A mole, also known medically as a nevus, is a common skin growth formed when melanocytes, the cells responsible for producing skin pigment, grow in clusters instead of spreading evenly throughout the skin. Most individuals develop between 10 and 40 moles by adulthood, and while generally harmless, they can appear anywhere on the body. Picking at a mole is a common action, yet it is generally not advised due to potential consequences.
Immediate Physical Reactions
Picking a mole causes immediate physical responses. Bleeding is common, as trauma disrupts small blood vessels, creating an open wound or abrasion on the skin’s surface.
Alongside bleeding, individuals often experience pain or tenderness at the site of the picked mole. This sensation arises from the stimulation of nerve endings present in the skin. The extent of bleeding and pain can vary depending on the depth and force of the picking, as well as the mole’s size and elevation.
Potential Complications
Picking a mole can lead to several complications. One risk is infection, as breaking the skin’s barrier provides an entry point for bacteria. Signs of infection include worsening redness, swelling, increased pain, warmth, and pus. Proper wound care, such as cleaning the area with mild soap and water, helps prevent bacterial entry.
The body’s response to trauma involves inflammation, causing swelling and redness around the injured site. This process is part of healing but can cause sensitivity and discomfort. Even without bacterial infection, physical irritation from picking can trigger this immune response.
Scarring is another consequence as the skin heals after trauma. The resulting mark can be more noticeable than the original mole, potentially including hyperpigmentation (darkening), hypopigmentation (lightening), or raised scars like keloids or hypertrophic scars. Keloids are firm, rubbery lesions that grow beyond the original wound boundaries, while hypertrophic scars are raised but remain within the confines of the original injury. The type and visibility of the scar depend on individual healing factors and the extent of the damage.
Challenges for Monitoring
Moles are frequently monitored for any changes that could signal the development of skin cancer, particularly melanoma. Picking a mole can significantly alter its appearance, making routine self-examinations and professional dermatological assessments more difficult. The trauma can cause bleeding, scabbing, or inflammation, which can obscure the mole’s original characteristics.
These alterations interfere with the effective application of the ABCDEs of melanoma detection: Asymmetry, Border irregularity, Color variation, Diameter, and Evolving changes. For example, a picked mole might appear asymmetrical or have an irregular border due to scabbing or healing, even if it was previously benign. Similarly, inflammation or a new scab can introduce color variation or increase the perceived diameter, masking true suspicious changes. An undisturbed mole allows for a clearer and more accurate assessment of these indicators over time.
When to Consult a Doctor
Consult a doctor if certain signs or symptoms appear after picking a mole. Seek medical attention for signs of infection, including worsening redness, increased swelling, warmth, persistent pain, or pus. Continued bleeding that doesn’t stop with gentle pressure, or persistent pain, also warrants professional evaluation.
Consult a doctor if the mole does not heal properly or quickly, or if any new or changing mole is observed, regardless of whether it was picked. This includes changes in size, shape, color, or texture. If the mole already displayed suspicious characteristics before it was picked, such as asymmetry, irregular borders, varied color, or a diameter larger than 6 millimeters, seek prompt medical consultation. Avoid picking moles and seek professional advice for any concerns regarding skin growths.
