Wellstar PeopleCare | Richard's Colon Cancer Recovery Journey

How an active retiree beat colon cancer with screening and the support of his Wellstar care team

Man hits a ball on a golf course. Text reads "RichardCare."

Richard Knox isn’t afraid to trust his gut. When the Hiram resident began experiencing abnormal bowel habits, he instantly knew something was off. What happened next involved advocating for his health, finding the right team of specialists to meet his needs and understanding the lifesaving role of a colonoscopy in catching colon cancer early.

Becoming an advocate

Born and raised in Smyrna, Richard spent a fulfilling career with AT&T and called many different cities “home” before his retirement in 1998. He moved back to Georgia and settled in a house by the golf course at Creekside Golf & Country Club.

Richard enjoyed an active lifestyle and managed to stay healthy; in fact, the only time he could remember staying in the hospital was in 1952 when he had his tonsils removed. However, his maternal grandfather died of colon cancer at age 65, so Richard wanted to stay proactive about his colon health, knowing his family history. He had his first routine colonoscopy in his 50s, per his physician’s recommendations—“just trying to be preventative,” he said. (Updated guidelines from the American Cancer Society now recommend that individuals at average risk for colorectal cancer start screening at age 45.)

His third colonoscopy, in 2018, showed no major cause for concern—though a blood test at the time revealed anemia. A few years later, Richard noticed some changes in his bowel habits, including persistent constipation, that made him question his health. He consulted a gastroenterologist, who instructed him to stop taking Tylenol at night to help alleviate his symptoms.

But everything wasn’t fine. “It went on for several months. It wasn’t changing, and it wasn’t getting any better,” said Richard. That’s when he knew it was time to seek a fresh perspective.

Right care, right time

Richard turned to his Wellstar primary care physician, Dr. Roderick Rhyant, whom he and his wife had seen regularly since moving to Hiram. Dr. Rhyant helped coordinate care by referring Richard to a Wellstar specialist, board-certified gastroenterologist Dr. Benjamin Renelus.

During his first appointment with Dr. Renelus, Richard shared the results of his previous colonoscopies and recounted the recent gastrointestinal issues he’d been having. He described Dr. Renelus as someone who “lights up the whole atmosphere” and made him feel at ease discussing what can be a sensitive or difficult topic for many people.

“Richard was by and large very healthy for his age,” Dr. Renelus explained. But something wasn’t quite adding up: “What I saw in his labs was that his hemoglobin started to trend down, [indicating] there may be a GI bleed going on… but he’s not complaining of any abdominal pain. I thought, ‘This may be a tumor.’”

Like Richard, Dr. Renelus trusted his instincts—and when he didn’t feel confident with his patient’s prior colonoscopy report, he recommended a diagnostic colonoscopy. This screening test would allow him to directly examine the inside of the colon and rectum, and take a biopsy of any abnormal colon tissue.

“[Dr. Renelus] just looked at me and said, ‘You know what I’m going to say,’” Richard recalled with a laugh. “And I said, ‘That’s fine, doc. Whatever we’ve got to do. I’ve got to figure out what’s causing this.”

Knowing Richard was fit and healthy enough to undergo the procedure, Dr. Renelus scheduled the colonoscopy at the Outpatient Surgery Center at Wellstar Vinings Health Park. As it turned out, those gut feelings were right: The screening detected obstructive colon cancer.

Collaborative approach

Dr. Renelus shared the diagnosis with Richard, explaining that he had a malignant tumor originating from his colon.

“Breaking bad news, unfortunately, is something that’s not foreign to us as gastroenterologists,” he said. “But the good news is we have all the people in place at Wellstar.”

The physician promptly referred Richard to two of his Wellstar colleagues: Colorectal Surgeon Dr. Anushka Arumugasaamy, who would remove the tumor; and Hematologist/Oncologist Dr. William Forehand, who would oversee Richard’s colon cancer treatment and management.

“He was able to be seen so quickly,” Dr. Renelus said. “And I saw him in the office in between everything that was going on. He was always in good spirits. He trusted the process; he trusted me. There has to be trust on both sides. He did everything that we laid out for him.”

Richard first met with Dr. Arumugasaamy to assess the tumor. She ordered several imaging tests, including a lower abdominal CT scan and an MRI, to help stage Richard’s colon cancer and determine the most effective surgical approach. She then performed surgery to remove the tumor at Wellstar Cobb Medical Center.

The surgery was a success, and Richard experienced minimal pain afterward. Several months later, he saw Dr. Forehand to discuss next steps. Thankfully, Richard’s cancer levels looked good, so Dr. Forehand said they would continue to monitor for any signs of cancer recurrence.

When he returned to Dr. Forehand’s office six months later, the CT scan was “perfectly clear,” said Richard. As a final step, Dr. Renelus performed a post-surgery colonoscopy, where he removed one polyp and confirmed all cancer had been removed.

Richard will continue to see Dr. Forehand annually to ensure he remains cancer-free. “People who develop colon cancer have a 3% risk of developing another cancer within 10 years, so that’s a sizable number considering what they’ve already been through,” explained Dr. Renelus. “Ongoing surveillance is very important.”

Throughout his colon cancer treatment, Richard said he was treated with respect and compassion by every member of his Wellstar care team.

He especially appreciated Dr. Renelus’ expertise and guidance at every step. “He was great,” Richard shared. “The colonoscopy experience with him and the folks at Wellstar Vinings Health Park was fantastic.”

Screening saves lives

As colon cancer continues to rise—it is now the third most common cancer worldwide and ranks second in cancer-related death—regular screenings have become even more important.

“Colonoscopy is unique in the sense that it can prevent colon cancer by removing cancerous polyps,” explained Dr. Renelus. “And if you are diagnosed with colon cancer and we’re able to catch it at an earlier stage, your chance of survival exponentially increases.”

“I want people to trust themselves and if something feels off, go to the doctor,” he continued. “The reality is early detection is best.”

It’s also essential that patients feel comfortable bringing up any concerns with their healthcare providers, as open communication can make a big difference in treatment outcomes. In Richard’s case, Dr. Renelus said that “had he not trusted his gut or not mentioned some of these cue words with me, I don’t know if the colonoscopy would have even been explored with someone like him.”

In sharing his story, Richard hopes he can encourage others to let go of their fears and go get screened.

“If you start noticing something is different—[that] a normal process of your body changes—you need to understand why,” he shared. “That’s what happened to me, and I was fortunate to get my appointment with Dr. Renelus.”

“And if it is colon cancer, don’t give up,” he continued. “It’s very treatable when caught early. The doctors and the facilities are well equipped to do it. So get it taken care of before it gets worse.”

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.
