Moles: When to Worry and When to Observe

Could you please provide more details about the issue with moles?

Hello Doctor, I often come across articles online that assert definitively that the palms of the hands and soles of the feet lack melanocytes, so any mole in those areas must be removed.
I have a stable mole on my palm, and my wife noticed a tiny new mole on both her hands and feet during her pregnancy, and none of them have changed.
Regarding moles, is it sufficient to just monitor them for any unusual changes? It seems impractical to remove or laser every single one we see.
Additionally, at what age do moles typically stop developing? Many online sources claim that moles shouldn't appear after middle age, and honestly, I find these articles quite concerning.
Sometimes, while just relaxing online, I come across alarming warnings that make me anxious.
I feel it's better to consult a doctor for accurate information.
Thank you, Doctor, and I wish you well.

It is recommended to monitor yourself, and if there are no unusual changes, there is no need to worry.
Additionally, the development of moles does not follow a specific timeline.

More Info

When it comes to moles, or nevi, it's essential to understand their nature and when they might warrant concern. Moles are common skin growths that can appear anywhere on the body, including the palms and soles, although they are less common in these areas due to the lower number of melanocytes (the cells that produce pigment). The presence of a mole in these areas does not automatically indicate a problem, especially if it has remained unchanged over time.

When to Worry About Moles
The general rule of thumb for monitoring moles is the "ABCDE" criteria, which can help you identify potential warning signs of melanoma, a serious form of skin cancer:
- Asymmetry: If you draw a line through the mole, and the two halves do not match, it may be a cause for concern.

- Border: Moles with irregular, scalloped, or poorly defined edges should be evaluated.

- Color: A mole that has multiple colors (brown, black, tan, red, white, or blue) is more suspicious than a uniformly colored mole.

- Diameter: Moles larger than 6mm (about the size of a pencil eraser) are more likely to be problematic.

- Evolving: If a mole changes in size, shape, color, or elevation, or if it begins to itch or bleed, it should be examined by a healthcare professional.

If your mole on your palm is stable and does not exhibit any of these characteristics, it is generally safe to observe it rather than rush to remove it. The same goes for the small mole your wife noticed during her pregnancy; hormonal changes can sometimes lead to the development of new moles, but if they remain unchanged, they are usually not a cause for alarm.

The Growth of Moles Over Time
Moles can develop at any age, but they are most commonly seen in children and young adults. It is typical for individuals to develop new moles until their mid-30s. After this age, the formation of new moles tends to slow down, and existing moles may change in appearance. However, it is not uncommon for some people to develop new moles even into middle age or later.

Managing Anxiety About Moles
It is understandable to feel anxious after reading alarming articles online about moles and skin cancer. The internet can be a source of misinformation and can lead to unnecessary worry. It is crucial to remember that not all moles are dangerous, and many people have benign moles that do not require treatment. Regular self-examinations and awareness of any changes in your skin can help you stay informed about your health without becoming overly anxious.

If you have concerns about a specific mole or notice any changes, it is always best to consult with a dermatologist. They can provide a thorough examination and, if necessary, perform a biopsy to rule out any malignancy. Regular check-ups with a dermatologist can also help you feel more secure about your skin health.

Conclusion
In summary, while it is essential to monitor moles for any changes, not every new or existing mole requires removal, especially if it remains stable and does not exhibit concerning characteristics. Regular self-examinations and consultations with a healthcare professional can help you manage any concerns effectively. Remember, knowledge is power, and understanding your body can help alleviate unnecessary fears.
