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.”

Q&A: Breast Cancer Specialist Answers Mammograms and Self Breast Exams Questions

According to the American Cancer Society, 1 in 8 women will get breast cancer in their lifetime. Breast cancer is the second leading cause of cancer death for women. However, when found in its earliest stages, breast cancer can be stopped from spreading, is more treatable and nearly 100% curable. Screening is the best way to find breast cancer early. Let’s talk about mammograms as well as the right way to perform a self breast exam.

Mammograms

When should I start getting mammograms?

Unless you have a new breast problem or need to start screenings earlier because of risk, most guidelines recommend starting screening mammography at age 40.
How often should I get a mammogram?

Guidelines differ somewhat but are consistent that if you are of average risk, you should have them at least every other year.  If you are at increased risk, including having dense breast tissue or a family history of breast cancer,  it is recommended that you get an annual mammography screening and possibly enhanced screenings with MRI, ultrasound or contrast enhanced mammography.

Is getting a mammogram dangerous to my health?

While there is a small radiation exposure with every mammogram, the benefit of early detection of small, curable cancers almost always outweighs that risk of exposure.

Does it hurt to get a mammogram?

Some women do find mammograms uncomfortable.  This is more common when having imaging just before your menstrual period when breast tissue can be swollen and more sensitive.  If you do have extra sensitivity, scheduling the exam after your cycle starts or taking an over-the-counter NSAID pain reliever* a few hours before the exam may minimize the discomfort.  Because positioning of the breast and taking each mammogram image is typically less than 30 seconds, the extent of discomfort during the exam is short-lived.

*NSAIDs are nonsteroidal anti-inflammatory drugs, like ibuprofen (Advil, Motrin), naproxen sodium (Aleve) and aspirin.

Breast self-exam options

What is the correct technique for a breast self-exam?

Any pattern for feeling all of your breast tissue is acceptable. The goal is to make sure you are feeling with varying pressure from your collar bone to cleavage, to the bottom of the breast out to past where your breast meets your chest wall, including your armpit.

How often should I do a breast self-exam?

Self-exams should not be done too often because it can make it difficult to tell if a lump is evolving over time. Think of how hard it is to tell if your appearance changes gradually as you get older because you see yourself every day, compared to more easily seeing changes in someone’s appearance after not seeing them for a long time. Typically, once a month is enough.

Is there a best time to do a breast self-exam?

 It is important to do your breast self-exam in approximately the same time in your cycle rather than a specific interval—especially since not all menstrual cycles are exactly 28 days apart.  Doing the exam at the same place in your cycle will give you consistency in how the tissue should feel in terms of lumpiness, texture and density. 
I encourage my patients to do their exam the day after their cycle starts as a consistent point in their hormonal cycle fluctuations.

What am I actually looking for during a breast self-exam?

Your breast self-exam should be a tool to familiarize yourself with the general “normal texture” of the tissue in each of your breasts so if you detect something that is different, you will be able to identify it as new or changed. 

Can a breast self-exam replace a mammogram?

Self-breast exams cannot replace mammograms because mammograms can detect subtle changes like densities or calcifications that are too small to feel. The goal with screening mammograms is to detect breast cancer before you can feel it because early detection leads to better overall outcomes.

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.
