1. Analysis of the causes of moles
Moles (pigmented nevus) are benign tumors formed by the local accumulation of melanocytes on the skin. The main reasons why there are many moles on the arms include:
| Influencing factors | Specific instructions |
|---|---|
| genetic factors | Family genetic predisposition leads to dense distribution of melanocytes |
| UV exposure | Long-term exposure to sunlight on arms accelerates melanin deposition |
| Hormone changes | Hormone fluctuations during puberty/pregnancy may trigger new moles |
| skin type | Fair skin is more likely to show pigmentation |

| 1 | Skin moles and health | 28.5 | Cancerous nevus, melanoma |
| 2 | Sun protection and skin aging | 19.3 | UV rays, photoaging |
| 3 | Genetic testing of skin characteristics | 12.7 | Genetic risks, skin care |
3. Characteristics of moles that require vigilance (ABCDE rule)
Not all moles require treatment, but medical examination is recommended if:
| Features | normal mole | red flag |
|---|---|---|
| shape | Symmetrical circle | Asymmetrical lobulation |
| edge | Smooth and clear | blurry/jagged |
| Color | uniform brown | Mixed colors |
| diameter | <6mm | rapid increase |
| change | stable | itching/bleeding |
4. Scientific nursing suggestions
1.Sun protection is a priority:Ultraviolet rays are the main cause of the increase in moles. It is recommended to use SPF30+ sunscreen and wear sun-protective clothing.
2.Regular records:Take photos of moles with your mobile phone and compare them every 3 months to observe the changes.
3.Avoid irritation:Do not touch the mole or rub the mole body randomly, as this may induce malignant transformation.
4.Nutritional adjustment:Vitamin C/E can inhibit excessive synthesis of melanin, so supplement foods rich in antioxidants in an appropriate amount.
5. Excerpts from expert opinions
The latest research from the Chinese Society of Dermatology shows that adults have an average of 15-40 moles, of which 35% are located on the upper limbs. The number of moles has a genetic correlation of up to 70%, but a sudden increase in a short period of time requires investigation of ultraviolet exposure or immune system abnormalities.
