Welcome to “The Short Course on Basic Biology of CLL!”
Action Items for Basic Biology

Learn about the normal structure and function of the lymphocytes that become cancerous in CLL/SLL.
Learn more about where we find them beyond the blood stream, namely in the bone marrow, the lymph nodes, and the spleen.

Understand what is meant by chronic versus acute leukemias and when we say that cancer is clonal.
