Cancer Treatment and Support
Medical Interventions
The medical oncologists affiliated with our Cancer Center use the latest cancer-fighting drugs to treat and cure all kinds of cancer. more
IMRT (Intensity Modulated Radiation Therapy)
We work with Radiation Oncology Center of Ventura County (ROCVC) to bring an advanced radiation system, called IMRT, to Ventura County. more
LINAC Scalpel
The LINAC scalpel, a sophisticated method of treating cancer that can more effectively influence the outcome for some patients, is available at ROCVC. The device delivers a high dose of radiation to targets in the brain, with very little of the dose affecting other parts of the brain.
Prostate Cancer and Brachytherapy
ROCVC has successfully treated patients with prostate cancer with the use of Proseed, otherwise known as brachytherapy, which permanently implants radioactive seeds into the prostate gland. Proseed delivers a prescribed dose of radiation directly to the cancer cells while decreasing the risk of radiating surrounding tissues or organs.
Clinical Trials
St. John's affiliation with the UCLA Jonnson Cancer Center provides patients with access to clinical trials currently being conducted nationwide.

At the Radiation Oncology Center of Ventura County (ROCVC), located in the Medical Plaza at St. John's adjacent to St. John's Regional Medical Center in Oxnard, you will experience the outstanding, comprehensive program that uses multiple approaches to treat and eradicate cancer. ROCVC is made up of a team of specialists led by radiation oncologists Dr. Timothy O'Connor and Dr. Henry Montes, who also treat patients at their Mission Oaks office in Camarillo. The radiation oncologists are nationally recognized leaders in the field of radiotherapy, and experts in stereotactic radiosurgery.

St. John's Cancer Center of Ventura County offers an array of relaxation therapies to provide patients with spiritual tools to help fight cancer, including classes such as art expression and relaxation therapy in the tradition of Reiki, T'ai Chi Chih, yoga, guided imagery, pulse technique, and reflexology.
