Leukemia and lymphoma

Leukemia and lymphoma are cancers that affect the blood or immune system. Learn about symptoms, causes, diagnosis and available treatments. Early evaluation and coordinated care can make a difference.

Leukemia and lymphoma are cancers of the blood and immune systems. Leukemia originates in the bone marrow, producing abnormal white blood cells that circulate in the blood. Lymphoma develops in the lymphatic system, including lymph nodes, spleen, or thymus, often presenting as swollen lymph nodes or masses. Early detection and coordinated care are crucial for optimal outcomes.

Common Types

  • Leukemia: Acute lymphoblastic leukemia (ALL), acute myeloid leukemia (AML), chronic lymphocytic leukemia (CLL), chronic myeloid leukemia (CML)
  • Lymphoma: Hodgkin lymphoma, non-Hodgkin lymphoma

Symptoms

  • Persistent fatigue or weakness
  • Frequent infections or fevers
  • Unexplained weight loss or loss of appetite
  • Night sweats
  • Easy bruising, bleeding, nosebleeds, or prolonged bleeding from cuts
  • Swollen, painless lymph nodes (neck, armpit, groin)
  • Bone or joint pain (more common in leukemia)
  • Shortness of breath or pale skin from anemia

Causes and Risk Factors
Leukemia and lymphoma begin with genetic changes in blood- or lymph-forming cells, leading to uncontrolled growth. Risk factors may include:

  • Older age (for certain types)
  • Previous chemotherapy or radiation
  • Exposure to chemicals like benzene
  • Smoking
  • Genetic syndromes such as Down syndrome
  • Weakened immune system
  • Family history of blood cancers

Diagnosis
Diagnosis often starts with a physical exam, medical history, and routine blood tests (CBC with differential). Additional tests may include:

  • Peripheral blood smear
  • Bone marrow aspiration and biopsy
  • Flow cytometry and immunophenotyping
  • Cytogenetic and molecular testing
  • Imaging studies (CT, PET scans, ultrasound) to assess lymph nodes or organ involvement

Treatment Approach
At TidalHealth, a multidisciplinary team develops personalized treatment plans based on the cancer type, stage, and patient health. Treatments can include:

  • Chemotherapy
  • Targeted therapies
  • Immunotherapy (including monoclonal antibodies or CAR-T in some cases)
  • Radiation therapy
  • Bone marrow or stem cell transplantation
    Supportive care, such as transfusions, antibiotics, or growth factors, is often included.

What is the difference between leukemia and lymphoma?
Leukemia begins in the bone marrow and affects blood cells, while lymphoma arises in the lymphatic system. Both affect the immune system but start in different tissues and have distinct treatment approaches.

Are leukemia and lymphoma curable?
Some types can be cured, such as certain acute leukemias in children and Hodgkin lymphoma. Many other types are highly treatable and manageable for long periods. Prognosis depends on type, genetic features, stage, and overall health.

What treatments are available?
Options include chemotherapy, targeted therapy, immunotherapy, radiation, and bone marrow or stem cell transplantation. Supportive care is part of the overall plan.

When should I see a doctor?
Seek evaluation for symptoms such as ongoing fatigue, frequent infections, unusual bruising or bleeding, swollen lymph nodes, night sweats, or unexplained weight loss. Early evaluation improves outcomes.

Can lifestyle changes prevent these cancers?
There is no guaranteed way to prevent leukemia or lymphoma. Reducing risk factors (not smoking, limiting unnecessary radiation, avoiding harmful chemicals) and routine check-ups may help.

Support and Resources
Support may include oncology care teams, advocacy groups, counseling, nutrition guidance, rehabilitation services, and patient support groups.
