Unusual Moles: When to Seek Dermatological Advice

Regarding moles on the body?

I would like to ask: I have a mole located just below my chest that is approximately 0.3 centimeters in diameter.
The color is not very uniform, with parts being brown and others black, and it looks different from my other moles.
Additionally, since it is positioned right at the edge of my bra, it often gets rubbed by the bra.
Is this a concern? Should I consider having it removed? Also, is the uneven color of the mole a sign of something abnormal? Thank you.

In addition to monitoring the color of moles, it is important to observe their size, whether their shape is symmetrical, and if there are any irregular protrusions.
It is advisable to first seek a diagnosis from a dermatologist.
If the mole is not malignant and you can perform regular self-examinations monthly, with a follow-up appointment with the doctor every three months, there may be no need for immediate surgical intervention.
However, if you find yourself constantly preoccupied and distressed about it, it may be worth considering surgical removal for peace of mind.

More Info

When it comes to unusual moles or skin lesions, it is essential to be vigilant and proactive about any changes or characteristics that may indicate a potential issue. In your case, you have described a mole located on your chest that is approximately 0.3 cm in diameter, with uneven coloration—some parts being brown and others black. Additionally, you mentioned that this mole is situated at the edge of your bra, which leads to frequent friction.
Firstly, it is important to understand that moles, or nevi, can vary widely in appearance. Most moles are benign and do not pose any health risks. However, certain characteristics can raise concerns, particularly when it comes to the risk of melanoma, a serious form of skin cancer. The ABCDE rule is a helpful guideline for assessing moles:
- Asymmetry: If you draw a line through the mole, the two halves do not match.

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

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

- Diameter: Moles larger than 6 mm (about the size of a pencil eraser) are more concerning, although smaller moles can also be problematic.

- Evolving: Any change in size, shape, color, or elevation, or any new symptom such as bleeding, itching, or crusting.

Based on your description, the uneven coloration of your mole is a point of concern, as it does not conform to the typical appearance of benign moles. The fact that it is located in an area subject to friction from your bra could potentially lead to irritation or changes in the mole's appearance, which is another reason to monitor it closely.

Given these factors, it is advisable to seek dermatological advice. A dermatologist can perform a thorough examination and may recommend a biopsy if they believe the mole warrants further investigation. This is particularly important if the mole exhibits any of the ABCDE characteristics mentioned above.
In terms of whether you should have it removed, that decision is best made in consultation with a healthcare professional. If the mole is determined to be benign but is causing discomfort due to friction, removal may be a reasonable option for comfort's sake. If there are any signs of malignancy, prompt removal and further treatment may be necessary.

In summary, while many moles are harmless, the characteristics you've described warrant a professional evaluation. It is always better to err on the side of caution when it comes to skin changes. Regular skin checks and being aware of any new or changing moles are crucial steps in maintaining skin health. If you have any further questions or concerns, do not hesitate to reach out to a dermatologist for personalized advice and care.
