Effective treatment begins with the disease state. The stage of leukemia is an extremely important factor in assessing treatment options. Most cancers are staged depending on the size and spread of the tumor. Stages of leukemia vary depending on the type of disease. Factors that affect the staging of leukemia and prognosis are the number of white blood cells, patient age, personal history of blood diseases, chromosomal mutations, bone damage, liver and spleen health.

Stage of chronic lymphocytic leukemia:

• Stage 0 (slow-growing leukemia) – an abundance of lymphocytes present in the blood (over 10,000 / mm3); at this stage, there are no symptoms;
• Stage 1 – enlarged lymph nodes and blood with an increased amount of lymphocytes;
• Stage II – excess lymphocytes in the blood and liver, spleen and lymph nodes are increased;
• Stage III – there are more blood lymphocytes than healthy red blood cells (anemia) and the liver, spleen and lymph nodes are enlarged;
• Stage IV – abundant numbers of blood lymphocytes and low red blood cell counts and platelets; livers, livers, and lymph nodes are enlarged.

Stage of acute lymphocytic leukemia (not a stage but risk groups because cancer has already spread in the body):

• Reduced risk – Children between 1-9 years with white blood cell counts of approximately 50,000 / μL at the time of diagnosis;
• High risk – Children younger than 1-year-old or older, with a leukocyte count of 50,000 / μL or higher;
• Recurrent – patients who, even after effective cancer treatment, continue to develop acute lymphocytic leukemia.

Stage of acute myeloid leukemia:

• Untreated – patients showing signs and symptoms of leukemia and diagnosed with abnormal blood count, about 20% of bone marrow cells are blasphemy;
• Remission – cancer has been treated and the patient has normal blood counts;
• Recurrent – patients who have been treated but continue to develop acute myeloid leukemia.

Stage of Chronic Myelogenous Leukemia:

• Chronic phase – Stable and slow-growing leukemia; count of blasts or immature blood cells is less than 10%;
• Accelerated phase – blasts count is approximately 10 – 19%;
• The blast phase – the stage is fast and aggressive; nearly 3 percent of the total of the sanguine cells and the bone marrow are blasted.
