We created a series of videos for CLL Blood Cancer. Chronic lymphocytic leukemia (CLL) is a type of cancer of the blood and bone marrow — the spongy tissue inside bones where blood cells are made. There are 3 short videos in this series about Chronic lymphocytic leukemia (CLL). This campaign was to raise awareness of the disease for patients, loved ones, caregivers, and others involved in the treatment of CLL.
