Should I Remove a New Mole on My Palm? Dermatologist Insights

New mole on the palm?

Hello Doctor: I am 25 years old and recently noticed a mole approximately 0.1 cm in size located just below and to the side of my right thumb.
I'm not sure when it appeared.
It has a flat surface, regular shape, and even color.
However, I have heard that moles that develop after the age of 20 have a higher chance of causing problems, and since individuals of East Asian descent are more prone to melanoma in areas like the hands and soles of the feet, I would like to ask if this mole should be removed.
If removal is necessary, will it be complicated? (For example, will there be a wound?) Thank you, Doctor, for taking the time to answer my question.

A literal description without actually seeing the lesion cannot confirm the diagnosis.
It is recommended to have a physician evaluate it before providing any advice.
If surgery is needed and the lesion is not large, it should not be too complicated.

More Info

When it comes to moles, especially new ones that appear after the age of 20, it is essential to approach the situation with caution. The mole you described on your palm, measuring approximately 0.1 cm, appears to have a regular shape and uniform color, which are generally positive signs. However, the fact that it is new and located in an area that is prone to skin cancers, such as the palms and soles, warrants further evaluation.

In dermatology, we often use the ABCDE rule to assess moles for potential malignancy:
- Asymmetry: If one half of the mole does not match the other half.

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

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

- Diameter: If the mole is larger than 6mm (about the size of a pencil eraser).

- Evolving: If the mole changes in size, shape, or color over time.

Based on your description, your mole does not seem to exhibit any alarming characteristics according to the ABCDE rule. However, since it is new and you have concerns about it, it is advisable to consult a dermatologist for a professional evaluation. They may perform a dermatoscopic examination, which allows for a more detailed view of the mole's structure and can help determine if a biopsy is necessary.

Regarding the removal of the mole, if the dermatologist deems it necessary, the procedure is typically straightforward. Mole removal can be done through excision (cutting it out) or shave removal (slicing it off at the skin level). Both methods are usually performed under local anesthesia, meaning you will not feel pain during the procedure.
Post-removal, there will be a wound that needs care. The healing process can vary, but generally, it takes a couple of weeks for the skin to heal. You may experience some discomfort, swelling, or redness in the area, but these symptoms typically resolve with proper care. Your dermatologist will provide you with specific aftercare instructions, which may include keeping the area clean, applying ointment, and avoiding sun exposure to prevent scarring.

It is also important to monitor your skin regularly for any new moles or changes in existing moles. If you notice any changes, such as itching, bleeding, or any other unusual symptoms, you should seek medical advice promptly.

In summary, while your mole does not seem to exhibit concerning features, it is wise to have it evaluated by a dermatologist. They can provide you with peace of mind and, if necessary, perform a simple removal procedure. Regular skin checks and awareness of changes in your skin are crucial for early detection of any potential issues.
