Skin Spots: When to Worry About Moles and Growths

Could you please clarify your question regarding different doctors?

Hello, recently I visited a dermatologist regarding a black spot on my chest, which the doctor identified as a mole.
The doctor mentioned that its shape, size, and color appeared normal, so I should just monitor it for now.
However, today while showering, I noticed a small spot near my nipple that feels different.
After researching online, it seems it could be either a mole or a granuloma.
Although it's small, its color is not pure black; it has a slight coffee and reddish tint.
Is that possible? Additionally, I would like to ask if moles indicate any internal issues with the body.
I initially thought that only areas exposed to sunlight would develop moles, but the dermatologist said that's not necessarily the case.
Most people have moles, and their quantity is often more than one might expect.
My photo may not be very clear; it's the one in the upper right corner.
I would appreciate it if you could take a look.
Thank you (the photo can be viewed at this link: https://ibb.co/4fjxZHk).

Hello, based on the appearance in the picture, it does resemble a mole.
It is normal for moles to have slight color variations, such as a reddish tint.
Typically, moles are more likely to occur in areas exposed to sunlight, but this is not absolute; they can also appear on the chest.
It is advisable not to pick at the mole and to continue monitoring it.
If there are no significant changes, there is usually no need for concern.
However, if you notice persistent changes, such as an increase in size or a change in color, you should seek medical attention, and consider a biopsy.
Thank you for your question.

When it comes to understanding skin spots, particularly moles and growths, it is essential to approach the topic with a combination of awareness and caution. Your recent experience with a black spot on your chest, which was evaluated by a dermatologist and deemed normal, is a reassuring sign. However, the discovery of a new spot near your nipple that appears slightly different in color raises valid concerns.

Firstly, it is important to understand that moles (or nevi) are common skin growths that can vary in size, shape, and color. Most people have multiple moles, and they can appear anywhere on the body. While many moles are benign, certain characteristics can indicate a need for further evaluation. The ABCDE rule is a helpful guideline for assessing moles:
- Asymmetry: If one half of the mole does not match the other.

- 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 6mm (about the size of a pencil eraser) should be examined.

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

In your case, the new spot's color being a mix of brown and red could be indicative of a few possibilities, including a benign growth like a seborrheic keratosis or a new mole. However, it is crucial to monitor any changes in this spot over time. If it begins to evolve in any of the ways described above, it would be wise to consult your dermatologist for a more thorough examination.

Regarding your concern about moles indicating internal health issues, it is a common misconception. While certain skin conditions can be associated with systemic diseases, most moles are simply a result of genetic factors and sun exposure. The presence of moles does not inherently signify an underlying health problem. However, excessive sun exposure can lead to changes in existing moles or the development of new ones, which is why sun protection is crucial.

If you have a history of significant sun exposure, it is advisable to practice sun safety measures, such as using broad-spectrum sunscreen with an SPF of 30 or higher, wearing protective clothing, and avoiding tanning beds. Regular skin checks, either self-examinations or professional evaluations, can help catch any concerning changes early.

In summary, while your initial assessment by a dermatologist is reassuring, it is essential to remain vigilant about any new or changing spots on your skin. Keep an eye on the new spot near your nipple, and if you notice any changes or have concerns, do not hesitate to seek further medical advice. Regular skin checks and sun protection are key components of maintaining skin health and preventing potential issues in the future.
