Step 1: What Are They?
Cherry angiomas are small, benign (non-cancerous) growths on the skin made up of an overgrowth of tiny blood vessels (capillaries). They appear as bright red, round or oval spots and are one of the most common skin growths in adults.
Step 2: What Do They Look Like?
- Color: Bright cherry-red to purple
- Size: 1–5 mm in diameter (some can grow larger)
- Shape: Round or slightly raised dome-shaped bumps
- Texture: Smooth; may be flat or slightly elevated
- Location: Most commonly found on the torso (chest, abdomen, back), but can appear anywhere
Step 3: What Causes Them?
The exact cause is not fully known, but contributing factors include:
- Age — Most common after age 30; prevalence increases with age
- Genetics — They tend to run in families
- Hormonal changes — Pregnancy or hormonal shifts can trigger new ones
- Sun exposure — UV radiation may play a role
- Chemical exposure — Some chemicals (bromides, mustard gas) have been linked to outbreaks
Step 4: Are They Dangerous?
No. Cherry angiomas are almost always harmless. However, you should see a doctor if:
- A spot bleeds frequently
- It changes in shape, color, or size rapidly
- It looks irregular or asymmetric (to rule out melanoma or other conditions)
- You develop many new spots suddenly — this can occasionally signal an internal condition (rare)
