Hi, any pigmented skin lesion that looks suspicious should be consulted with your doctor. Signs favouring malignancy are: changing in size or shape with time ulcerating uneven color of the lesion bizarre appearance.
Thank you for the question. If a mole is suspicious or looks irregular, the doctor will do a biopsy and send the mole for histological testing. During the biopsy, the mole is removed surgically under local anaesthesia and the specimen sent for histology. Based on the histology, it can be determined if the mole is cancerous or benign.
