Wellstar Cobb Cancer Center Expands Treatment Services

Published on May 28, 2025

Last updated 09:35 AM May 28, 2025

New radiation technology and refreshed waiting and treatment areas are expanding world-class cancer treatment at Wellstar Cobb Cancer Center.

Cancer care in forward motion

Wellstar Cobb Cancer Center recently installed its second TrueBeam linear accelerator, which treats various cancers, including brain, head and neck, prostate, breast, lung, skin and gastrointestinal tumors. With the linear accelerator, clinicians can adjust the size and shape of beams to a tumor’s shape and spare healthy tissue.

With the second linear accelerator, Wellstar Cobb can offer patients more flexible and convenient scheduling. “An additional linear accelerator can lead to timely treatment starts and shorter wait times,” said Dr. Nasarachi Onyeuku, a radiation oncologist at Wellstar. “It expands our ability to treat more patients with cutting-edge care, continuing our commitment to bringing world-class cancer treatment closer to home.”

In addition to state-of-the-art external beam radiotherapy, TrueBeam delivers precise, high-dose stereotactic body radiotherapy (SBRT) targeting tumors in the body. It also provides stereotactic radiosurgery (SRS) for brain or spine cancer treatment. Patients will typically receive one to five treatments.

Patient-centered care at Wellstar Cobb

Wellstar Cobb Cancer Center recently renovated its treatment areas, front desk and waiting room, making it more welcoming and comforting for patients and their families. Within the treatment areas, the suite where patients receive high-dose radiation brachytherapy, a targeted treatment that involves placing radioactive material directly into tumors or near them, also underwent renovations.

“The beautifully designed space enhances patient comfort, offering a calm, supportive environment,” Dr. Onyeuku said. “We’re currently treating breast, cervical, uterine and skin cancers, with plans to expand to other cancer types. It’s advanced, efficient care—delivered close to home and with compassion.”

Early detection and support services

Cancer care begins with prevention and early detection. Wellstar Cobb is home to a lung cancer STAT Clinic, where specialists collaborate to diagnose and begin treatment within as little as 14 days. According to research by the Cleveland Clinic, patients can spend up to eight weeks on average visiting different specialists before starting a treatment plan. Earlier treatment can lead to the best possible outcomes.

Patients at Wellstar Cobb receive support at every stage of their treatment. These services include:

  • Emotional support from a social worker
  • Lymphedema therapy for patients with excess fluid and swelling
  • Meal planning with a dietitian
  • Monthly support group
  • Pain management
  • Physical therapy
  • Transportation assistance

“We have a superb team and state-of-the-art treatment here at Wellstar Cobb Cancer Center. And we’re backed by the resources of a nationally recognized health system,” Dr. Onyeuku said. “We are thrilled that our technology enhancements allow us to serve more people with exceptional cancer treatment.”

Wellstar PeopleCare | Reaching New Heights After Head & Neck Cancer

David Butler's cancer journey took him through a rare jaw reconstruction, multiple rounds of radiation treatment, chemotherapy, intense rehabilitation and coordinated care from specialists across Wellstar.

From survival to summit

After David did the hard work of fighting cancer twice and feeling like recovery was truly sailing along, he set a new goal. David and one of his daughters, Madeline Hawkins, completed a hiking and camping trip that included summiting Blood Mountain in North Georgia. They covered 14 miles, camping overnight and making friends along the trail.

Fully loaded with walking sticks, packs on their backs and huge smiles, David and his daughter head out for a multiple day hiking excursion.

The hike wasn't easy.

“I forgot you have to be half mountain goat!” he quipped.

David moved at his own pace and pushed through lingering fatigue. Reaching the summit’s stunning vista at Preacher’s Rock was a reminder of how far he had come since his cancer diagnosis.

Wellstar PeopleCare | Beating Cancer Twice with Coordinated Care

David Butler’s cancer journey began when he underwent treatment for an aggressive head and neck cancer. Supported by his family, faith and a team of head and neck cancer specialists, he had part of his jaw removed and went through radiation therapy and intense rehabilitation.

A major setback

The same year of his jaw surgery and initial radiation course, David’s recovery was beginning to feel like “smooth sailing.” Just as life started to feel manageable again, he faced an unexpected challenge.

David and his wife, Jill, got devastating news: routine follow-up imaging revealed three new tumors on the other side of his neck and tongue. Dr. Fiyin Sokoya, David’s cancer surgeon, removed lymph nodes from David’s neck, had them biopsied and confirmed that it was an aggressive cancer.

At first, David felt so discouraged that he didn’t want to move forward with treatment.

However, seeing that a group of experts were working together to give him the best, evidence-based treatment path for his unique circumstance gave him confidence to renew his fight against cancer.

Wellstar PeopleCare | Moving Fast, Working Together: Advanced Head & Neck Cancer Surgery Keeps David Smiling

David Butler's cancer journey took him through a rare jaw reconstruction, radiation and coordinated care from specialists across Wellstar. His care team collaborated to provide what he needed as quickly and efficiently as possible.

A bothersome mouth sore

Lean and energetic, David is quick with a joke and even quicker with a smile. A neatly trimmed mustache frames a grin that lights up his blue eyes, illuminating his trademark optimism and humor. They’re qualities he kept intact throughout cancer treatment and draws on today, when he encourages people who are newly diagnosed with cancer.

It started with a sore on his gum in the fall of 2023. He assumed it would heal on its own. Instead, it got worse. When he could hardly swallow a few months later, his dentist referred him to an oral surgeon for a biopsy. That’s when he got the life-changing news: it was cancer.

“You hear the big C and it scares you to death,” David said. “But there's light at the end of the tunnel. There's always hope.”

What followed was cancer treatment involving surgery, radiation, chemotherapy and support from a whole team of cancer specialists. Along the way, David said he leaned on his faith, the support of his wife, Jill, who he credits as his biggest advocate—and the expertise of Wellstar caregivers.
