Hematology and Oncology

Care for Blood-related Illness & Cancer

Hematology is the branch of medicine devoted to the study of blood. Two common blood disorders treated by hematologists include:

  • anemia (prolonged state of weakness)
  • hemophilia (bleeding that won't stop)

Oncology is the study of cancer, a class of diseases that causes uncontrolled growth of cells. Some cancers are benign, which means they don't invade or hurt other areas of the body. Some cancers are malignant, which means the tumor (mass of cells) destroys or invades other areas. While these two specialties are separate, they commonly overlap. Specialists in each frequently work together to provide integrated care. For instance, bone marrow transplants are blood related, but may be used in treating some cancers. Also, some blood tests are used to identify some forms of cancer. Your primary care provider will refer you to a hematologist or oncologist if your condition requires this specialized care.
