Blood cancer is primarily called leukemia, lymphoma, or myeloma, each affecting different blood cells and tissues.
Understanding What Is Blood Cancer Called?
Blood cancer is a broad term that refers to cancers affecting the blood, bone marrow, and lymphatic system. Unlike solid tumors that form lumps or masses in organs, blood cancers impact the production and function of blood cells. The three main types of blood cancer are leukemia, lymphoma, and myeloma. Each type targets specific cells within the blood or immune system, leading to distinct symptoms and treatment approaches.
Leukemia originates in the bone marrow and leads to the overproduction of abnormal white blood cells. Lymphoma affects the lymphatic system, which is part of the immune defense network. Myeloma involves malignant plasma cells in the bone marrow. Recognizing these distinctions helps clarify what is blood cancer called and why it matters for diagnosis and therapy.
Leukemia: The First Face of Blood Cancer
Leukemia is often what people think of first when asked what is blood cancer called. It’s a cancer of the bone marrow where abnormal white blood cells multiply uncontrollably. These malignant cells crowd out healthy blood cells, impairing immunity and oxygen transport.
There are several subtypes of leukemia:
- Acute Lymphoblastic Leukemia (ALL): Rapid progression affecting lymphoid cells, common in children.
- Acute Myeloid Leukemia (AML): Fast-growing cancer involving myeloid cells; more common in adults.
- Chronic Lymphocytic Leukemia (CLL): Slow-growing leukemia affecting mature lymphocytes, mostly seen in older adults.
- Chronic Myeloid Leukemia (CML): Characterized by increased myeloid cells with a genetic abnormality called Philadelphia chromosome.
Symptoms typically include fatigue, frequent infections, easy bruising or bleeding, and swollen lymph nodes. Diagnosis involves blood tests showing abnormal cell counts and bone marrow biopsies confirming malignant proliferation.
Treatment Approaches for Leukemia
Treatment depends on leukemia type and patient factors but generally includes chemotherapy as frontline therapy to kill cancerous cells. Targeted therapies like tyrosine kinase inhibitors revolutionized CML treatment by specifically blocking cancer-causing proteins.
Bone marrow or stem cell transplantation offers potential cures by replacing diseased marrow with healthy donor cells. Radiation therapy may be used selectively to control localized disease or prepare for transplant.
Lymphoma: Cancer of the Lymphatic System
Lymphoma is another major category answering what is blood cancer called. It arises from lymphocytes—white blood cells crucial for immune response—located mostly in lymph nodes but also in other organs.
Two main types dominate:
- Hodgkin Lymphoma: Distinguished by Reed-Sternberg giant cells under a microscope; tends to affect younger adults.
- Non-Hodgkin Lymphoma (NHL): A diverse group with many subtypes varying widely in aggressiveness and treatment response.
Symptoms often include painless swelling of lymph nodes, night sweats, unexplained weight loss, fever, and fatigue. Imaging scans like CT or PET help locate involved nodes while biopsy confirms diagnosis.
Treatment Modalities for Lymphoma
Lymphomas respond well to chemotherapy regimens tailored to subtype severity. Radiation therapy targets bulky disease areas. Immunotherapy has become a game-changer; monoclonal antibodies such as rituximab attack specific lymphoma cell markers improving survival rates drastically.
Stem cell transplantation may be considered for relapsed or aggressive cases. Advances in CAR-T cell therapy—genetically engineered immune cells—show promise for refractory lymphoma patients.
Myeloma: Plasma Cell Malignancy Explained
Myeloma is a less common but significant form answering what is blood cancer called. It involves malignant plasma cells—antibody-producing white blood cells—infiltrating bone marrow causing damage to bones and impairing normal immunity.
Key features include:
- Bone pain due to lytic lesions from plasma cell infiltration.
- Anemia from marrow crowding.
- High calcium levels due to bone breakdown.
- Kidney dysfunction from abnormal proteins produced by myeloma cells.
Diagnosis requires serum protein electrophoresis detecting monoclonal protein spikes along with bone marrow biopsy confirming malignant plasma cell percentage.
Treatment Strategies for Myeloma
Treatment has evolved significantly with proteasome inhibitors like bortezomib disrupting cancer cell protein degradation pathways. Immunomodulatory drugs such as lenalidomide enhance immune attack on myeloma.
High-dose chemotherapy followed by autologous stem cell transplantation remains standard for eligible patients offering prolonged remission periods. Supportive care focuses on managing bone health with bisphosphonates and preventing infections.
The Differences Among Blood Cancers at a Glance
| Cancer Type | Main Affected Cells/Tissues | Typical Symptoms & Signs |
|---|---|---|
| Leukemia | Bone marrow white blood cell precursors | Anemia, infections, bruising/bleeding, swollen lymph nodes |
| Lymphoma | Lymphocytes within lymph nodes & lymphatic tissues | Painless swollen lymph nodes, fever, night sweats, weight loss |
| Myeloma | Plasma cells in bone marrow producing antibodies | Bone pain/fractures, anemia, kidney issues, high calcium levels |
