Hematologic malignancies are neoplasms that affect the blood, bone marrow, and lymph nodes. Hematological malignancies are the most common forms of leukemia, lymphoma, and myeloma, with numerous subtypes. The general symptoms of leukemia are fatigue, increased susceptibility to infection, bleeding, and the formation of bruises easily. Typical lymphoma symptoms are night sweats and involuntary weight loss, recurrent fever, fatigue, and itching. Myeloma patients often have bone pain, fatigue, anemia, hypercalcemia or infection symptoms.
