The American Cancer Society co-founded it in 1985 in partnership with Imperial Chemical Industries as a week-long campaign to promote mammography for early detection. It expanded to a full month and became an international observance symbolized by the pink ribbon.
October is Breast Cancer Awareness Month and it's time to get involved! This month-long event has been held since 1985, when the Susan G. Komen Foundation began its fight against breast cancer by launching its first Race for the Cure in Dallas, Texas. Since then, millions of people around the world have come together to raise awareness and money for research into this life-threatening disease. From participating in fundraising events to wearing pink ribbons and showing your support online, there are so many ways you can help make a difference this October. Let's join forces and show our collective strength against breast cancer!

WHY THIS DAY MATTERS
Breast Cancer Awareness Month not only increases knowledge about the disease but also brings together survivors, advocates and supporters around a unifying cause. This can offer individuals facing their own personal struggles comfort and strength in knowing they don't have to face it alone.
Breast Cancer Awareness Month is an important reminder to people all over the world that breast cancer is a serious issue that affects both women and men. By increasing public understanding of the disease, we are better equipped to spot the signs early and get appropriate treatment if necessary.
With increased awareness comes increased donations to organizations that support research into treatments and cures for breast cancer. These donations go a long way in helping scientists find innovative ways to detect and fight the disease, which can ultimately save lives.
