is taken to avoid damaging surrounding nerves and blood vessels.
The patient is taken to the operating room and given general anesthesia to ensure they are completely asleep and pain-free throughout the procedure.
The removed lymph nodes are sent to a pathology lab, where a specialist examines them under a microscope to check for the presence and extent of cancer cell spread.
A precise incision is made near the area where the lymph nodes are located—commonly in the neck, underarm (axilla), groin, or pelvis—depending on the cancer type and location.
The surgical site is closed with stitches or staples, and a drain may be placed to remove excess fluid. The patient is then monitored during recovery, and post-operative care instructions are given to support healing.
