Moles are usually harmless clusters of pigmented skin cells. However, when they begin to change in color, size, or shape—or if they start itching or bleeding—they can signal melanoma or other skin cancers. Early detection and treatment are critical for a better outcome.

To identify potentially dangerous moles, dermatologists recommend the ABCDE rule: Asymmetry, Border irregularity, Color variation, Diameter over 6mm, and Evolving changes. If any mole shows one or more of these signs, it’s important to consult a healthcare provider right away.

But it’s not just moles that warrant attention. Other growths, such as actinic keratoses (scaly sun-damaged patches), basal cell carcinomas (pearly or waxy bumps), and squamous cell carcinomas (firm, red crusted lesions), may also be cancerous. Seborrheic keratoses, though often mistaken for dirt, are typically harmless.

Red flags that may indicate more serious conditions include growths that appear suddenly, grow quickly, itch persistently, bleed, or refuse to heal. Also, if a mole’s color seems to spread beyond its borders, a dermatologist’s evaluation is essential.

Performing monthly self-checks under good lighting using mirrors can help spot unusual changes early. This simple routine could be life-saving if it leads to early medical intervention.

One real-life example is Sarah, a 42-year-old teacher who ignored a suspicious mole for months. When she finally saw a doctor, she was diagnosed with melanoma. Fortunately, early treatment saved her life, and now she urges others not to delay.

Prevention is just as important as detection. Protect your skin by using broad-spectrum sunscreen, avoiding tanning beds, wearing sun-protective clothing, and staying out of direct sunlight between 10 AM and 4 PM. Understanding your family history also helps assess your personal risk level.

In conclusion, most moles are harmless, but being vigilant can save lives. Regular skin checks, attention to changes, and taking preventive steps are essential. Don’t ignore your body’s signals—your health and possibly your life may depend on quick, informed action.
