ABOUT SKIN TUMOR

About skin lesions

What may generally be called a “skin growth” can be classified medically into moles, actinic keratoses, seborrheic keratoses, skin tags and other conditions.

The examples above are benign tumors, but a lesion can sometimes be malignant, such as basal cell carcinoma, squamous cell carcinoma or malignant melanoma.

A medical examination is recommended if there are changes that may suggest malignancy, such as rapid growth, an irregular shape, pain or bleeding.

Even when a lesion is not malignant, treatment may be considered if it is gradually enlarging, is troublesome because of its location or causes concern about appearance.

TREATMENT

Treatment options for skin tumors and moles

The two main treatment approaches are surgical excision and laser removal.

1

Surgical excision

The lesion is excised and examined histologically when necessary. The treatment plan is based on its size, location and shape, and whether malignancy is suspected.

2

Laser removal

Laser removal may be considered depending on the lesion. Treatment may also be selected after considering its location, size and clinical course.
