Cancer Care
Treating the whole patient from prevention to diagnosis, treatment & recovery

At the Cancer Care Center of O’Fallon, our dedicated team uses the latest diagnostic technology and advanced technologies to create a comprehensive treatment plan tailored just for you. Our new, 31,000 square foot facility opened in April 2020 and is shared by HSHS St. Elizabeth’s Radiation Oncology Center and Cancer Care Specialists of Illinois to serve patients from across the region.
The cancer center features a welcoming environment and compassionate caregivers who our patients say treat them like family. Services include radiation oncology, a medical oncology physician clinic, infusion services, support and education programs and more.
St. Elizabeth’s is the only American College of Surgeons Commission on Cancer designated cancer program in the service area of St. Clair County. In addition, we have access to clinical trials, exchange information with other cancer centers across the country and maintain a cancer registry of case studies of treatments and techniques.

Specialized Oncology Services at the Cancer Care Center of O’Fallon
Always by your side
Doctors are usually delivering the cancer diagnosis, not being told they have cancer. When Dr. Reinert was diagnosed with prostate cancer, he knew he could rely on the compassionate care offered at St. Elizabeth’s Hospital.
Latest technology allows best treatment options
At the Cancer Care Center of O’Fallon, we have all the latest technologies that allow us to offer the best treatment and care to our patients in the region. We offer intensity modulated radiation therapy, which is a way of giving treatment, where we modulate the beam around the cancer itself and in the process, try to avoid normal structures. Dr. Williams says these types of technologies really contribute to decreasing side effects that we could not do when she first started in the field 15 years ago.
Being treated like family makes all the difference
We use the latest technology to create comprehensive cancer treatment plans, but our patients say it is being treated like family that makes all the difference. Michael underwent treatment for prostate cancer and was very impressed with the care he received. Listen to his story.
