​​​Rush offers compassionate care for people with a variety of benign blood disorders and cancers that develop in bone marrow, blood and lymph nodes, including the following:

If you have a suspected or diagnosed cancer, we are here to help. Call (312) 563-2320 to schedule an initial visit or an appointment for a second opinion.


Physicians carefully evaluate each patient to ensure an accurate diagnosis. Some blood cancers can be diagnosed readily by taking the patient’s medical history into account, performing a physical examination and looking at blood count results. Others may take a long time and many tests, including a bone marrow study, to detect. Blood cancer specialists at Rush use some of the following tools for diagnosis:

  • Diagnostic bone marrow procedure, an analysis of bone marrow samples taken through a bone marrow biopsy.
  • Genetic testing, which may help identify people who are at an increased risk for developing certain types of cancer.
  • Ultrasound testing, high-frequency sound waves that create images of organs and other systems within the body.



Rush offers a full range of treatment for hematologic cancers, from standard therapies to innovative treatment options, and new options are being explored every day.

Clinical Trials

Physicians at Rush are involved in clinical trials evaluating new treatment options for hematologic cancers. Through clinical trials, some patients can access experimental treatments that are not otherwise available.
