Moles: When to Worry About Skin Changes - Dermatology

More Info

Understanding moles and skin changes is crucial for maintaining skin health and preventing potential skin cancers, including melanoma. Your concerns about moles, especially given your history of removing one as a child, are valid. Here’s a comprehensive overview addressing your questions and providing additional insights into skin health.

1. Asymmetry and Irregular Borders: When evaluating moles, asymmetry and irregular borders can be concerning signs. The ABCDE rule is a helpful guideline for identifying potentially problematic moles:
- Asymmetry: One half of the mole does not match the other.

- Border: Edges are irregular, ragged, or blurred.

- Color: The color is not uniform and may include shades of brown, black, or even red, white, or blue.

- Diameter: Moles larger than 6mm (about the size of a pencil eraser) should be examined.

- Evolving: Any change in size, shape, color, or elevation, or any new symptom such as bleeding, itching, or crusting.

If your mole is asymmetrical and has irregular borders but feels smooth, it does not automatically mean it is cancerous. However, it is essential to have it evaluated by a dermatologist, especially if there are changes over time.

2. Removing Moles and Cancer Risk: The act of removing a mole does not inherently increase the risk of cancer. However, if a mole is removed without proper medical evaluation, and it turns out to be atypical or cancerous, it could lead to a delay in diagnosis and treatment. It’s crucial to have moles assessed by a healthcare professional before removal. If a mole is deemed suspicious, a dermatologist may perform a biopsy to determine if it is benign or malignant.

3. ABCDE Symptoms and Melanoma: Not all moles that exhibit one or more of the ABCDE characteristics are melanoma. These characteristics are warning signs, but they are not definitive indicators of cancer. A thorough examination by a dermatologist is necessary to make an accurate diagnosis. They may use dermatoscopy, a specialized tool that allows for a closer examination of the skin, to assess the mole more effectively.

In addition to these points, it’s essential to practice sun safety, as UV exposure is a significant risk factor for skin cancer. Regularly applying sunscreen, wearing protective clothing, and avoiding tanning beds can help reduce your risk. Regular skin checks, both self-examinations and professional evaluations, are vital for early detection of any changes.

If you notice any changes in your moles or new symptoms, it’s best to consult a dermatologist promptly. They can provide personalized advice and treatment options based on your specific situation. Remember, early detection is key in managing skin health effectively.
