In the world of oncology, there is a recurring tragedy: the symptoms that go unspoken because they are deemed too “private” for polite conversation. Susan Schmidt, a 47-year-old mother of two from Brisbane, Australia, knows this silence all too well. It is a silence she is now determined to break, even as she navigates the reality of an incurable Stage 4 bowel cancer diagnosis.

Her story is a masterclass in the subtlety of a killer—and a haunting reminder that “normal” test results aren’t always a clean bill of health.

“Strange and Subtle”: The Warning Signs

The descent began in mid-2023. As a physiotherapist, Schmidt was used to listening to bodies, yet her own was sending signals she found easy to dismiss. She describes the early onset as “strange” and “subtle,” primarily marked by a level of exhaustion that defied logic.

“I’d drive my daughter 15 minutes to rowing, then have to stop on the way home and nap for 40 minutes,” Schmidt recalled in an interview with the Daily Mail. At the time, she chalked it up to the onset of menopause. It was a logical explanation for a woman in her late 40s, but as she now warns, it was a “warning sign” she brushed off.

The symptoms followed her across the globe. During a trip to France for a friend’s wedding, she experienced constipation for the first time in her life. Surrounded by the indulgences of a European celebration, she rationalized the discomfort. “I blamed the rich food, too much cheese… I didn’t think much of it,” she said.

The Breaking Point

The transition from subtle discomfort to a medical emergency happened back in Brisbane. The pain was no longer a dull ache; it was a crisis. Schmidt found herself on her bathroom floor, enduring eight hours of agonizing pain, vomiting, and diarrhea.

“It was worse than childbirth,” she said, describing a nine-out-of-ten on the pain scale. At one point, she even suspected she had contracted salmonella from her horse. Yet, despite the intensity of the episode, initial medical screenings offered no red flags. Her blood work and stool tests—often the first line of defense in cancer detection—came back normal.

It wasn’t until a colonoscopy in September 2023 that the reality surfaced. The shift in the room was immediate. “When I woke… I wasn’t offered anything to eat or drink,” Schmidt shared. The silence of the nursing staff was broken only when the gastroenterologist arrived to deliver the news: they had found a tumor.

The subsequent CT and MRI scans delivered a further blow. The rectal cancer had already metastasized, spreading to her uterus, pelvic lymph nodes, and right lung. The diagnosis was Stage 4. Incurable.

Fighting the Taboo

Now, Schmidt’s life is measured in cycles of chemotherapy and “wellness windows” between treatments. She plans to resume her heavy clinical regimen after an upcoming overseas trip, with the singular goal of staying well for as long as possible.

But her primary mission has shifted toward advocacy. She believes the “taboo” nature of bowel health is a death sentence for many. “I didn’t talk about my bowel habits, who does?” she remarked. “That’s part of the problem… people don’t raise the alarm early enough.”

In response to her diagnosis, she has launched The Floozie Foundation, an organization dedicated to supporting patients and families within adult cancer wards across Australia. Through her foundation and her active presence on Instagram, she continues to document the grueling reality of her fight, urging others to prioritize intuition over “normal” lab results.

The Journalist’s Takeaway

Susan Schmidt’s case is a stark directive to the public: do not wait for blood in the stool—a symptom she notably never had—to take action.

“Even if your blood work is normal, even if they say it’s stress, diet, or hormones, listen to your instincts,” she insists. It is a powerful plea for self-advocacy in a healthcare system that can sometimes overlook the “subtle” until it is too late.
