Understanding foot moles, or nevi, can be a complex issue that often requires careful evaluation by a dermatologist. Your experience with different dermatologists highlights the variability in medical opinions, which is not uncommon in dermatology, especially when it comes to skin lesions like moles.
Moles are generally benign growths of melanocytes, the cells responsible for producing pigment in the skin. Most moles are harmless, but changes in their appearance, such as size, shape, color, or texture, can be concerning and warrant further investigation. The fact that your mole has been stable for several years is a positive sign, as stability is often associated with benignity. However, it is essential to remain vigilant and monitor any changes.

The dermatologist you consulted who scraped the mole and assessed it as benign likely performed a simple test known as a "shave biopsy." This procedure can help determine if there are any atypical cells present. If the mole has not changed over time, the risk of it being malignant (cancerous) is generally low. However, it is crucial to understand that while the risk may be low, it is not zero. Regular monitoring and self-examination are key components of skin health.

Regarding the potential for a mole to become cancerous, it is true that the risk is similar to that of normal skin. However, certain types of moles, particularly atypical moles or dysplastic nevi, may carry a higher risk of developing into melanoma, a serious form of skin cancer. The ABCDE rule (Asymmetry, Border irregularity, Color variation, Diameter larger than 6mm, and Evolving) is a helpful guide for identifying moles that may require further evaluation.

The discussion about laser removal versus surgical excision is also significant. Laser treatments can be effective for cosmetic purposes but may not remove the mole entirely, especially if there are deeper melanocytes involved. Surgical excision, on the other hand, allows for complete removal and can provide a definitive diagnosis through histopathological examination. If there is any suspicion of melanoma, excision is often the preferred method to ensure complete removal and to assess the mole's characteristics accurately.

Your experience with the differing opinions of dermatologists underscores the importance of seeking a second opinion, especially when it comes to skin lesions. If you feel uncertain about the advice given, it is entirely reasonable to consult another specialist for further evaluation.
In conclusion, while your mole appears stable and benign based on the assessments you've received, ongoing vigilance is essential. Regular self-examinations and consultations with dermatologists can help ensure that any changes are caught early. If you notice any new symptoms or changes in your mole, do not hesitate to seek further medical advice. Remember, your health and peace of mind are paramount, and being proactive about your skin health is a wise approach.
