Staging

Staging is a method that doctors use to determine the progression of cancer in a patient and the best course of treatment. Doctors in the United States use the Rai staging system to classify how far your CLL has progressed. In other countries, doctors use the Binet system. Sometimes Rai stages are combined to describe a Low risk group (Rai stage 0), an Intermediate risk group (Rai stages I and II combined), and High risk group (Rai stages III and IV combined).
