Celebrating a proton therapy treatment milestone for Middle Tennessee


On August 25, 2020, Jason W. eagerly rang the victory bell to mark the completion of his tonsil cancer treatment. In doing so, he became the 500th patient to complete treatment at Provision CARES Proton Therapy Nashville, reminding us all that cancer and cancer treatment do not delay during a global pandemic.


When Jason was told he would need radiation therapy as part of his tonsil cancer treatment plan, he consulted multiple physicians to discuss his options. Those included traditional x-ray radiation and proton therapy.

It doesn’t take a rocket scientist to make that decision.”

Dr. Josh Mondschein, a Radiation Oncologist at Provision CARES Proton Therapy Nashville, oversaw Jason’s treatment, which focused on destroying the cancer cells and minimizing side effects by avoiding unnecessary radiation exposure to critical structures in the head, neck and throat.

Proton therapy can be an ideal treatment for many head, neck, and oral cancers, including tonsil cancer. Its ability to precisely target the tumor can help patients maintain better nutritional health by improving their ability to swallow and reducing the risk of needing a feeding tube.

“It has been a privilege to serve as Jason’s treating physician, and work alongside a team that makes a difference in the lives of cancer patients and their families every day,” remarked Dr. Mondschein.


To celebrate his tonsil cancer treatment completion, Jason and his wife, Maria, along with members of the Provision CARES team, held a small, socially distant graduation ceremony at our Nashville proton center. With visitor limitations in place as a safety precaution, other members of his family joined the gathering virtually through FaceTime.

The hospitality team at Provision presented Jason with a certificate commemorating the milestone, as well as a card signed by staff members who had come to know and love him over the course of his treatment.

“We have just loved having Jason here. He brought a lot of energy into this place,” said Molly E., Hospitality Coordinator for Provision CARES Proton Therapy Nashville. “For someone going through such a challenging treatment, to see his smile every day and hear all his stories – it’s just brought a lot of joy to all of us.”

To cap off the ceremony, Jason rang the victory bell three times. It’s a tradition for cancer patients that’s thought to have been started in 1996 by U.S. Navy Rear Admiral Irve Le Moyne. As Le Moyne was nearing the end of his cancer treatment, he told his doctor he wanted to uphold a Navy tradition and ring a bell “when the job was done.” Now, 500 proton therapy patients have rung the bell at Provision CARES Proton Therapy Nashville.

Provision prides itself on our Culture of CARE, which focuses on the dignity and value of every person. Jason said the culture was evident during his time at the proton center. “The care I’ve received at Provision has been excellent. The people’s attitude there is positive, and the overall atmosphere is welcoming, warm, and friendly. I just want to thank everyone there from the bottom of my heart.”


The completed treatment of Provision’s 500th patient is a significant achievement in our mission to expand patient access to proton therapy across the country, and the globe.

“As the first and only proton therapy treatment provider in Nashville, we have been well received by our partner, Tennessee Oncology, and by cancer patients in this region, who are seeking cancer treatment options,” said Mary Lou DuBois, President of Provision CARES Proton Therapy Nashville.

Since October 2018, middle Tennesseans have had access to one of the world’s most advanced forms of cancer treatment. Proton therapy precisely targets the tumor and lowers the risk of damage to nearby healthy tissue and organs, thereby reducing side effects, complications, and the risk of developing another cancer.

Access to proton therapy has grown since first coming to Tennessee in January 2014. At that time, there were only 13 operating proton centers in the country. As of August 2020, there are 35 operating centers, with many more in development.

On April 25, 2019, Tennessee Governor Bill Lee signed into law the “Proton Therapy Access Act” that expanded insurance coverage of proton therapy to members on the Tennessee state benefit plan, effective January 2020. This legislation will benefit thousands of lives in Tennessee.
