Blood cancers can be rooted in the bone marrow (where blood is produced), in the blood, or in the lymph nodes. There are three types of blood cells: Red blood cells, white blood cells and platelets. Most blood cancers occur when normal blood cell development is interrupted by uncontrolled growth of an abnormal blood cell type (cancerous cells).
As these diseased blood cells proliferate, they cause life-threatening damage to the immune and circulatory systems and prevent your blood from performing vital functions like fighting infections or preventing serious bleeding.
Leukemia, lymphoma and other types of blood cancers
There are three main types of blood cancers:
Leukemia – When abnormal white blood cells in the blood and bone marrow rapidly produce, they are unable to fight infection. The excessive number of abnormal white blood cells also interferes with the bone marrow’s ability to produce red blood cells and platelets.
Lymphoma – Lymphocytes are a type of white blood cell that fights infection. When abnormal lymphocytes become lymphoma cells, they multiply and collect in the lymph nodes and tissues, damaging the immune system. Hodgkin lymphoma generally starts in blood and bone marrow. Non-Hodgkin lymphoma typically begins in lymph node and lymphatic tissue.
Myeloma – Myeloma is cancer of the plasma cells, which prevents the healthy production of antibodies, weakening the immune system and making it susceptible to infection.
Blood cancer warning signs
Blood cancers can manifest in different ways. Some of the most common symptoms include:
Unexplained weight loss
Fatigue, weakness or breathlessness
Bruising or bleeding easily
Enlarged lymph nodes (may indicate lymphoma)
Swollen stomach or abdominal discomfort
Frequent and repeated infections
Fever or night sweats
Pain in bones or joints, especially the ribs or back (may indicate myeloma)
