New Skin Bumps: When to See a Doctor

Finding a new bump on your skin can be concerning, but not all bumps are cause for alarm. Skin changes are common, and most bumps are harmless. However, it’s important to know when a new bump could be a sign of something more serious, warranting a visit to the doctor.

Common Causes of Skin Bumps

Before panicking, it’s useful to recognize that many new bumps are benign. Common types include:

• Cysts: Fluid-filled sacs that are usually harmless but can become infected
• Lipomas: Soft, fatty lumps that grow under the skin and are non-cancerous
• Skin Tags: Small, flesh-colored growths often found in areas of friction, like the neck or armpits
• Moles: Pigmented growths that are usually harmless but should be monitored for changes
• Acne: Pimples or blackheads that are common during hormonal changes or skin irritation

While these conditions are generally not a cause for concern, there are times when new skin bumps may indicate a more serious issue.

When to See a Doctor

There are several signs that it’s time to see a doctor about your new skin bump.

• Changes in size, shape or color. If a bump starts to grow rapidly, changes color or takes on an irregular shape, it could indicate a more serious skin condition like skin cancer. Moles, in particular, should be monitored for any signs of asymmetry, irregular borders, multiple colors or a diameter larger than a pencil eraser.
• Pain, itching or bleeding. Bumps that are painful, constantly itchy or start bleeding without obvious trauma could be a sign of an underlying infection or skin condition that requires treatment.
• Hard or firm texture. A hard, immovable bump under the skin could be a sign of an issue deeper in the skin. These should be evaluated by a doctor, especially if they are persistent or growing.
• Bumps that don’t heal. If you notice a bump that hasn’t healed after several weeks or continues to grow, this could be a sign of a skin infection, or in some cases, skin cancer.
