Colon cancer is commonaly linked to gastrointestinal problems—abdominal cramps, bloating, and stool blood. Not for 57-year-old Karen Kennerley, however, a special education teacher from Lancashire, England. None of these symptoms were experienced by her. All she felt was an abnormal and frequently downplayed symptom: tiredness.Even though everyone around her considered her "fit and healthy," Karen's life was turned on its head when she received a stage 4 colon cancer diagnosis. The sole early warning sign? A sense of fatigue that drained her, one she had initially chalked up to the stress of her job. Today, as she receives treatment and battles for her life, her tale is a grim reminder to others regarding the silent threats of colon cancer.Karen initially went to see her general practitioner (GP) in December 2022 because of ongoing fatigue. Being a hardworking teacher employed in a special educational needs (SEN) school, she felt that her tiredness was only due to extensive working hours. Her GP undertook standard blood tests, and these did not raise any initial alarm. Yet, as a precautionary measure, she was referred for a fecal immunochemical test (FIT) and a colonoscopy in January 2023.In spite of assurances from doctors that she was healthy, Karen's colonoscopy showed a tumor in her large intestine. What was thought to be benign proved to be colon cancer, and she underwent extensive surgery in June 2023 to have the tumor and part of her intestine removed. She then had eight rounds of chemotherapy.After her treatment, Karen anticipated returning to everyday life, convinced that she had won her struggle with cancer. Yet in March 2024, she was admitted to the hospital with suspected appendicitis. The truth was much more terrifying—her cancer had infected her ovaries, advancing to stage 4. She was told that the only treatment offered by the NHS was palliative chemotherapy, to prolong her life, not cure her."I was shattered, from being informed that I was benign, to being informed that I had stage three colon cancer, and then this," Karen explained. "There were just a lot of feelings—devastation, fear, disbelief."Deciding to battle for her life, Karen sought out alternative therapies. She discovered Trans Arterial Chemoembolization (TACE), a focused cancer treatment in Germany. In contrast to conventional chemotherapy, TACE injects cancer-killing medications directly into the tumor, with the possibility of enhancing survival and minimizing side effects.Karen had three cycles of TACE treatments, which cost £35,000 ($44,000 USD). Thankfully, her tumors started to reduce in size. Her finances were drained, however, and she is currently fundraising to pay for additional treatment."Treatment has been going well, but I need more of it. The stress and financial strain are overwhelming. I am unable to work, and my statutory sick pay will soon be gone," she said. "Stage 4 cancer patients feel abandoned. I wish to change this—not only for me, but for others battling this." Importance of Early Detection in Colon CancerKaren's case brings to light an important problem: colon cancer usually comes with mild symptoms that may be ignored. Although frequent symptoms are:Blood in the stoolChanges in bowel habits that persistUnintentional weight lossAbdominal discomfort or bloatingFatigue is a lesser-known but important symptom. In Karen's case, this initial symptom was first explained away as typical work-related fatigue. But it proved to be a sign of a serious underlying illness.Medical professionals emphasize the need for regular screenings, particularly for people over 45, or earlier if there is a family history of colon cancer. A FIT test, which identifies occult blood in stool samples, is a quick and useful screening test.Karen's situation is not rare. Colon cancer is the third most frequent cancer globally, both in men and women. The World Health Organization (WHO) states that early detection is essential in enhancing survival. Despite this, patients are often diagnosed at advanced stages because of imprecise or ignored symptoms.Younger adults have also experienced an increase in colorectal cancer cases in recent years, leading researchers to explore possible causes like diet, lifestyle, and genetics. Public awareness campaigns stress the importance of identifying even non-digestive symptoms, including fatigue, anemia, and unexplained weakness.Aside from her own struggle, Karen wishes to speak out on behalf of improved support mechanisms for stage 4 cancer patients. Most people in her situation feel abandoned by healthcare systems that prioritize curative treatments for early-stage cancers, leaving those with advanced diagnoses with few options."I don't want to fight for myself alone—I want to fight for all those who are going through stage 4 cancer. We deserve better than to be told to get ready for the end," she exclaimed.Karen continues to fundraise to keep up with treatment and raise awareness about listening to your body. "I want people to realize that you don't need to have dramatic symptoms for it to be cancer. If something doesn't feel right, don't ignore it—get checked."Karen Kennerley's case serves as a testament to how cancer may manifest in unexplained manner. She is struggling for survival even as she is fighting to get awareness raised on cancer by appealing to others to place priority on their own health and going for a doctor even at slightest deviations from health.
