A Comprehensive Guide to Hematologic Cancer
Understanding blood cancer, recognizing possible symptoms, learning about diagnosis and exploring treatment options can help patients and families make informed healthcare decisions.
Unraveling the Enigma of Blood Cancer
Blood cancer is a complex group of diseases that affects blood cells, bone marrow and the lymphatic system.
What is Blood Cancer?
Blood cancer, also known as hematologic cancer, is a broad term used for cancers that affect the production and function of blood cells.
These cancers commonly originate in the bone marrow, where blood cells are produced, or in parts of the lymphatic and immune systems.
Red blood cells carry oxygen, white blood cells help fight infections, and platelets help the blood clot. Different blood cancers can affect these cells in different ways.
Main Types of Blood Cancer
Blood cancers are commonly grouped into three major categories.
Leukemia
Leukemia primarily affects blood-forming tissues and leads to the production of abnormal blood cells, particularly white blood cells.
Lymphoma
Lymphoma affects the lymphatic system and includes two major groups: Hodgkin lymphoma and non-Hodgkin lymphoma.
Myeloma
Myeloma mainly affects plasma cells, a type of white blood cell that normally produces antibodies to help protect the body.
Causes & Risk Factors
The exact cause of many blood cancers is not always known, but certain factors may increase risk.
Genetic Predisposition
A family history of certain blood cancers may be associated with an increased risk.
Radiation Exposure
Exposure to high levels of ionizing radiation may contribute to the development of certain blood cancers.
Chemical Exposure
Exposure to certain chemicals may be associated with increased risk of some hematologic cancers.
Infections
Certain infections, including some viral infections, have been associated with particular types of lymphoma.
Immune System Disorders
Certain conditions that affect the immune system may increase the risk of some blood cancers.
Other Factors
Risk varies significantly depending on the specific type of blood cancer and individual circumstances.
Common Symptoms
Symptoms can vary depending on the type and stage of blood cancer. Some symptoms can also occur with many other conditions.
Persistent Fatigue
Ongoing or unexplained tiredness that does not improve with adequate rest.
Frequent Infections
Repeated or persistent infections may occur when normal immune function is affected.
Unexplained Weight Loss
Sudden or unintended weight loss may occur in some people with blood cancer.
Swollen Lymph Nodes
Painless lumps or swelling in the neck, armpits or groin can occur, particularly with lymphoma.
Bruising & Bleeding
Easy bruising, nosebleeds or prolonged bleeding may occur when platelet levels are low.
Bone Pain
Bone pain, especially in the back, ribs or pelvis, may occur in some people with myeloma.
Night Sweats
Excessive sweating at night can be associated with certain lymphomas.
Diagnosis of Blood Cancer
Doctors may use blood tests, tissue sampling and imaging studies to identify and classify blood cancers.
Blood Tests
Blood tests can examine blood cell counts and identify abnormalities that may require further investigation.
Bone Marrow Biopsy
A small sample of bone marrow may be collected and examined for abnormal or cancerous cells.
Imaging Tests
CT, MRI or PET scans may be used to evaluate lymph nodes, organs and the extent of disease.
Lymph Node Biopsy
When lymphoma is suspected, a lymph node sample may be examined to determine the specific type.
Blood Cancer Treatment Options
Treatment depends on the specific cancer, stage, characteristics of the disease and the individual's overall health.
Chemotherapy
Medicines may be used to destroy cancer cells or slow their growth.
Radiation Therapy
High-energy radiation may be used to damage and destroy cancer cells.
Stem Cell Transplant
Healthy blood-forming stem cells may be used to restore bone marrow after intensive treatment.
Targeted Therapy
Medicines may target specific molecules or biological pathways involved in cancer growth.
Immunotherapy
Treatments can help the immune system recognize and fight certain cancer cells.
Watchful Waiting
For selected slow-growing cancers, careful monitoring may be appropriate before active treatment is needed.
Support for Those Affected by Blood Cancer
A blood cancer diagnosis can be overwhelming for patients, families and caregivers. Medical professionals, support organizations and community resources can provide valuable guidance throughout the journey.
Healthcare Professionals
Work closely with your oncology and hematology team to understand your diagnosis and treatment.
Family & Caregivers
Emotional and practical support from trusted people can be an important part of the care journey.
Support Organizations
Patient organizations and cancer support communities can provide education and emotional assistance.
Understanding Blood Cancer Starts With Awareness
Blood cancer is a challenging group of diseases affecting blood-forming tissues and the immune system. Learning about the different types, recognizing possible symptoms and understanding available treatment approaches can help patients and families have more informed conversations with healthcare professionals.
