Melanoma early detection and awareness: how countries developing melanoma awareness programs could benefit from melanoma-proficient countries

Risk factors for melanoma are well known and have guided plans for primary and secondary prevention. The presentation of the disease, however, varies widely depending on the geographic area, ethnicity, and socioeconomic status. For this reason, many countries have developed specific strategies to increase public awareness and favor early diagnosis. Awareness campaigns, doctor education, and screening of high-risk subjects have all contributed to improve disease outcome in developed countries. The role of primary care physicians is particularly relevant in this regard. Developing countries are trying to implement similar measures. Future efforts to further improve the efficacy of preventive strategies should focus on populations that usually escape campaigns, such as elderly men and people with low socioeconomic status. Fast-growing tumors also require specific attention.
