Swollen Lymph Nodes: Causes, Pain, and When to See a Doctor

While swollen or inflamed lymph nodes can be a sign of cancer, it's important to note that they are often caused by other, less serious conditions such as infections or injuries. Painful lymph nodes are not necessarily indicative of cancer. In fact, cancerous lymph nodes often don't cause pain. If you are concerned about a swollen or painful lymph node, it's best to see a doctor for proper evaluation.
