the Increase of Moles: Causes, Concerns, and Care

Mole pigmentation

Hello Doctor, in the past two years, I have noticed many new moles appearing on my body, both red and black, especially on my back, waist, and arms.
There is also one in my intimate area, and a few on my face.
Now, if I count them all, there should be more than 20.
Is it normal to have that many moles on the body? I haven't paid much attention to them and don't know how long they have been there.
However, there are three to four moles that are quite noticeable and large.
They feel smooth to the touch, but I have the impression that they have grown larger in recent years.
I usually get very little sun exposure, but my skin tends to easily develop pigmentation.
Additionally, my menstrual cycle has been irregular for nearly a year, and I often stay up late.
Could this have increased melanin production? Or could it be related to genetics? Or perhaps my metabolism is not very good, which could also contribute to this? I am a bit worried that the moles will continue to grow or get larger.
Besides changing my lifestyle, how can I prevent them from continuing to appear and how should I care for them? Also, if I want to remove a mole in the future, how much does it typically cost to remove one? I am only 22 years old and am unsure if it is necessary.
I might consider removing some on my face, but if they keep appearing, having over 20 scattered all over my body is quite a lot.
I am just afraid they will continue to grow.
Would you recommend that I see a dermatologist for a more thorough evaluation?

Dear Patient,
Thank you for reaching out with your concerns regarding the sudden increase in moles on your body. It’s understandable to feel anxious about changes in your skin, especially when it comes to moles, as they can sometimes indicate underlying health issues. Let’s break down your concerns regarding the appearance of new moles, their potential causes, and what steps you can take moving forward.

Firstly, it is not uncommon for individuals to develop new moles throughout their lives, particularly during adolescence and early adulthood. The average adult has between 10 to 40 moles, and it is normal for some people to have more than this. However, the sudden appearance of many new moles, especially if they are changing in size, shape, or color, should be monitored closely.
The factors you mentioned—hormonal changes, skin type, and lifestyle—can indeed contribute to the development of new moles. Hormonal fluctuations, particularly those associated with menstruation, can stimulate melanin production, leading to increased pigmentation in the skin. Additionally, while you mentioned that you rarely sunbathe, UV exposure can still occur through incidental sun exposure, which can also lead to the formation of new moles.
Genetics play a significant role in the number and type of moles a person has. If you have a family history of numerous moles or skin conditions, this could be a contributing factor. Furthermore, your mention of easy pigmentation suggests that your skin may be more reactive to various stimuli, which could include hormonal changes or even stress.

Regarding your concern about the moles becoming larger or changing, it is essential to keep an eye on them. The ABCDE rule is a helpful guideline for monitoring moles:
- Asymmetry: One half of the mole doesn’t match the other.

- Border: Edges are irregular, ragged, or blurred.

- Color: The color is not uniform and may include shades of brown, black, or even red, white, or blue.

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

- Evolving: The mole is changing in size, shape, or color.

If any of your moles exhibit these characteristics, it is advisable to consult a dermatologist for a thorough evaluation. They can perform a skin examination and, if necessary, a biopsy to rule out any serious conditions.

In terms of prevention and care, maintaining a healthy lifestyle can help. This includes:
1. Regular Skin Checks: Monitor your skin for any changes in existing moles or the appearance of new ones.

2. Sun Protection: Even if you don’t sunbathe, using sunscreen daily can help protect your skin from UV damage.

3. Healthy Diet: A balanced diet rich in antioxidants can support skin health.

4. Hydration: Staying well-hydrated can improve skin elasticity and overall appearance.

If you decide to remove any moles, the cost can vary widely based on the method of removal (excision, laser treatment, etc.) and the location of the procedure. It’s best to consult with a dermatologist to discuss your options and get a cost estimate.

At 22 years old, it’s understandable to be concerned about your skin's appearance. If the moles continue to increase or change, seeking professional advice is the best course of action. A dermatologist can provide tailored recommendations based on your specific situation and skin type.

In conclusion, while having numerous moles can be normal, it’s crucial to monitor their characteristics and consult a healthcare professional if you have any concerns. Taking proactive steps in skin care and regular check-ups can help ensure your skin remains healthy.

Best wishes for your health and well-being.
