Noticing a lump on your hand can be worrying, but many causes are benign (non-cancerous). Still, it’s important to understand what it might be and when to seek medical advice. ✋🩺
Common Causes of Hand Lumps
1. Ganglion cyst
- The most common hand lump.
- Filled with jelly-like fluid and often appears on the wrist or fingers.
- Usually harmless but may cause discomfort or limit movement.
2. Lipoma
- Soft, movable lump made of fat tissue.
- Typically painless and slow-growing.
3. Dupuytren’s contracture
- Thick lumps or cords in the palm.
- Can cause fingers to gradually curl inward.
4. Giant cell tumor of the tendon sheath
- Firm lump near a tendon.
- Usually slow-growing but may need medical evaluation.
5. Rheumatoid nodules
- Occur in people with Rheumatoid arthritis.
Warning Signs to See a Doctor
You should seek medical advice if the lump:
- Grows quickly
- Causes pain, numbness, or weakness
- Is hard, fixed, or irregular
- Appears after an injury
- Doesn’t go away after several weeks
A doctor may examine the lump and sometimes use ultrasound, MRI, or biopsy to determine what it is.
