As part of a Community Health series on The Valley Today, host Janet Michael welcomes Dr. Sophia Villanueva, a fellowship-trained colorectal surgeon with Valley Health Surgical Oncology in Winchester. The discussion highlights March as Colon Cancer Awareness Month and covers key topics such as the rise in early-onset colon cancer, the importance of screenings, and preventive measures.
To begin, Dr. Villanueva emphasizes that colon cancer, once considered a disease predominantly affecting older adults, is now increasingly being diagnosed in people younger than 50. "We have seen a rise in early onset of colon cancer. Our guidelines have changed now, so screening starts at age 45," states Dr. Villanueva.
Addressing the potential causes of this alarming trend, Dr. Villanueva explains that while some cases have a family history, the majority are sporadic, tied to environmental factors, diet, and lifestyle. "Obesity, not having enough fiber, eating highly processed meat and food, higher fat content in our diet, increased alcohol intake, and smoking all contribute to higher risks," she notes.
The conversation shifts to the symptoms of colon cancer. Dr. Villanueva highlights that symptoms often include anemia, changes in bowel habits, abdominal discomfort, rectal bleeding, and unexplained weight loss. "It's important not to dismiss these symptoms, even if you're younger than 50," she advises.
When discussing the benefits of early detection, Dr. Villanueva stresses that prompt treatment vastly improves survival rates. "About 90% of colon cancer cases can be treated successfully if caught early," she says. She highlights the importance of routine colonoscopies, describing them as both diagnostic and therapeutic.
Janet and Dr. Villanueva delve into the colonoscopy process, aiming to dispel common fears. They explain that the most uncomfortable part is usually the bowel prep, which involves clearing the intestines. "You get sedated during the procedure, and it's not uncomfortable at all," reassures Dr. Villanueva.
The conversation also covers alternative screening methods like stool tests. However, Dr. Villanueva underscores that colonoscopies remain the gold standard, as they allow for the removal of polyps during the procedure itself.
If diagnosed with colon cancer, the primary treatment is surgery, especially if the cancer hasn’t spread to other organs. Dr. Villanueva points out the advancements in minimally invasive, robotic surgeries that ensure quicker recovery, less pain, and faster return to daily activities.
"Most people can go home within two to three days after surgery," she explains, highlighting the Enhanced Recovery After Surgery (ERAS) protocols that have revolutionized patient outcomes.
The discussion concludes with a fascinating mention of an inflatable colon exhibit at Winchester Medical Center on March 24th, designed to raise awareness and educate the public about colon cancer. Dr. Villanueva encourages everyone to participate, promising an informative and engaging experience. The inflatable colon exhibit is part of Valley Health’s initiative to promote colorectal cancer awareness during National Colorectal Cancer Awareness Month. After its debut at WMC, the exhibit will travel to other Valley Health campuses to continue educating the community. Visitors can walk through the inflatable colon to get a close-up look at healthy colon tissues, tissue with non-malignant colorectal diseases, and tissue with various stages of colorectal cancer.
In wrapping up, Dr. Villanueva emphasizes, "If people get their routine colonoscopy, we can save 40,000 lives every year. It's crucial to spread the word that 45 is the new 50 for colon cancer screenings."
