Moles on Your Palm: What You Need to Know

Mole on the palm?

Hello doctor, I apologize for my previous question.
I would like to ask about a mole located near the base of my thumb on the palm of my hand.
Many people say that having moles on the palm is not a good sign.
It has been about a week since I noticed it, and its diameter is approximately 0.1 to 0.15 centimeters.
I came across the ABCDE method for mole assessment online; should I be particularly concerned if it meets any of those criteria?

I didn't delete it.
In principle, the more criteria that are met, the greater the likelihood of pathology, but ultimately, a pathological biopsy is essential.

When it comes to understanding moles on your palm, particularly in the area near the base of your thumb, it's important to approach the situation with both caution and knowledge. Moles, or nevi, are common skin growths that can appear anywhere on the body, including the palms. While many moles are benign, certain characteristics can indicate a need for further evaluation.

The ABCDE rule is a widely recognized guideline for assessing moles and identifying potential signs of melanoma, a serious form of skin cancer. The ABCDE acronym stands for:
- 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 examined.

- Color: A mole that has multiple colors or an uneven distribution of color can be a warning sign.

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

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

In your case, the mole you described is relatively small (0.1-0.15 cm), which is generally a good sign. However, it’s essential to consider the other characteristics as well. If the mole is asymmetrical, has irregular borders, displays multiple colors, or has changed in any way since you first noticed it, you should definitely seek medical advice.

It's also worth noting that cultural beliefs about moles can vary widely. Some people may associate moles on the palms with bad luck or other superstitions, but from a medical standpoint, the focus should be on the physical characteristics of the mole itself rather than any cultural interpretations.

If you have any concerns about the mole, especially if it meets any of the ABCDE criteria, it’s advisable to consult a dermatologist. They can perform a thorough examination and, if necessary, a biopsy to determine whether the mole is benign or requires further treatment.

In addition to monitoring the mole, it’s essential to practice good skin care and sun protection. While the palms are less exposed to sunlight than other areas of the body, protecting your skin from UV rays can help reduce the risk of developing skin cancer in general.

In summary, while the presence of a mole on your palm may not inherently indicate a problem, it’s crucial to monitor its characteristics closely. If you notice any changes or if it raises any concerns based on the ABCDE criteria, don’t hesitate to seek professional medical advice. Early detection is key in managing skin health effectively.

It is important to observe closely, but not every mole necessarily indicates a problem. Each lesion should be monitored and discussed separately; having a higher number of moles does not automatically mean a higher risk. If any lesion suddenly shows significant changes, it is adv...
