When to Worry About Swollen Lymph Nodes With Metastatic Cancer

Lymph nodes can enlarge when immune cells respond to infection, inflammation, or cancer cells. A change may occur near the original tumour or in another drainage area. The feel, location, and timing matter, yet examination alone cannot identify the cause. Your team may compare the node with earlier examinations and review scans or other tests already planned.

Contact your oncology team about any new node or a clear change in one you already know about. Note when you first noticed it, where it is, whether it is growing, and whether you have fever, night sweats, weight loss, skin changes, or recent infection. Do not repeatedly press the area, because this can make it sore and harder to assess.

Seek urgent medical help for trouble breathing or swallowing, sudden swelling of the face or neck, severe pain, confusion, fainting, or a high fever with marked weakness. Contact your cancer team promptly if a node grows quickly, becomes increasingly painful or red, drains, or appears with new symptoms that concern you.

Ask which changes should be reported the same day, whether the node is in a known spread pattern, and which examination or scan could clarify it. You can also ask how infection or treatment effects will be considered and when you should expect the next review.
