Skin cancer is one of the most common types of cancer worldwide. The disease is characterized by the uncontrolled growth of abnormal skin cells. The main cause of skin cancer is ultraviolet radiation. Hence these cancers are most often found in the body areas exposed to the sun but may also appear elsewhere. Its early diagnosis is crucial for successful treatment. The ABCDE rule is most often used for detection and characterization of melanoma in its early stages. Skin cancer diagnosis is based on the patient's family anamnesis, history of pigment changes in the skin lesions, appearance of new skin lesions, sun exposure and previously occurred sunburns. The gold standard for diagnosis is dermoscopy, but the definitive diagnosis is usually set by surgical excision and histopathological examination. Due to the large number of affected people, a wide range of noninvasive imaging methods has been developed in the field of dermatooncology in the last decades. The use of machine learning has also been on the upswing lately.
