Ganglion Cyst: That Lump on Your Wrist Explained (No Drama)
That image shows a classic ganglion cyst — and despite how it looks:
It’s usually harmless.
Let’s break it down properly.
1. What a Ganglion Cyst Actually Is
6
- A fluid-filled sac
- Comes from a joint or tendon sheath
- Most common on the back of the wrist
Inside = thick, jelly-like fluid (not pus, not tumor).
2. Why It Appears
6
Exact cause isn’t always clear, but linked to:
- Repetitive wrist movement
- Joint irritation
- Minor trauma
Think: pressure buildup → fluid pushes out → lump forms
3. Symptoms (or No Symptoms at All)
7
- Visible lump
- May feel soft or firm
- Can change size
- Sometimes causes:
- Mild pain
- Tingling (if pressing on a nerve)
Many people have zero pain.
4. Is It Dangerous?
No — it’s benign (non-cancerous).
It does NOT:
- Turn into cancer
- Spread
- Infect others
Main issue = discomfort or appearance.
5. Do You Need Treatment?
5
Only if:
- It hurts
- Limits movement
- Keeps growing
Options:
- Do nothing (many disappear on their own)
- Drain fluid (may come back)
- Surgery (for persistent cases)
6. What NOT To Do
- ❌ Don’t smash it (old myth, bad idea)
- ❌ Don’t self-drain at home
That can cause injury or infection.
Final Take
Lump on wrist = scary looking, but usually harmless
