Moles on the Sole: When to Seek Medical Advice

Mole on the sole of the foot?

Hello Doctor: About five months ago, I discovered a mole on the sole of my foot with a diameter of approximately 1 millimeter.
However, there are no other symptoms, and it hasn't been growing larger.
I saw news reports suggesting it could be a precursor to cancer.
What should I do about this? Thank you.

Actually, having moles on the soles of your feet is quite common, while skin cancer in that area is rare.
If you are concerned, you should visit a hospital and see a dermatologist for a biopsy.

When it comes to moles or any skin lesions, especially those that appear on the soles of the feet, it is essential to approach the situation with caution and awareness. The mole you described, which is approximately 1 millimeter in diameter and has not changed in size or exhibited any other symptoms, may not be an immediate cause for concern. However, it is crucial to understand the characteristics of moles and when to seek medical advice.

Moles, or nevi, are common skin growths that can vary in color, size, and shape. Most moles are benign and do not pose any health risks. However, certain changes in a mole can indicate potential issues, including skin cancer, particularly melanoma. The ABCDE rule is a helpful guideline for evaluating moles:
1. Asymmetry: One half of the mole does not match the other half.

2. Border: The edges of the mole are irregular, ragged, or blurred.

3. Color: The mole has varying colors, including shades of brown, black, or even red, white, or blue.

4. Diameter: Moles larger than 6 millimeters (about the size of a pencil eraser) are more concerning, although some melanomas can be smaller.

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

Given that your mole has remained stable for five months and does not exhibit any of the concerning characteristics mentioned above, it may not be a cause for alarm. However, it is always wise to err on the side of caution, especially when it comes to skin changes.
Here are some recommendations for managing your situation:
1. Monitor the Mole: Keep an eye on the mole for any changes in size, shape, color, or symptoms. Take note of any new moles that may appear.

2. Consult a Dermatologist: It is advisable to schedule an appointment with a dermatologist for a professional evaluation. They can perform a thorough examination and may recommend a biopsy if there are any concerns. A dermatologist is trained to identify potential skin cancers and can provide you with peace of mind.

3. Educate Yourself: Familiarize yourself with the signs of skin cancer and the importance of regular skin checks. This knowledge can empower you to take charge of your skin health.

4. Sun Protection: Regardless of the mole's status, practicing sun safety is crucial. Use sunscreen with a high SPF, wear protective clothing, and avoid excessive sun exposure, as UV radiation can contribute to skin cancer risk.

5. Regular Skin Checks: Incorporate regular self-examinations into your routine. This practice can help you catch any changes early and seek medical advice promptly.

In conclusion, while your mole does not currently exhibit alarming characteristics, it is essential to remain vigilant and proactive about your skin health. Consulting a dermatologist will provide you with the best course of action and reassurance regarding your concerns. Remember, early detection is key in managing skin health effectively.

To determine whether a mole has undergone any pathological changes, a biopsy is necessary for a definitive diagnosis. If there are no changes in the short term, it is reasonable to monitor it; however, if there are significant changes, a biopsy should still be considered.
