Raised Moles: Dermatological Insights and Concerns - Dermatology

More Info

---

When it comes to raised moles, or nevi, understanding their characteristics and potential concerns is crucial for maintaining skin health. Moles are common skin growths that can vary in size, shape, and color. They are usually benign, but certain changes in their appearance can warrant further investigation.

In your case, you have described two moles: one located on the scalp and another on the cheek. The mole on your scalp has been present for approximately seven to eight years and was initially thought to be a scab from a previous injury. The second mole on your cheek has been there for about ten years and has shown slight growth over time, with a characteristic of releasing oil when pressed.


Characteristics of Moles
1. Shape and Texture: Moles can be flat or raised, smooth or rough. The fact that your scalp mole is soft to the touch is generally a good sign, as benign moles often have a soft texture. However, any sudden changes in texture or shape should be monitored.

2. Color: Moles can range from light brown to black. A uniform color is typically a sign of a benign mole, while variations in color can be a cause for concern.

3. Size: Moles larger than 6mm (about the size of a pencil eraser) should be evaluated by a dermatologist. If your moles have grown significantly or have changed in size, this could indicate a need for further assessment.

4. Symmetry: Benign moles are usually symmetrical. If you were to draw a line through the middle of the mole, both halves would look the same. Asymmetry can be a warning sign.

5. Border: The edges of a benign mole are typically smooth and even. Irregular or jagged edges can be a cause for concern.


When to Seek Medical Advice
Given your description, it’s important to keep an eye on these moles. Here are some signs that should prompt you to consult a dermatologist:
- Changes in Size or Shape: If either mole begins to grow, change shape, or develop irregular borders, it is advisable to seek medical advice.

- Color Changes: Any darkening or uneven coloration should be evaluated.

- Bleeding or Itching: If the mole starts to bleed, itch, or become painful, this could indicate a problem.

- New Symptoms: The appearance of new moles or changes in existing ones should be assessed.


Dermatological Evaluation
A dermatologist can perform a thorough examination of your moles, often using a dermatoscope, which allows for a more detailed view of the skin. If there are concerns, they may recommend a biopsy to rule out any malignancy.

Conclusion
While many moles are harmless, it’s essential to be vigilant about any changes. Regular skin checks, either self-examinations or professional evaluations, can help catch potential issues early. If you have any doubts or notice changes in your moles, don’t hesitate to reach out to a healthcare professional for advice. Early detection is key in managing skin health effectively.
