Urgent care vs. the ER: How to know where to go
June 11, 2026
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.

Oncologists and care teams at Ascension St. John deliver compassionate, personalized lung cancer care
At Ascension St. John in Oklahoma, our lung cancer specialists are part of a national team of doctors who share best practices and advanced treatment options for lung and chest cancers, as well as benign lung nodules — bringing advanced oncology care close to home.
Here, you’ll receive care from a multidisciplinary team focused on early detection and personalized treatment. Your care team may include board-certified, fellowship-trained thoracic surgeons, pulmonary medicine specialists, radiologists, medical oncologists, radiation oncologists, a care navigator, and oncology nurses, dietitians and other specialists.
Together, your care team delivers a personalized care plan from diagnosis through survivorship.
Cancer is personal, and so is the way we care for you. You’ll have face-to-face visits with your doctor and have an entire care team — connecting the dots for you. Your doctor and care team will take the time to answer all your questions — big and small. By getting to know you and working together, you get a care plan that’s customized to your needs. And with a plan, comes hope. Our goal is to help you recover faster so you can get back to your daily life.
Along the way, your care may include imaging, lab tests, pharmacy support, respiratory therapy, physical therapy or other specialty services — you do not have to navigate your care alone. Upon your cancer diagnosis or when you come to us during your cancer care, you’re paired with a cancer care navigator.
Your care team will help you schedule appointments, connect you with other services and answer questions. When you have a concern or feel unsure, don’t hesitate to talk with your care team.
Ask about virtual care (telehealth or online) appointments as part of your ongoing care. You can have these virtual visits from the comfort of your home. You'll be able to talk with your doctor one-on-one via video from your phone or computer and get the care that's right for you.
There are several types of lung cancer, and they all have different treatment plans. Our lung cancer specialists in Oklahoma deliver a customized care plan for your cancer. We treat many types of lung and chest cancers, including:
The first step is to find out if a low-dose CT lung screening is right for you. Talk with your doctor if you need help to stop smoking — they can help.
We recommend annual low-dose CT screenings for:
Chest X-rays use low doses of radiation to make images of your tissues, bones and organs, and are used to look for a tumor or cancer.
We offer imaging locations close to home — from dedicated low-dose CT lung screening to minimally invasive, image-guided lung biopsy.
A PET scan is a type of nuclear medicine scan that can show differences in the activity of the tissues in your body. It uses a tiny amount of a radioactive substance attached to sugar. (This is called a radionuclide or a radiopharmaceutical or radioactive tracer.) The tracer is put into your blood. Over an hour or so, it collects in super-active cells, like cancer cells. Then a special scanner is used to see where the tracer has collected in your body.
PET and CT scans are often done together (called a PET/CT scan).
When you are facing a new lung cancer diagnosis or are deciding on a surgical or therapeutic treatment plan, there’s a lot to think about. Our lung cancer specialists in Oklahoma 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.
Your doctor and care team get to know you well, and you’ll receive care for the whole person — from physical health and well-being to mental and emotional health. At Ascension St. John, we provide innovative medication treatments, the latest surgical technologies and techniques, high-tech radiation facilities and support services. You get a national team of experienced cancer specialists, sharing best practices and the latest in cancer care knowledge and research.
