More Info

Moles, also known as nevi, are common skin growths that can change in appearance over time. It is not unusual for moles to change in size, shape, or color as a person ages. However, understanding the nature of these changes is crucial to distinguishing between benign changes and potential signs of skin cancer.

Do Moles Change with Age?
Yes, moles can change as we age. Many people have moles that appear during childhood or adolescence, and these moles may grow or change in color as a person matures. Some moles may become larger, darker, or even develop hair. These changes are often benign and part of the natural aging process. However, it is essential to monitor any changes closely.

Myths and Facts About Skin Spots
1. Myth: All changes in moles indicate cancer.
- Fact: While changes in moles can be a sign of skin cancer, not all changes are malignant. Many benign moles can change in size and color without indicating cancer. It is essential to look for specific warning signs, such as asymmetry, irregular borders, multiple colors, a diameter larger than a pencil eraser, or any changes in elevation or texture.

2. Myth: New moles after age 30 are always cancerous.
- Fact: It is common for new moles to appear in adulthood, and while some may be atypical, many are benign. However, any new mole or change in an existing mole after the age of 30 should be evaluated by a dermatologist, especially if there are any concerning features.

3. Myth: Moles cannot be removed unless they are cancerous.
- Fact: Moles can be removed for cosmetic reasons or if they are bothersome. If a mole is suspected to be cancerous, a dermatologist may recommend a biopsy to determine its nature.

Your Specific Case
In your situation, you mentioned a mole on your hand that has grown from less than 0.1 cm to 0.1 cm in size and is a light brown color without any other symptoms. While this change may not be alarming, it is essential to monitor it closely. Here are some steps you can take:
- Self-Examination: Regularly check your mole and other moles on your body for any changes in size, shape, color, or texture. If you notice any significant changes, it is advisable to consult a dermatologist.

- Dermatological Evaluation: Given that the mole has changed in size, it would be prudent to have it evaluated by a dermatologist. They can perform a thorough examination and may recommend a biopsy if there are any concerns.

- Surgical Removal: If the mole is determined to be benign but bothersome, you can discuss the option of removal with your dermatologist. Surgical removal is a common procedure and can provide peace of mind.

Conclusion
In summary, moles can indeed change with age, and while many changes are benign, it is crucial to remain vigilant. The myth that all new moles after age 30 are cancerous is not true, but any new or changing mole should be evaluated by a healthcare professional. Regular skin checks and awareness of the ABCDEs of moles (Asymmetry, Border, Color, Diameter, Evolving) can help you stay proactive about your skin health. Always consult with a dermatologist for personalized advice and treatment options.
