Every year, National Colorectal (colon) Cancer Awareness Month is observed during the month of March in an effort to raise awareness of the importance for colon cancer screenings.


The recognition offers health care providers the opportunity to educate the general public about a disease that can be preventable, but can sometimes be seen as difficult for patients to discuss with their doctors.



In the spirit of education, one of Augusta University’s experts has provided some insight into the subject of colon cancer.


Dr. Asha Nayak-Kapoor is an associate professor of medicine in the Division of Hematology/Oncology in the Department of Medicine at the Medical College of Georgia at Augusta University. Nayak is certified by the American Board of Internal Medicine in Hematology and Oncology Specialties.



Q: What are the primary risk factors for colon cancer?


“Risk factors for colon cancer include: being overweight or obese, not being physically active, certain types of diets, smoking, alcohol use, being older, a personal history of colorectal polyps or colorectal cancer, a personal history of inflammatory bowel disease, a family history of colorectal cancer or adenomatous polyps, having an inherited syndrome.

Common symptoms of colorectal cancer include: bloody stool or rectal bleeding, an ongoing change in bowel habits (diarrhea, constipation, chance in stool consistency), abdominal pain or cramping, gas or persistent abdominal discomfort, you feel like your bowels are not voiding completely, weakness, fatigue, or unexplained weight loss.”



Q: How can a person protect themselves from the risks of colon cancer?


“Colon cancer is largely preventable if patients undergo screening tests, like a surveillance colonoscopy starting at 45 years or earlier depending on family history.

Many lifestyle-related factors have been linked to colorectal cancer. In fact, the links between diet, weight, and exercise and colorectal cancer risk are some of the strongest for any type of cancer.  Getting to and staying at a healthy weight may help lower your risk. A diet that's high in red meats (such as beef, pork, lamb, or liver) and processed meats (like hot dogs and some luncheon meats) raises your colorectal cancer risk.

Cooking meats at very high temperatures (frying, broiling, or grilling) creates chemicals that might raise your cancer risk. It’s not clear how much this might increase your colorectal cancer risk. Stop smoking. It is best not to drink alcohol.


People with a history of colorectal cancer in a first-degree relative (parent, sibling, or child) are at increased risk. The risk is even higher if that relative was diagnosed with cancer when they were younger than 50, or if more than one first-degree relative is affected.”


Q: It sometimes seems that colon cancer prevention is aimed more towards men compared to women, but cancer.org lists the risks at 1 in 23 (4.3%) for men and 1 in 25 (4.0%) for women. Is there a reason why perhaps a stigma about colon cancer affecting men more has been created?


“According to focus group studies, it can be seen as a taboo topic that is uncomfortable to discuss, and it is not discussed as openly in public as prostate and breast cancer screenings. It can seem embarrassing or humiliating, and can be seen as distasteful dealing with prolonged bowel preparation.”


Nayak is a member of several committees, including Onyx and Bayer Speaker Bureau for Nexavar, MCG Cancer Center Molecular Oncology Programme, and MCG Cancer Center Gastrointestinal Tumor Board Committee.

A Snapshot of the Local Economy: Simon Medcalfe on Growth, Risk, and What Comes Next

At Augusta University’s annual Economic Forecast Breakfast hosted by the James M. Hull College of Business, Simon Medcalfe, PhD, offered a grounded, data-driven look at how the local economy is performing — and what lies ahead. Speaking to business leaders, students and community stakeholders, Medcalfe emphasized the importance of distinguishing real economic growth from inflation-driven gains, noting that while the Augusta region continues to grow, it does so at a measured pace compared to national averages. His presentation framed the local economy as stable and resilient, but not immune to broader forces shaping the U.S. outlook. A key theme of Medcalfe’s remarks was the role of research, innovation and education in sustaining long-term economic health. He pointed to strong gains in research and development across Georgia and highlighted how university-based research directly contributes to regional economic output. According to Medcalfe, investment in knowledge creation remains one of the most reliable drivers of growth, reinforcing the value of higher education institutions as economic anchors. Simon Medcalfe, PhD, is an economist with an emphasis on sports economics, social determinants of health, and the local economy. View his profile At the same time, Medcalfe cautioned against complacency. While regional fundamentals remain solid, he stressed that uncertainty at the national level continues to pose risks. “However, uncertainty abounds in national macroeconomic policy that could negatively impact growth next year,” Medcalfe said, underscoring how unresolved fiscal decisions and policy shifts can ripple down to local economies. Still, his overall outlook balanced realism with optimism. Medcalfe concluded that the Augusta region — and Georgia more broadly — is positioned to weather uncertainty thanks to diversification, investment in early education, and continued research activity. “Overall, Augusta and Georgia are positioned well for economic growth in 2026 with a strong commitment to early childhood education, a diversified labor market and strong research and development,” he said.

