The Skin Cancer Prevention Working Group is a multi-center collaboration of experts dedicated to the prevention of skin cancer. The Working Group consists of clinical and research specialists that have spent years investigating and understanding the diagnosis and management of melanoma and non-melanoma skin cancer.


The mission of the Working Group is to cultivate and analyze evidence-based research to better understand skin cancer pathophysiology, treatment, and prevention in order to be leaders in skin health education.

is a malignant cancer of cells that normally give color to our skin. Every year the overall incidence of melanoma continues to increase with over 80,000 new cases of melanoma diagnosed in 2019 alone and at least 8000 annual deaths from melanoma. While melanoma tends to be more common among Caucasians, individuals with darker skin types with melanoma tend to have worse outcomes. Furthermore, although more common with advanced age, melanoma is the second most common cancer among women age 15-29. If caught early, melanomas can be removed and followed closely; however delays in detection are tied to worse outcomes and increase the likelihood of early death.

There are many risk factors that increase the chances of developing melanoma including increased ultraviolet (UV) exposure, age, having red hair, blue eyes and/or lighter skin, a history of blistering sun burns prior to puberty and comorbid conditions or medications that weaken the immune system. Of these factors, UV radiation contributes to approximately 90% of cutaneous melanomas. 

One of the best ways minimize the harmful effects of UV radiation is by using sunscreen. By using about a shot glass worth of sunscreen with at least an sun-protection factor (SPF) 30 or higher rating, individuals can significantly reduce the UV damage and sun burns.

Another thing people can do is perform regular self-examinations of their skin. Using the “ABCDE”s of melanoma (A – asymmetry, B – irregular borders, C – color variegation, D – diameter greater than 6mm, E – evolution or change) can help identify worrisome spots that can be pointed out to your board-certified dermatologist for further evaluation.



are the most commonly diagnosed skin cancers, with over 1 million new cases diagnosed each year. They can further be categorized as basal cell carcinomas, which account for approximately 80% of NMSC, and cutaneous squamous cell carcinomas, which have a slighter greater risk of spreading to other parts of the body. NMSC grow after years of chronic exposure to UV radiation or environmental/occupational chemical exposures and are usually on sun-exposed areas including face, neck, scalp, and dorsal arms. Additional risk factors for developing NMSC include lighter skin types, sun-damaged skin, advanced age, and a weakened immune system.

While NMSC carries a lesser risk of distant metastases than cutaneous melanoma, more aggressive forms of NMSC are known to spread to other organs in the body after causing severe local tissue destruction. Worrisome signs of a potential non-melanoma skin cancer include a pearly skin lesion (usually a basal cell skin cancer) or a rough, scaly spot (a squamous cell skin cancer) that continues to grow, bleed, or causes pain and should be discussed with a board-certified dermatologist to determine the best treatment course.
