When to worry about neck lumps and what to do about them

Swollen lymph nodes in the neck are often harmless signs of an illness, but they can occasionally signal something more serious. Here’s what you need to know:

**What Are Lymph Nodes?**
Lymph nodes are small, bean-shaped structures that filter lymph fluid, removing germs, waste, and cancer cells. Swollen nodes usually indicate the immune system is fighting off an infection.

**When to Worry:**
Swollen lymph nodes may require medical attention if:
– Swelling lasts longer than two weeks.
– You experience fever, weight loss, or unexplained pain.
– A node grows quickly, feels hard, or spreads to multiple areas.

**What Doctors Do:**
To investigate swollen lymph nodes, doctors perform a physical exam, review your medical history, and may order imaging tests or a biopsy.

**Treatment Options:**
Treatment depends on the cause:
– **Infections:** Antibiotics or over-the-counter pain relief.
– **Inflammatory diseases:** Immune-suppressing medications.
– **Cancer:** Chemotherapy, radiation, or surgery.

**Conclusion:**
Swollen lymph nodes are usually harmless, but persistent or concerning symptoms warrant a doctor’s visit to ensure timely care.
