Most moles are benign and harmless. However, touching a mole, especially if it's already irritated or inflamed, can potentially cause further problems. While most moles won't lead to cancer, scratching or picking at them is not advisable.
Understanding Moles
Moles, also known as nevi, are common skin growths. They're typically harmless, but some can change, grow, or become cancerous. Regular skin checks are crucial to detect any concerning changes. [Source: Reference 1, "While some moles can grow, change or become cancerous – and it's important to have regular skin checks – most are benign and harmless."]
The reason why some moles turn cancerous while most don't is not fully understood, but inflammation plays a significant role. [Source: Reference 2, "Why some moles turn cancerous while the vast majority do not isn't fully understood. Summary. Scientists are learning that inflammation can play..."]
Touching a mole that's already irritated, perhaps from an ingrown hair, can cause redness, pain, and further inflammation. [Source: Reference 3, "...can lead to irritation and inflammation around the mole. This can cause redness and pain at the slightest touch."]
Even benign moles can change in appearance over time; they might get darker or lose color. [Source: Reference 8, "...mole that you've had for a while and feels soft and sometimes wobbly to touch. These benign moles can lose colour or get darker with age and should be..."]
Should You Touch a Mole?
While touching a typical, healthy mole poses no significant direct harm, it's generally best to avoid unnecessary contact. This is particularly true if the mole is already irritated or inflamed.
- Don't pick or scratch: This can introduce infection or cause further irritation.
- Observe regularly: Check your moles regularly for any changes in size, shape, color, or texture.
- Consult a dermatologist: If you have any concerns about a mole, consult a dermatologist for professional evaluation.
Touching moles on other animals (like moles the animal) should be avoided to prevent potential health hazards. [Source: Reference 5, "Homeowners should avoid touching moles or any animals that have had recent contact with the pests to avoid health hazards."]
Conclusion
The simple answer is that while touching a mole isn't inherently dangerous for most people, it's best to avoid it unless necessary for medical examination.
