Breast Health Day is observed worldwide every October 15 and serves as an annual awareness campaign focused on breast health and the importance of early diagnosis of breast cancer. Established by Europa Donna – The European Breast Cancer Coalition, which was founded in 1994, the day aims to disseminate information and promote preventive measures among women and girls across Europe. The campaign was launched in 2009 in collaboration with Spanish former World No. 1 tennis player Arantxa Sánchez Vicario. On this day, various events take place in over 40 countries, utilizing social media to share vital information through videos, posters, and leaflets. Each year's campaign features a specific motto, with past themes such as “Healthy Lifestyle for Breast Health” and “Make Good Choices for Your Breast Health Every Day.”
