A nurse is reinforcing teaching to a client about skin cancer. Which of the following statements by the client indicates a need for further teaching?

A. Eating a high-fiber diet is not linked to reduced risk of skin cancer. Skin cancer prevention focuses primarily on limiting ultraviolet (UV) exposure and monitoring the skin for changes. The statement indicates a misunderstanding of evidence-based preventive strategies and requires further teaching. B. This statement is accurate. Sunscreen should be applied even on cloudy days because up to 80% of UV radiation can penetrate clouds, contributing to cumulative sun damage over time. Consistent use of broad-spectrum sunscreen is a key preventive measure against both melanoma and nonmelanoma skin cancers. C. Avoiding tanning booths is correct. Artificial UV exposure, such as from tanning beds, is a well-established risk factor for melanoma and other skin cancers. Tanning beds emit concentrated UVA and UVB rays, which accelerate skin aging and DNA damage. Education reinforces that there is no safe level of tanning bed use. D. Performing monthly skin self-examinations is recommended and accurate. Regular monitoring allows early detection of changes in existing moles or the appearance of new lesions. Early identification of suspicious changes, such as asymmetry, border irregularity, color variation, diameter >6 mm, or evolving lesions (ABCDE criteria), is critical for prompt evaluation and treatment.
