Diagnosing Leukemia
Overview
Leukemia, is a type of blood cancer. Specialists such as hematologists or oncologists may be involved in the diagnosis process.
To diagnose leukemia, doctors use a variety of examinations, screening tests, and procedures. These include:
- Physical examination: Doctors will perform a physical examination to look for signs of infection, swelling, and bruising, which can indicate the presence of leukemia.
- Complete blood count (CBC): This test measures the amount of red blood cells, white blood cells, and platelets in the blood.
- Differential blood test: This test measures the different types of white blood cells present in the bloodstream.
- Peripheral blood smear: A drop of blood is smeared across a surface and examined under a microscope to identify cell changes that indicate leukemia.
- Flow cytometry: This test helps determine the type of leukemia by exposing blood cells to antibodies that attach themselves differently depending on whether cancer is present or not. It can also measure DNA levels in cells, indicating the potential speed of cancer growth.
- Bone marrow biopsy and aspiration: Doctors may perform a bone marrow biopsy and aspiration to examine a small amount of bone marrow tissue. This helps identify leukemic cells and determine their type and percentage in the bone marrow.
- Chromosome testing: Chromosome testing is used to check for mutations in leukemia. Specialists analyze samples from blood or bone marrow to identify atypical structures or numbers of blood cells.
Additional tests for type and stage determination include:
- Chest X-ray/CT scan: Shows how far leukemia has spread.
- PET scan: Assesses the stage of leukemia.
- Cytogenetics: Examines chromosomes to identify leukemia type.
- Spinal tap (Lumbar Puncture): Checks spinal fluid for leukemia cells.
These additional examinations, tests, or procedures help specialists determine the type, severity, or stage of leukemia by identifying specific factors or indicators. They play a crucial role in tailoring an appropriate treatment plan.
Remember that while these tests are commonly used to diagnose and determine the characteristics of leukemia, it is important to consult with a healthcare professional for an accurate diagnosis and personalized guidance.
