Lymph node dissection: when it is needed and what to expect
Article image
A plain explanation of the role lymph nodes play in cancer surgery, when dissection is part of the plan, and what follow-up looks like.
Why do lymph nodes matter?
Lymph nodes are part of the immune system, and they can also be a route of spread for some cancers. Assessing them helps with staging and directly influences the overall treatment plan.
When is dissection needed?
- Suspicious nodes on exam or imaging
- As part of a protocol for a specific tumour stage
- For diagnostic sampling when nodes are the clearest manifestation of disease
Questions to ask
- Is it primarily diagnostic or therapeutic?
- Which region is targeted (neck/axilla/groin) and why?
- What are the expected risks and how can we reduce them?
Follow-up
Some patients may experience limb swelling (lymphedema), depending on region and extent. Early follow-up, appropriate exercises and wound care instructions reduce risk.
Every case is different: the goal and extent of dissection are decided based on diagnosis, imaging and a clear discussion with the patient.
