No One Deserves Lung Cancer: David’s Story

Mar. 9, 2026

Lung cancer can happen to anyone. For David Knock, early detection through a lung cancer screening gave him a diagnosis in time to treat it. 


In this story, meet David, a husband, father, friend and community advocate. His advice for those facing a lung cancer diagnosis: "mental attitude is a really, really big thing”.

  • Following his doctor’s recommendation for an annual cancer screening, David’s lung cancer was found before he ever had symptoms.
  • Because it was caught early, David began treatment with chemotherapy, radiation, and immunotherapy — guided by a care team that saw him as a person, not a disease.
  • Today, David is speaking out to break the stigma around lung cancer and reminding others not to wait for symptoms before getting screened.

The University of Cincinnati Cancer Center is imagining a better future for the quarter of a million Americans diagnosed with lung cancer each year. Because no one deserves lung cancer—but everyone deserves the best possible chance against it. Explore why we’re different by calling 513-585-UCCC (8222)

A Doctor-Recommended Lung Cancer Screening

In December 2024, what began as a routine lung screening changed everything for David.

Because he has a history of smoking, his primary care doctor Robert Finlay, MD, highly recommended  annual scans. The screening showed a mass in the lower lobe of David’s right lung. Initially, doctors hoped it was an infection. But follow-up scans and a biopsy told a different story.

When David saw the results and read the word “malignancy” three times, he described it simply: “Scary. Very scary.”

It was an emotional day. His wife, Bonnie—his “rock”—and his daughter, Rachel, were by his side. Fear was real. Uncertainty was heavy. But so was faith. David prayed for direction, and over time, he felt a growing sense of comfort.

Taking Back Power

A lung cancer diagnosis can feel like losing control. David remembers that feeling. But when it came time to choose where to receive care, everything changed.

He researched nationally known programs and considered traveling for his care. However, he met with physicians and realized one was available close to his home in West Chester. So, David chose the University of Cincinnati Cancer Center.

“I felt like I had power given back to me,” he shared. David got a clear treatment plan from a whole team of experts working together for him. In return, he got peace of mind.

That choice made all the difference.

Lung Cancer Treatment: More Options

At the time of his diagnosis, David was not a candidate for surgery. Instead, his treatment plan included chemotherapy and radiation: 30 radiation treatments and six rounds of chemotherapy. Today, he continues with immunotherapy, one of the major breakthroughs in modern cancer care.

Immunotherapy works differently from chemotherapy. Instead of directly attacking cancer cells, it helps the body’s immune system recognize and fight cancer more effectively. For many lung cancer patients, it has changed what long-term treatment and survivorship can look like.

Radiation oncologist Emily Daugherty, MD, remembers those early days well. David was anxious, as anyone would be. But they built a relationship quickly—Dr. Daugherty saw David as a person, not a disease—a person who deserved the best.

“We just took it one step at a time,” she said.

Dr. Daugherty specializes in advanced lung radiation techniques that accurately target the tumor while protecting surrounding healthy tissue. She is also leading groundbreaking research on ultra-high-dose-rate, proton “FLASH” radiotherapy—a new treatment option that could reduce long-term side effects. It is just one more way our team is pushing for a better future for people with lung cancer.

But what stands out most in David’s story isn’t just the technology. It’s the human connection.

“I just felt cared for through the whole process,” David said. “I felt a bond with all of the physicians and their staff.”

When he finished radiation, he celebrated the only way he knew how: by bringing donuts to the team who had walked beside him.

Breaking the Stigma of Lung Cancer

Lung cancer can develop for many reasons, including smoking, secondhand smoke, radon exposure, environmental pollutants, and even genetic factors. Often, lung cancer carries a stigma that can add an unnecessary burden of blame.

Dr. Daugherty is clear: “There is no reason to add blame. No matter what caused the cancer, it’s here, and the focus should be on treating it with urgency and compassion. It’s what everyone deserves.”

David echoes that message. Lung cancer can happen to smokers and non-smokers alike.

“Anything can happen,” he says, urging others to prioritize screening and early detection.

The University of Cincinnati Cancer Center recommends lung cancer screenings for adults ages 50 to 80 who have a significant smoking history and currently smoke or have quit within the past 15 years. We offer a low-dose CT scan during the screening process. It's a quick, non-invasive procedure crucial for early detection.

David believes early detection is why he’s here today.

Feeling Seen Matters

Throughout lung cancer treatment, David stays focused on staying positive.

“Mental attitude is a really, really big thing,” he advises others who are beginning their journey.

Dr. Daugherty agrees. While science continues to explore how your mindset can help you heal, one thing is clear: hope matters. Connection matters. Feeling seen matters.

Lung cancer treatment is physical. It’s also deeply personal. The support of family, care teams, and community can make a huge difference.

David wants his story to do one thing above all: save lives. If sharing what he went through encourages even one person to get screened or seek care sooner, it will have been worth it.

Our Mission: A Better Future is What You Deserve

For too long, the nation’s leading cause of cancer death has carried stigma and silence. We believe it’s time to change that.

No one deserves lung cancer. Not the quarter-million Americans diagnosed each year. Not their families. Not David.

But lung cancer patients deserve to be seen. They deserve early detection. They deserve research that improves the status quo. They deserve a team that won’t back down.

At the University of Cincinnati Cancer Center, we believe YOU deserve better. We are taking patient care to the next level through research, innovation, and compassion to make that possible.
