Hematological Malignancies | Community Health

Hematological malignancies are a group of cancers that affect the blood, bone marrow, lymph, and lymphatic system, often requiring a multidisciplinary approach to diagnosis and treatment. These malignancies, including leukemias, lymphomas, and myelomas, are closely related due to the interconnectedness of the circulatory and immune systems. With chromosomal translocations being a common cause, hematological malignancies are typically treated by specialists in hematology and/or oncology. According to the World Health Organization (WHO), approximately 1.24 million people worldwide were diagnosed with a hematological malignancy in 2020, with the incidence expected to rise by 10% annually. The American Cancer Society estimates that in 2022, over 175,000 new cases of hematological malignancies were diagnosed in the United States alone, highlighting the need for continued research and advancements in treatment options, such as bone marrow transplantation and targeted therapies, as discussed by the National Institute of Health (NIH) and the Mayo Clinic.
