Young Woman’s Colon Cancer Diagnosis: A Warning Sign for All Ages

The experience of Katie Davis, a 20-year-old woman who initially dismissed months of sporadic stomach pain as typical college-life discomfort, underscores the increasing – and often overlooked – possibility of colon cancer in younger adults. What began as waves of pain in her abdomen while juggling classes, a job and sorority life ultimately led to a stage 2 colon cancer diagnosis. Her story, recently shared with Business Insider, serves as a crucial reminder to listen to your body and advocate for thorough investigation of persistent symptoms, even if you’re young and seemingly healthy.

Early Symptoms and Initial Misdirection

Davis, then a junior marketing major at Westchester University in Pennsylvania, initially described the pain as fleeting and easily ignored. It would reach and go, lasting only minutes at a time. Although, over three months, the pain intensified, sometimes becoming severe enough to double her over. An initial visit to an urgent care facility while on vacation attributed the discomfort to a possible ovarian cyst, a common issue that often resolves on its own. Ovarian cysts can cause abdominal pain, and the temporary nature of Davis’s symptoms initially aligned with this possibility.

A turning point came when Davis developed chills and vomiting at her parents’ home, prompting a trip to the emergency room. Initial tests revealed inflammation in her colon and the presence of free fluid, raising concerns beyond a simple ovarian cyst. Doctors considered possibilities like Crohn’s disease or ulcerative colitis, but also acknowledged the potential for colon cancer. A colonoscopy was scheduled to investigate further.

Suspicions Confirmed: A Stage 2 Diagnosis

Davis recalls a growing sense of unease after the colonoscopy. She noticed she was placed in a private room, separate from other patients recovering from the procedure. The doctor delivering the results expressed a strong suspicion of cancer, based on his experience. Shortly after, Davis received a confirmed diagnosis of stage 2 colon cancer. Colonoscopies are a key diagnostic tool for colon cancer, allowing doctors to visualize the colon and take biopsies of any suspicious tissue.

The initial shock and confusion were overwhelming. “I didn’t really know what to think or feel,” Davis said. “Definitely just numb and confused at first, like ‘how did I get this?’” This sentiment highlights the unexpected nature of a cancer diagnosis in a young person, where it’s often not the first consideration.

Treatment Challenges and Adaptations

Following surgery to remove the cancerous portion of her colon, Davis began chemotherapy. However, she experienced significant side effects, including extreme fatigue, nausea, and neuropathy – a nerve condition causing a pins-and-needles sensation, particularly with temperature changes. Most alarmingly, she experienced episodes of temporary vision loss. Further research into the chemotherapy drug, oxaliplatin, revealed that vision issues are a known, though uncommon, side effect. Davis also found support and information through organizations like the Colorectal Cancer Alliance (CCA), connecting with others who had experienced similar challenges.

Due to the severity of these side effects, Davis’s chemotherapy regimen was adjusted to a milder, oral medication, extending the treatment duration from three to six months. Despite the challenges, she continued to attend classes whenever possible, determined to maintain a sense of normalcy.

Cancer-Free and a Call for Awareness

Davis completed chemotherapy in June 2025 and was declared cancer-free shortly thereafter. She now undergoes regular blood tests every three months and will have annual colonoscopies to monitor for any recurrence. As a senior, she’s currently interning at a financial advisory firm and planning her post-graduation future. She describes feeling “excited to be normal again” and to resume her life without the constant worry of treatment and side effects.

Looking back, Davis emphasizes the importance of listening to your body and seeking medical attention for persistent symptoms. She notes that her symptoms were unusual for someone her age, and she’s grateful she pursued investigation. “A lot of my doctors said that most people at my age or with my stage wouldn’t really have the symptoms that I had that let me know that something is wrong,” she explained. “I’m glad that I learned to listen to my body.”

Rising Rates of Colon Cancer in Younger Adults

Davis’s story arrives at a time when colon cancer rates are increasing among younger adults. In fact, colon cancer has recently become the leading cause of cancer death in individuals under 50. This shift has prompted a reevaluation of screening guidelines and a greater emphasis on recognizing symptoms in younger populations. While the exact reasons for this increase are still being investigated, potential factors include changes in diet, lifestyle, and the gut microbiome. Research is ongoing to understand the underlying causes of this trend.

What to Do If You Experience Persistent Symptoms

If you are experiencing persistent abdominal pain, changes in bowel habits, rectal bleeding, or unexplained weight loss, it’s crucial to consult a healthcare professional. Don’t dismiss symptoms as simply “stress” or “irritable bowel syndrome” without a thorough evaluation. Be proactive in advocating for your health and seeking a second opinion if you feel your concerns are not being adequately addressed. The CCA and other organizations offer resources and support for individuals facing a colorectal cancer diagnosis or those concerned about their risk.

Ongoing Surveillance and Future Guidance

The medical community is actively working to refine screening guidelines and improve early detection of colon cancer in younger adults. Research is focused on identifying individuals at higher risk and developing more effective screening methods. Regular updates to public health recommendations will be issued as new evidence emerges. Staying informed about the latest guidance from organizations like the American Cancer Society and the U.S. Preventive Services Task Force is essential.
