The Advanced Basal Cell Carcinoma Index (aBCCdex) measures the impact of basal cell carcinoma on patients' quality of life. The index consists of several subscales, each subscale with its own range of scores for each question Lesion Symptoms Scale: Scores range from 1 to 7 and it includes 6 questions. Therefore the total score range is from 6 (minimum) to 42 (maximum), where a higher score correlates with a poorer quality of life.
