Random Acts of Light Day – June 13, 2025

As part of the Leukemia and Lymphoma Society’s ‘Light The Night Walks’ fundraising campaign, Random Acts of Light Day is celebrated every year on June 13. This day encourages us to do a random act of kindness to bring light into the life of someone suffering from cancer. People observe the day by volunteering at hospitals, reading up on treatments and cures for blood cancer patients, or joining the Leukemia and Lymphoma Society’s Light The Night Walks to raise funds and increase awareness about leukemia and lymphoma. Random Acts of Light Day aims to make the world a kinder place for cancer patients and their families.

History of Random Acts of Light Day

Random Acts of Light Day was started by the Leukemia and Lymphoma Society (LLS), which is the world’s largest voluntary health agency for blood cancer patients. On this day, observers are expected to bring light to patients suffering from blood- and other cancers. It is not unusual to see celebrities turning up at hospitals and volunteer centers to visit patients and survivors of blood cancer and surprising them. But you don’t have to be a celebrity to observe the day — anyone who’s willing to do a kind act can participate in Random Acts of Light Day!

The day was created to raise awareness and educate the masses about blood cancer and its possible treatments. It is also a day to advocate for the need to fund research for blood cancer so that patients can have access to treatments and live a more comfortable life. Blood cancer is the third most common deadly type of cancer in the United States. Data shows that every nine minutes, a life is lost to blood cancer — that’s almost 160 deaths a day. Approximately 1.3 million people in the United States suffer from blood cancer. The three main types of blood cancer are leukemia, lymphoma, and myeloma. Leukemia is a cancer of the blood and the marrow, and it can be either acute or chronic. Acute leukemia spreads quickly while chronic leukemia progresses at a slower pace. In fact, it is the most common cancer among those under 20 and above the age of 60.
