Melanoma Monday is observed worldwide every first Monday of May, marking the beginning of National Skin Cancer Awareness Month. This annual campaign was founded by the American Academy of Dermatology, aiming to spread information about melanoma, the most dangerous type of skin cancer, and ways to reduce its risk. Participants engage in various activities such as learning about melanoma, wearing black or orange to symbolize awareness, performing self-exams, and scheduling skin cancer screenings if suspicious moles are found. The campaign encourages individuals to protect their skin from UV rays and to check for changes in existing moles, utilizing the ABCDE mnemonic for early signs of melanoma. The event highlights the importance of early detection, which significantly improves survival rates, and promotes sharing personal stories to support those affected by melanoma.
