When a sharp, stabbing stomach pain hit 39-year-old Krystal Maeyke, she attributed it to an allergy or working too hard as a mom. Active, healthy, and fit, the mother of one did not think of herself as vulnerable to cancer—until symptoms could no longer be denied.Three months after that, Maeyke was diagnosed with stage 4 metastatic bowel cancer, a fact that put her world into disarray and is now a warning to young adults around the world: cancer doesn't care how fit or healthy you look or feel. Even though she was "super healthy and fit," Krystal's experience is a wake-up call that cancer doesn't discriminate on the basis of age, fitness, or family history. Her experience, honestly filmed on TikTok, is now prompting tens of thousands to see and respond to the tricky, much-misunderstood signs of bowel cancer.Krystal's nightmare started with what she thought were harmless symptoms—sharp, stabbing pains in the lower abdomen. Similar to many, she credited them to an assumed food allergy or irritable bowel syndrome (IBS), particularly given that she was otherwise healthy and had no history of cancer in her family. For three months, she dismissed the discomfort as a result of the demands of motherhood and an active lifestyle. But the symptoms didn't end there. Krystal remembers having:Recurring, inexplicable night sweats: So bad that she would wake up soaked, having to change clothes and sheets several times throughout the night.Chronic fatigue: She was exhausted all day, all the time, but wrote it off as the unavoidable exhaustion of being a working mom.Loss of appetite and abnormal bowel habits: She experienced changes in digestion, but attributed them to diet or stress.General malaise: A sense of illness that she couldn't put her finger on.These signs, she later discovered, were the classic prodrome of bowel cancer. But since they were mild, non-specific, and readily explainable by less serious causes, Krystal—like many others—dismissed them until the pain was excruciating."I was experiencing stabbing pains, very fatigued, night sweats, loss of appetite, spastic bowel movements, and just off in general," she explained in an open TikTok video chronicling her diagnosis. Like many others, she wrote it off as stress, a busy life, and maybe food intolerance.She had never thought that these symptoms might be indicative of something potentially deadly.Some evenings I would wake up sweating and need to change my clothes and bedding. But it was summer, and I had the air conditioner on, so I figured the room wasn't cold enough.The turning point came when Krystal’s pain reached an intensity she could no longer manage. Living in the remote Australian desert town of Yulara, she was airlifted 280 miles by the Royal Flying Doctors Service to Alice Springs Hospital. There, a battery of tests revealed the unthinkable: stage four metastatic bowel cancer. The cancer had spread beyond her bowel to her abdomen, liver, and ovaries.Krystal remembers the incident clearly, "I was awoken later that night by a doctor whose words I will never forget. 'Krystal, I've got bad news… You have cancer.' The gravity of those words, coupled with my question of 'How do you know?' and the doctor's reply, 'It's everywhere,' shook me to my core."What is Advanced Bowel Cancer?Stage four, or metastatic, colorectal cancer implies the disease has invaded distant organs. The Cleveland Clinic describes this as the most advanced and hardest-to-treat stage. Krystal's case is not unusual: many patients, particularly younger ones, are diagnosed late because early signs are indistinct or mistaken for less severe conditions.Krystal's case highlights an important reality: bowel cancer can develop and spread viciously, even for those who look reasonably healthy. She experienced every stabbing pain as the tumour developed, almost clogging her bowels, and subsequently noticed a lump she was aware of was not an innocent lymph node, but a tumour.I was awakened by a doctor whose words I'll never forget," she said. "'Krystal, I've got bad news… You have cancer.' When I asked him how he knew, he said, 'It's everywhere.'Stage 4 bowel cancer, or metastatic colorectal cancer, is when the cancer has spread to other parts of the body away from the colon or rectum—usually to the liver, lungs, or ovaries. In Krystal's situation, tumors were located throughout her abdomen, liver, ovaries, and bowel. She suspects the constant stabbing pains were because tumors were compressing the important organs and nerves."I could feel each stabbing pain," she said. "The tumor was halfways blocking my bowels. I could feel the lump, which they informed me could be merely a lymph node—it was the tumor. And then I could feel it reach my ovaries."Why Are Younger People at Risk?A recent study by Cancer Research UK and international studies have pointed to a concerning trend: bowel cancer diagnoses are increasing among individuals under the age of 50. For 27 of 50 countries, cases of early-onset have grown, with young adults diagnosed 23% more in some age brackets. The recent passing of social media personality Tanner Martin at the age of 30 has further focused attention on this concerning trend.What is perhaps most shocking about Maeyke's story is how many of her symptoms are so typical, non-threatening complaints—tiredness, irregular bowel movements, night sweats that occur with the rise in temperature. With no known family history of cancer, exercising regularly and having a well-balanced diet, she had every reason to assume she was healthy.But as Krystal's case highlights, bowel cancer is striking younger and younger adults, and the initial symptoms are usually not recognized or misdiagnosed.Krystal's case is an impassioned plea to act. If you have persistent, unexplained symptoms—most importantly, abdominal pain, night sweats, or alteration in bowel habits—do not brush them aside. Seek advice from a doctor and push for extensive testing if symptoms remain.Early diagnosis is key: although only slightly more than half of bowel cancer sufferers live 10 years after diagnosis, prognosis is so much better if the disease is diagnosed early. Screening and knowing the symptoms can help save lives.In the United States, the second most common cause of cancer mortality, colorectal cancer, has seen its diagnoses in people below 50 years surge dramatically over the past few years. Scientists are yet to figure out why—citing processed food, inactive lifestyles, environmental pollutants, and even microplastic exposure as probable culprits.The passing of 30-year-old influencer Tanner Martin from colon cancer last year pushed the issue further to the forefront, prompting discussions around early screening and education.Recognising Symptoms of Bowel CancerThe symptoms of bowel cancer may be challenging to identify in its early stages, Cancer Research UK and the Cleveland Clinic say. Some common symptoms include:Rectal bleeding or blood in the stoolChanges in bowel movements (constipation or diarrhea)Fatigue or shortness of breathAbdominal pain or bloatingUnexplained weight lossA lump in the abdomenYet, many patients show no symptoms until the cancer has already progressed—underscoring the need for vigilance and proactive screening.Since her diagnosis, Krystal has undergone multiple rounds of chemotherapy and shares her cancer journey with over 50,000 TikTok followers, aiming to raise awareness and offer support to others facing similar battles.One of her biggest worries, she says, isn't the disease itself—but the psychological cost on her young son, Maison."He longs for my warmth, my guidance, and my love—a love that cancer is stealing away," she wrote in a heartbreaking post.But she's still dedicated to raising awareness. Her tip: "Take symptoms seriously. Night sweats, pain, fatigue—don't ignore them. Trust your instincts. Early detection might just save your life."
