Hematology FAQ

A hematologist is a doctor who treats blood diseases and disorders. They also do tests to find out what’s wrong and plan your treatment.

Some common blood conditions hematologists treat include:

  • Anemia
  • Blood clots
  • Cancers like leukemia and lymphoma

Not always. Seeing a hematologist means you have a blood problem that needs to be checked. It could be something like anemia or a blood clot, which are not cancer.

Common symptoms of blood disorders can include:

  • Bleeding a lot
  • Bruising easily
  • Feeling very tired
  • Getting sick often
  • Having pale skin
  • Trouble breathing or dizziness

You might see a hematologist if you have signs of a blood problem, like anemia, blood clots or low platelets. Your regular doctor might send you if they think you need special care.

Hematology testing is when doctors check your blood to see if you have a blood disorder.

Tests can look at your red blood cells, white blood cells and platelets. They can also check for signs of cancer in your blood.

Anemia is a condition where the body lacks enough healthy red blood cells to carry adequate oxygen to tissues.

Causes of anemia include:

  • Blood loss (for example, from menstruation or gastrointestinal bleeding)
  • Bone marrow disorders
  • Chronic diseases
  • Iron deficiency
  • Vitamin B12 or folate deficiency

A low platelet count can lead to easy bruising, bleeding gums or prolonged bleeding. It may be caused by:

  • Autoimmune conditions, such as immune thrombocytopenia
  • Bone marrow disorders
  • Certain medications
  • Viral infections 

Both leukemia and lymphoma are types of blood cancer.

  • Leukemia: Affects blood and bone marrow, often involving abnormal white blood cells.
  • Lymphoma: Affects the lymphatic system, including lymph nodes and spleen.

Treatment and prognosis vary depending on the type and stage.
