Skin cancer is the most common type of cancer in the United States, with millions of cases diagnosed each year. According to the National Institutes of Health (NIH), basal cell carcinoma and squamous cell carcinoma are the most frequently occurring forms, with over 4 million and 1 million cases annually, respectively. These cancers originate from the epidermis, the skin’s outermost layer, and are primarily caused by ultraviolet (UV) radiation from the sun. While basal cell carcinoma tends to grow slowly and rarely spreads, squamous cell carcinoma can metastasize and be fatal in about 1% of cases if not treated promptly.
Melanoma, although less common, poses a greater threat due to its higher likelihood of spreading to other parts of the body. It arises from melanocytes, the cells responsible for skin pigmentation, and often manifests as a dark spot on the skin. Early detection is crucial for effective treatment.
Yale’s comprehensive approach to skin cancer treatment combines expertise in Mohs surgery, multidisciplinary collaboration, and cutting-edge research to identify high-risk patients and implement preventative measures. This proactive strategy aims to reduce the incidence of skin cancer through early intervention and prevention efforts.
