Abstract

Background: Previous research has shown an increase in photodamage and precancers on the left side of the face. Objective: We sought to determine whether there is a higher frequency of skin cancer development on the left side of the body than the right. Methods: The study was a retrospective review of patients with skin cancer referred to our Mohs micrographic surgery and cutaneous oncology unit in 2004. Results: When including all types of skin cancers and both sexes, more cancers occurred on the left (52.6%) than the right (47.4%) (P = .059), with a stronger trend in men (P = .042). There were significantly more malignant melanoma in situ on the left (31/42, 74%) than the right (11/42, 26%) (P = .002). Limitations: Population was comprised of patients referred to an academic medical center and often for Mohs micrographic surgery. Conclusions: There were significantly more skin cancers on the left than the right side in men. This discrepancy was even more profound in malignant melanoma in situ.
