Skin Lump or Bump: Causes, Types & When to Worry
Skin lumps and bumps are very common and usually harmless. Most are cysts, lipomas, or skin tags that don't require treatment unless they're bothersome. However, new or changing lumps, especially those that are hard, fixed, or growing rapidly, should be evaluated by a healthcare provider to rule out skin cancer or other concerns.
Quick Answer
Warning signs include: hard lumps that don't move, rapid growth, irregular borders, color changes, bleeding or ulceration, and lumps that keep coming back after removal. Any concerning lump should be evaluated by a doctor.
