General Population Has Interest in Genetic Testing for Skin Cancer Risk
There is moderately high interest and follow through among the general population for genetic testing to determine melanoma skin cancer risk, according to a study published in JAMA Dermatology. However, there are difference in uptake based on socioeconomic and demographic factors, with less uptake among less educated individuals and minorities, including. The melanocortin-1 receptor gene (MC1R) is known to be associated with melanoma risk, even after adjusting for other factors like hair color and skin type. There is hope that knowledge of genetic risk may promote skin cancer awareness foster increased prevention-related behaviors (e.g., using sunscreen). Yet, to date, the direct-to-consumer testing model has primarily only reached white, highly educated consumers. Melanoma risk is known to be high among Hispanics, particularly in states with high levels of year-round sun exposure. The present study assessed prevalence of interest in and uptake of MC1R testing among internal medicine clinic patients in New Mexico. Participants were randomized to either a usual-care condition (a skin cancer pamphlet) or an MC1R test offer. Analysis included the 499 participants (44 percent white; 48 percent Hispanic) randomized to the MC1R test offer. The offer included a login for the study website, which required reading three educational modules […]
