Visit the ER for serious illness or injuries when you need emergency care. Visit urgent care for minor injuries or illnesses that need same-day care.

Get the care you need from experienced medical oncologists-hematologists at Ascension Illinois in Chicago
When you choose an Ascension Illinois Cancer Care in Chicagoland, you get a team of experienced, compassionate doctors who specialize in diagnosing and treating blood cancers and blood disorders. Our care teams share best practices and the latest advances in cancer treatment and research — bringing advanced cancer care close to home.
Every appointment with your hematology-oncology team starts with a conversation focused on you. Your doctor takes time to answer your questions, understand your needs and get to know you in order to create a personalized cancer care plan. And with a plan, comes hope. We help you navigate your care at every step, connecting you with the services and support you need. Our goal is to help you get back to your everyday life, sooner.
If infusion therapy is recommended as part of your treatment plan for blood cancer or a blood disorder, you’ll receive intravenous (IV) therapy from a team of highly trained nurses and pharmacists.
Chemotherapy and other medications and fluids can be delivered at our infusion centers, through a portable infusion pump or at home by a home health care team (see Ascension at Home).
Your care team pays close attention to how you’re feeling and helps you manage symptoms between treatments. Before each treatment session, your oncologist checks your bloodwork so your medications can be tailored to your current condition and overall care plan.
Your doctor and care team explain your diagnosis and help you understand how your care plan is personalized for your condition. The most common types of blood cancer in adults include:
Our hematology-oncology specialists also diagnose and treat noncancerous blood disorders, including anemia, hemophilia and blood clots.
Your doctor may recommend:
A complete blood count is a blood test used to evaluate your overall health and help detect conditions such as anemia, infection and leukemia.
A CBC with white cell differential measures different types of white blood cells and can help evaluate infection, inflammation and some blood disorders.
Genetic testing may help you and your doctor better understand your risk for certain cancers. If you’ve been diagnosed with cancer, your doctor may recommend genetic pathology testing to identify changes in cancer cells or tumor growth that may affect treatment decisions.
Call to schedule an appointment:
Cancer research and clinical trials can give you access to new treatments, often before they become widely available. Talk to your doctor to learn whether cancer clinical trials are the right option for you.

Your care may include imaging, lab tests, pharmacy support, nutrition counseling or other specialty services. You do not have to navigate your care alone.
From your first consultation throughout ongoing care, you and your Ascension Illinois doctor stay connected through in-person and virtual visits. You'll be able to talk with your doctor one-on-one via video from your phone or computer.

When you are facing a new cancer diagnosis or are deciding on a surgical or therapeutic treatment plan, there’s a lot to think about. Our blood cancer specialists can provide a second opinion, based on our experience and as part of a national team.
Before your appointment, check with your insurance company to find out if a second opinion is covered. We can request your medical records on your behalf, so they can be shared with your care team before your arrival.
