Leukemia Symptoms. Leukemia is actually a group of different cancers of the blood cells. Leukemias can be acute or chronic, and people with chronic leukemias may not notice any symptoms before the condition is diagnosed with a blood test.

Symptoms of leukemia include fevers, night sweats, and swollen lymph nodes that are typically not painful or tender.
