- Usually painless and slow-growing
⚠️ Causes that need medical attention

- Rapidly growing lump
- Associated symptoms: fever, night sweats, unexplained weight loss, pain
Possible causes can include:
- Infection that needs antibiotics
- Thyroid or salivary gland issues

🩺 What to do
- Monitor the lump for changes in size, pain, or texture
- See a doctor if:
