Cotton O’Neil Cancer Center

If you’ve been diagnosed with cancer, chances are, you’re not only concerned, you’re feeling confused or uncertain. You might not even know where to begin with your questions — or even which questions to ask.

But you don’t need to know all of the important questions to ask us. At the Cotton O’Neil Cancer Center, we’ve walked this journey with many people just like you. That’s why we anticipate your needs and lead you through the process. We’re ready to give you information on topics, such as:

  • What’s next in your treatment
  • How you can manage symptoms or side effects
  • Where you can go for spiritual support, financial resources, or other needs
  • How you can talk to your family about your diagnosis (we’re here to answer questions from family members, too)

We’ll provide as much information as you need so that you can feel confident and assured you are doing the right thing for you.

Stormont Vail Health’s Cotton O’Neil Cancer Center is designed to provide everything patients need under one roof. In addition to clinicians, the Cancer Center houses its own treatment room, radiation oncology laboratory, radiology suite, clinical research department, and pharmacy. Patients also have access to social workers, chaplains, dietitians, and palliative medicine and survivorship care.

We always encourage our patients to stay in touch with their primary care providers so they can continue with annual physicals, screenings, and ongoing health management, and keep their bodies strong for fighting cancer.

Tai Chi for Cotton O’Neil Cancer Center Patients

Tai chi is an ancient martial art from China first used for self-defense, but it is now performed for meditation and exercise. Participants perform a series of slow, constant movements while concentrating on deep breathing in a form of meditation. This meditation helps relax the mind while strengthening the body.

Studies have found that regular practice of tai chi can provide health benefits to cancer patients and cancer survivors. These benefits may include decreased stress, anxiety, and depression; improved mood; increased energy and stamina; improved balance and flexibility; and improved strength.

Tai Chi for Patients is open to patients of the Cancer Center and is led by an instructor. To participate, contact the Cancer Center at (785) 354-5300. Please wear loose-fitting, comfortable clothing.

Meeting times:
Tuesdays at 3:30 p.m. in the lobby of the Cotton O’Neil Cancer Center

Healthy Recipes

Good nutrition is essential for cancer patients both during and after treatment, as it can help speed up recovery. The Healthy Recipes group teaches patients and their families the basics of good nutrition using recipes from the American Institute for Cancer Research.

At each meeting, patients and their families can see demonstrations of meal preparation and taste test some sample meals. They also can discuss the healthfulness of the recipes and learn what makes a good recipe. The goal is to help them branch out into making their own good food choices every day.

Healthy Recipes is for Cotton O’Neil Cancer Center patients and their families, and is provided at no cost to them.

Meeting times:
Third Thursday of each month from 12 to 1 p.m. in the conference room of the Cotton O’Neil Heart Center in the Demonstration Kitchen.

Technology at the Cotton O’Neil Cancer Center

The Linear Accelerator

We use a Trilogy linear accelerator for image-guided radiotherapy (IGRT). Trilogy delivers high-dose radiation to tumors of all sizes. It can target areas as small as a pencil point, minimizing damage to healthy tissue.

This system also allows patients to receive treatments in much less time – it delivers radiation doses more than 60 percent faster than conventional linear accelerators used to treat cancer.

The PET/CT Scan

The Cotton O’Neil Cancer Center is home to the first PET/CT in a 13-county region in northeast Kansas.

Positron emission tomography (PET) scans create images of a patient’s tissues and organs, detecting actively growing cancer cells. Computed tomography (CT) scans use X-rays to create 3D pictures of the inside of a patient’s body to show the shape and size of cancerous growths.

At the Cancer Center, we use start-of-the-art scanner technologies to perform PET and CT scans at the same time (PET/CT). Together, the PET/CT scans show highly detailed images of patients’ bodies, and give our physicians the clearest picture of the disease. PET/CT is one of the most powerful tools in diagnosing cancer, as well as learning which stage it’s in.