From Libraries to Heart Health: Marlo Vernon Takes Cardiovascular Care Into Rural Georgia

Marlo Vernon, PhD, associate professor in the Department of Health Management, Economics, and Policy at Augusta University’s School of Public Health, is leading a creative public health initiative designed to improve cardiovascular monitoring in rural Georgia. Through the university’s Rural Obese At-Risk initiative, Vernon and her team are placing blood pressure monitors in local libraries, allowing residents to check them out just like books. The effort addresses a critical access gap in rural communities where preventive health tools are often limited or difficult to obtain. Vernon’s work focuses on the realities facing communities in the South’s so-called Stroke Belt, where overlapping health conditions significantly elevate cardiovascular risk. View her profile “There are significant chronic disease risk factors in this so-called Stroke Belt. We’ve got high obesity rates. We have family history. We have high rates of diabetes and kidney disease and they all kind of feed into each other to really create this cardiovascular health need in our communities. And women, in general, are just at a higher risk for this,” said Marlo Vernon, PhD. Beyond equipment access, Vernon’s research also examines how people understand and manage their health when traditional care options are limited. The library-based model helps normalize blood pressure monitoring while reducing barriers such as travel distance, cost, and limited clinic availability. It also creates opportunities to study how community-based solutions can improve awareness, engagement, and long-term cardiovascular outcomes. For journalists covering rural health, women’s health, chronic disease prevention, or innovative public-health strategies, Vernon offers grounded, real-world insight into how trusted community spaces can play a vital role in addressing persistent health disparities.

Why Insomnia May Hold the Key to Treating Depression, According to MCG Research

William Vaughn McCall, MD, professor emeritus in the Department of Psychiatry and Health Behavior at the Medical College of Georgia at Augusta University, is leading a new multi-year clinical trial aimed at addressing insomnia and depression together — two conditions that frequently occur side by side. The Assessing Improvements in Mood and Sleep (AIMS) Trial, funded by the National Institutes of Health, is exploring whether treating sleep problems through psychotherapy can also reduce lingering symptoms of depression, particularly in older adults. McCall has served as professor and Case Distinguished Chairman of the Department of Psychiatry and Health Behavior at Augusta University since 2012. His research interests include depression, electroconvulsive therapy, quality of life, insomnia, and suicide. His research has been continuously funded by the National Institute of Mental Health since 1995, and he is the author of more than 400 publications, including more than 180 peer-reviewed journal articles. View his profile McCall’s work builds on decades of research examining how disrupted sleep contributes to mood disorders. While previous studies often focused on medication-based approaches, this trial takes a different direction by testing non-pharmacological therapies that target insomnia itself. The research team, which includes collaborators from multiple universities, is evaluating whether improving sleep quality can meaningfully lower depression symptoms for patients who remain symptomatic despite antidepressant treatment. “Ultimately, the hope is to find other avenues to reduce the risk for depression and depression symptoms,” McCall says. The trial is currently recruiting adults aged 55 and older who are experiencing both insomnia and depression, with options for both in-person and remote participation. For journalists covering mental health, aging, sleep science, or emerging clinical research, McCall is a key expert offering informed perspective on how sleep-focused interventions could reshape the future of depression treatment.
