Moles on the soles of the feet and moles on the fingers?

I would like to ask Dr.
Chen two questions: 1.
I have discovered a 0.3mm brown mole on the sole of my foot in the past six months.
It is symmetrical on both sides, but recently a small brown spot has appeared in front of it.
Should I go to the clinic to check if it is melanoma? 2.
My daughter is 7 years old and has a 0.2mm black mole on the third segment (proximal phalanx) of her right middle finger.
Recently, I noticed that the edges have become irregular and it is growing larger.
Should we go to the clinic to check if it is melanoma? Thank you!

More Info

When it comes to moles on your feet and fingers, it's essential to approach the situation with caution, especially if you notice any changes in size, shape, or color. Moles, or nevi, are common skin growths that can appear anywhere on the body, including the feet and fingers. While most moles are benign, certain characteristics can indicate a higher risk of melanoma, a serious form of skin cancer.

1. Your Mole on the Foot
You mentioned discovering a 0.3mm brown mole on the bottom of your foot that appears symmetrical, along with a new smaller brown mole nearby. The fact that the original mole is symmetrical and relatively small is a positive sign, as asymmetry, irregular borders, and larger size are often red flags for melanoma. However, the appearance of a new mole warrants attention.
The ABCDE rule is a helpful guideline for assessing moles:
- Asymmetry: One half does not match the other.

- Border: Irregular, scalloped, or poorly defined edges.

- Color: A variety of colors (brown, black, tan, red, white, or blue).

- Diameter: Larger than 6mm (about the size of a pencil eraser).

- Evolving: A mole that changes in size, shape, or color.

Since you have a new mole and are concerned about the potential for melanoma, it is advisable to consult a dermatologist. They can perform a thorough examination and, if necessary, a biopsy to determine whether the mole is benign or malignant.

2. Your Daughter's Mole
Regarding your daughter's mole on her right middle finger, which has a diameter of 0.2mm and is showing irregular borders and growth, this is particularly concerning. Children can develop moles, but any changes in size, shape, or color should be evaluated by a healthcare professional. The irregularity in the border and the increase in size are significant factors that warrant further investigation.

In children, melanoma is rare but can occur, and early detection is crucial for successful treatment. Given the characteristics you described, it would be prudent to have her evaluated by a dermatologist as soon as possible. They can assess the mole and determine if a biopsy is necessary.

Conclusion
In summary, while not all moles are harmful, changes in existing moles or the appearance of new ones should not be ignored. It is always better to err on the side of caution when it comes to skin changes, especially in areas like the feet and fingers, where visibility and monitoring can be more challenging. Consulting with a dermatologist will provide you with peace of mind and ensure that any potential issues are addressed promptly. Regular skin checks and awareness of changes in your skin are essential components of skin health, and early intervention can make a significant difference in outcomes if any issues arise.
