A nurse is assisting in planning an educational session regarding risk factors for skin cancer to a group of clients. Which of the following information should the nurse plan to include in the session? (Select all that apply.)

A. Chronic skin irritations, including scars, burns, or chronic wounds, can increase the risk of developing skin cancer, particularly squamous cell carcinoma. Repeated irritation or inflammation may promote malignant transformation of skin cells. B. Overexposure to ultraviolet (UV) light, from sunlight or artificial tanning sources, is the most significant environmental risk factor for skin cancer. UV radiation damages DNA in skin cells, increasing the likelihood of mutations and malignant transformation. C. Being dark-skinned does not increase the risk of skin cancer; in fact, higher melanin levels provide some protection against UV-induced DNA damage. Dark-skinned individuals are at lower risk than fair-skinned individuals, although skin cancer can still occur. D. Genetic predisposition increases the risk of skin cancer. A family history of melanoma or other skin cancers, or genetic syndromes such as xeroderma pigmentosum, can make individuals more susceptible. E. Age under 40 years is not a significant risk factor; the risk of most skin cancers increases with age, as cumulative UV exposure and cellular mutations accumulate over time.
