World Lymphoma Awareness Day is observed worldwide every September 15. Established in 2004 by the Lymphoma Coalition, a non-profit network of 49 lymphoma patient groups, this day aims to increase public knowledge about lymphoma, one of the most common forms of cancer. Many people are unaware of the lymph nodes and the disease itself, making this observance crucial for recognizing early signs and symptoms, such as the enlargement of lymph nodes. To support this initiative, the Know Your Nodes campaign was launched in 2007 to encourage individuals to understand their lymphatic system and the first symptoms of lymphoma. Additionally, the Beacons of Hope program, initiated in 2006, provides inspiration to those affected by lymphoma.
