Should a mole that has protruded be removed?

Moles that pose certain risks may need to be surgically removed. Moles affecting appearance, located in areas prone to malignant transformation, or showing signs of potential malignancy should be considered for removal.

1. Affecting appearance

Moles located on the face or other exposed areas of skin may affect personal appearance and can be considered for removal at a hospital dermatology department.

2. Located in high-risk areas

Moles located in special areas such as the palms, soles, mucous membranes, or nail grooves, as well as those in areas frequently subjected to friction or irritation—such as the armpits, genital area, or waist—should be promptly evaluated at a hospital to determine whether removal is necessary, thus preventing possible malignant changes.

3. Showing signs of potential malignancy

If a mole rapidly increases in size, develops uneven or darker pigmentation, shows blurred borders with signs of infiltration or radial spread, or causes discomfort such as pain, it is important to seek immediate medical evaluation and pathological testing to determine whether malignant transformation has occurred and to initiate appropriate treatment.

Depending on the type, size, and location of the mole, different removal methods may be used. Small, superficial moles measuring 1–2 mm in diameter can often be removed using laser therapy. Moles larger than 2 mm, deeply embedded, protruding, or suspected of malignancy require surgical excision; skin grafting or flap surgery may be needed depending on the wound condition after removal. Pathological examination should always be performed after removal to confirm whether there are any malignant changes.

It is recommended to visit a hospital for comprehensive evaluation, clearly identify the nature of the mole, and follow a doctor's guidance to receive scientifically appropriate treatment.
