Your blood plays a big role in your health, and we want to make sure it's functioning the way it should. If you have a blood disorder, we're here to help you treat it in the best possible way.

Hematology focuses on the care of patients with common disorders of the blood, bone marrow, and lymphatic systems (an important part of the immune system).

Hematologists treat issues like anemia, blood clots (thrombosis), bleeding problems, bone marrow and blood cancers (hematological malignancies) and other disorders that are either present from birth or come on over time.



A form of cancer that causes abnormal, cancerous white blood cells. Symptoms of leukemia include low energy, easy bruising and continued infections.

Clotting or bleeding disorders

These disorders prevent your body from being able to stop its bleeding effectively. Cuts or other scrapes that are slow to clot/stop bleeding, as well as premature strokes and heart attacks, are possible signs of a bleeding disorder.

Bone Marrow Disorders

These disorders are caused by your bone marrow’s stem cells, which is where your blood cells are produced. Potential symptoms of bone marrow disorders include exhaustion, bruising and infections that won’t go away.


This is when your body doesn’t have enough red blood cells, which carry oxygen throughout your body. Low energy, loss of hair and pale skin are all symptoms of anemia. Shortness of breath (without exercise) can also be a symptom.


This is when your body’s immune system, like your white blood cells, can’t defend against infections. Fevers, night sweats and infections that won’t heal are signs of immunodeficiency.

We also offer:

  • Growth factor drugs
  • Immunosuppressive drugs
  • Immunotherapy
  • Targeted drug therapy

Some specific hematology-related issues that we treat are:

  • Myelodysplastic syndromes: Disorders caused by something disrupting the production of blood cells
  • Myelofibrosis: A bone marrow disorder that disrupts the body’s normal production of blood cells
  • Myeloproliferative disorders: Slow-growing blood cancers
  • NK-cell leukemia: A rare form of leukemia
  • Neuroblastoma: A type of cancer that forms in nerve tissue
  • Non-Hodgkin’s lymphoma: Cancers that start in the lymphatic system
  • Paroxysmal nocturnal hemoglobinuria: A very rare blood disease that breaks apart red blood cells
  • Sarcoma: A tumor that affects connective tissue
  • Polycythemia vera: A slow-growing blood cancer in which the bone marrow makes too many blood cells
  • Sickle cell anemia: An inherited form of anemia in which red blood cells become misshapen and break down
  • Systemic capillary leak syndrome: A condition in which fluid and proteins leak out of blood vessels and into surrounding tissues
  • Systemic mastocytosis: A disorder that causes an excessive number of mast cells in the body
  • Thalassemia: An inherited blood disorder in which the body doesn’t make enough oxygen-carrying proteins
  • Thrombocytopenia (low platelet count): A condition caused by low amounts of the blood cells that help blood clot
  • Acute lymphocytic leukemia: The most common childhood cancer; a cancer of the blood and bone marrow that affects white blood cells
  • Acute myelogenous leukemia: Cancer of the white blood cells
  • Amyloidosis: The buildup of abnormal proteins in the liver, heart, kidneys or other organs
  • Anemia: A condition in which the blood doesn’t have enough healthy red blood cells, usually resulting in fatigue and other symptoms
  • Aplastic anemia: A rare condition in which the body stops producing enough new blood cells
  • Autoimmune hemolytic anemias: A type of anemia that occurs when the body’s immune system attacks and destroys red blood cells
  • Autoimmune thrombocytopenia: A condition caused by low levels of platelets (the blood cells that prevent bleeding)
  • Benign hematologic conditions: Common blood disorders
  • C1-esterase inhibitor deficiency: Results in angioedema (swelling), often in the respiratory or gastrointestinal tracts
  • Castleman disease: A rare disease of the lymph nodes and related tissues
  • Chronic lymphocytic, myelogenous and myelomonocytic leukemia: Diseases of the blood and bone marrow that typically get worse over time
  • Cryoglobulinemia: A disease caused by an abundance of a protein that clusters the blood
  • Cutaneous T-cell lymphoma: A cancer that attacks the skin
  • Essential thrombocythemia: A rare disorder that causes an excessive amount of platelets
  • Hairy cell leukemia: A blood cancer that causes an excess of white blood cells
  • Hemoglobinopathies: Blood disorders that affect red blood cells
  • Hemophilia: A disorder in which blood doesn’t clot properly
  • Hereditary hemolytic anemias: Anemia caused by the destruction – rather than the underproduction – of red blood cells
  • Hodgkin’s lymphoma (Hodgkin’s disease): Cancer of the part of the immune system called the lymphatic system
  • Hypereosinophilic syndrome: A group of conditions resulting in high numbers of disease-fighting white blood cells
  • Idiopathic thrombocytopenic purpura (ITP): A disorder that can lead to excessive bruising or bleeding
  • Iron-deficiency anemia
  • Large granular lymphocyte disorders: Chronic leukemia affecting white blood cells
  • Lymphoma: Cancer of the lymphatic system
  • Macroglobulinemia: A condition caused by an excess of a certain type of protein in the blood
  • Multiple myeloma: Cancer that forms in plasma white blood cells
  • Myasthenia gravis: Weakness and fatigue of the muscles under one’s voluntary control
  • Thrombocytosis: A condition caused by high platelet counts in the blood
  • Vitamin-deficiency anemia
  • White blood cell disorders
