Blood cancer, also known as hematologic cancer, is a group of cancers that affect the blood, bone marrow, and lymphatic system. These cancers interfere with the production and function of blood cells, often resulting in abnormal growth of white blood cells, red blood cells, or platelets. The three main types of blood cancer are:
- Leukemia: A cancer that originates in the blood and bone marrow, leading to an overproduction of abnormal white blood cells that hinder normal blood function.
- Lymphoma: A cancer that affects the lymphatic system, which is part of the immune system. It primarily involves lymphocytes (a type of white blood cell).
- Myeloma: A cancer of the plasma cells, a type of white blood cell responsible for producing antibodies to help fight infections.
Blood cancer disrupts the body's ability to fight infections, control bleeding, and deliver oxygen efficiently. Treatment may include chemotherapy, radiation therapy, targeted therapy, immunotherapy, or stem cell transplants.
