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 Health System to Acquire Mountain Lakes Medical Center

CLAYTON, Ga. (June 5, 2026) — Wellstar Health System and Mountain Lakes Medical Center (MLMC) today announced that they have finalized an agreement for Wellstar to acquire the northeast Georgia-based hospital. The transaction is expected to close August 1, pending the conclusion of regulatory requirements and customary closing conditions.

Mountain Lakes Medical Center is a 25-bed critical access hospital serving Rabun County and surrounding northeast Georgia communities. After the acquisition, MLMC will become Wellstar Mountain Lakes Medical Center and join Wellstar’s integrated health system network across Georgia.

“From our earliest conversations, it was clear that Mountain Lakes Medical Center was a special organization with a talented team, deep community roots and tremendous potential,” said Wellstar President and CEO Ketul J. Patel. “We collaboratively pursued this opportunity to build on the hospital’s strong foundation and create new possibilities for patients, clinicians and communities in Rabun County and beyond.”

Patel said the acquisition reflects Wellstar’s broader vision of enhancing patient care across Georgia and the Southeast.

“At Wellstar, we’re building a connected healthcare ecosystem that links community hospitals, physicians, specialists, advanced clinical programs and digital capabilities into a seamless experience for patients. We believe MLMC has an important role to play in that future.”

MLMC leaders said becoming part of Wellstar positions the hospital to continue growing while preserving its commitment to serving the local community.

“MLMC has long served as an important healthcare resource for Rabun County and the surrounding area,” said Mountain Lakes Medical Center CEO Kristy Hall. “We believe joining Wellstar creates exciting opportunities to build on that success while connecting our patients and clinicians to additional expertise, technology, specialty resources and healthcare capabilities that can help support the future of healthcare in northeast Georgia.”

Wellstar and MLMC emphasized that patients will continue to have access to the clinicians and care teams they know and trust. Wellstar intends to take a phased and thoughtful approach to integration that prioritizes continuity for patients, clinicians and team members.

As part of Wellstar, MLMC will gain access to broader clinical expertise, advanced clinical programs, technology resources and operational support. Over time, patients and clinicians will also benefit from Wellstar’s Digital Care Network, which connects local care teams with specialists and advanced clinical programs across the system in real time, helping accelerate diagnosis, treatment planning and coordinated care.

The organizations also believe the acquisition will strengthen healthcare access throughout northeast Georgia and the region. Wellstar views MLMC as an important healthcare access point uniquely positioned to help connect patients and communities to specialists, advanced treatment options and healthcare resources while allowing patients to continue receiving care close to home.

For team members and clinicians, the transaction represents an investment in the people and relationships that have made MLMC what it is today. Wellstar intends to retain current MLMC team members at the point of transition and anticipates continuity in local operations throughout the process.

Additional information and updates will be shared with team members, clinicians, patients and the community.

Precision treatment advances cancer care with new non-invasive technology

Wellstar MCG Health Medical Center and Wellstar Georgia Cancer Center have begun treating patients using the new Gamma Knife Esprit, the latest state-of-the-art system for non-invasive treatment of neurological and oncologic conditions. The new technology provides patients with the gold standard for non-invasive brain tumor and cancer treatments, underscoring Wellstar and Wellstar Georgia Cancer Center’s dedication to innovation and patient-centered care.

The Gamma Knife Esprit delivers highly precise radiation therapy—to within 0.15 millimeter accuracy—which allows physicians to better treat complex or previously inoperable conditions while preserving surrounding healthy brain matter without the need for traditional surgery. This advanced technology minimizes risk, reduces recovery times and offers hope to patients who may not be candidates for more traditional procedures.

“Bringing the Gamma Knife Esprit to Augusta and the Central Savannah River Area represents a transformative leap in neurosurgical care for our region,” said Dr. Fernando Vale, chair of the Department of Neurosurgery at Wellstar MCG Health and the Medical College of Georgia (MCG) at Augusta University. “With its pinpoint accuracy, we can better treat complex brain conditions while further improving quality of life and reducing patient discomfort.”

Gamma Knife Esprit can target the smallest tumors and lesions with sub-millimeter precision— smaller than the size of a pencil tip—to treat brain lesions, tumors and vascular abnormalities without incisions or general anesthesia. This non-invasive approach results in shorter hospital stays, fewer side effects and faster recovery, making it a powerful resource for patients and their families.

Dr. John Barrett, chair of the Department of Radiation Oncology at MCG, added, “This technology allows us to provide effective, non-invasive treatment options for patients with brain tumors, vascular malformations and other neurological disorders. It’s a significant step forward for our patients and our clinical teams.”

“It is a privilege to serve our community by bringing leading-edge care to the CSRA,” said Ralph Turner, president of Wellstar MCG Health. “This cutting-edge technology strengthens our Neuroscience Center of Excellence and Wellstar Georgia Cancer Center, but most importantly, it ensures that patients from across the region have access to world-class, non-invasive treatment options close to home.”

The addition of the Gamma Knife Esprit further reinforces Wellstar MCG Health’s position as a leader in advanced neurological and cancer care. Through continued investment in technology and partnerships, Wellstar MCG Health remains committed to excellence, innovation and the well-being of every patient we serve.
