Most moles are harmless, but a spot that is new, changing, bleeding, or simply looks different from the rest deserves a closer look.
We examine the mole in context with your skin and history and use dermoscopy or biopsy when needed.
Benign moles can also be discussed if they are irritated or you are considering removal.
When a Mole Needs Evaluation
Moles, or nevi, are common growths made of melanocytes. Most are benign and remain stable for years, but some deserve closer evaluation because melanoma and other skin cancers can resemble ordinary moles.
What changes should I watch for?
The ABCDE guide can help identify concerning features: asymmetry, irregular borders, multiple or changing colors, larger diameter, and evolution over time. A lesion that looks different from your other moles—the “ugly duckling”—also deserves attention.
When should a mole be biopsied?
Biopsy may be recommended when a lesion has suspicious clinical or dermoscopic features, changes over time, bleeds without explanation, or causes persistent symptoms.
Can benign moles be removed?
Yes, selected benign moles can be removed if they are irritated or cosmetically bothersome. Removal method depends on size, depth, location, and whether pathology is needed.
Routine self-examination and periodic professional skin checks are especially important for patients with many moles, atypical moles, significant sun exposure, or a personal or family history of skin cancer.
If removal is appropriate, see Mole Removal for biopsy, shave removal, excision, scarring and recurrence.
