Hello I can understand your concern. The dermatologist would examine the mole under a dermatoscope and if then required would do a biopsy from the lesion to check whether it s a melanoma or not. I would like to give you some information regarding moles. A new or changing mole or blemish is the most common warning sign for melanoma. Variation in color and/or an increase in diameter, height, or asymmetry of borders of a pigmented lesion are noted. Symptoms such as bleeding, itching, ulceration, and pain in a pigmented lesion also warrant an evaluation. ABCDE criteria for a changing mole, which are as follows: Asymmetry: Half the lesion does not match the other half. Border irregularity: The edges are ragged, notched, or blurred. Color variegation: Pigmentation is not uniform and may display shades of tan, brown, or black; white, reddish, or blue discoloration is of particular concern. Diameter: A diameter greater than 6 mm is characteristic, although some melanomas may have smaller diameters; any growth in a nevus warrants an evaluation. Evolving: Changes in the lesion over time are characteristic. Lesions exhibiting these features should be considered potential melanoma i thought of giving you this information so you are aware of what change to expect. Hope I have answered your queries. Take care
