I'm a Gastroenterologist. These 3 Colon Cancer Symptoms Fool Most People
Dr. Derek Ebner told Newsweek not all warning signs of colorectal cancer begin where you'd expect.
Few realize that colon cancer can manifest through lesser-known symptoms, often leading individuals to dismiss them as everyday occurrences. As the incidence of colorectal cancer rises among younger adults, medical professionals are emphasizing the importance of vigilance regarding changes in one's health. According to projections from the American Cancer Society, approximately 108,860 new instances of colon cancer will be diagnosed in the United States by 2026.
Dr. Derek Ebner, a gastroenterologist at the Mayo Clinic specializing in colorectal cancer prevention, has identified three symptoms that are often overlooked as warning signs of the disease. Dizziness, weakness, and persistent fatigue, while seemingly unrelated to the digestive system, can indicate iron deficiency anemia caused by the cancer.
Colorectal cancers may bleed slowly, and the resulting blood loss might not be visible in the stool, leading to feelings of exhaustion after routine activities and a general sense of weakness or light-headedness.
Another symptom that many individuals might not connect to colon cancer is shortness of breath. This can occur when the body lacks sufficient iron, often due to blood loss, resulting in diminished hemoglobin production. As oxygen levels decline, individuals may experience fatigue, weakness, and breathlessness, particularly during physical exertion. Due to the gradual development of these symptoms, they are frequently attributed to other factors before the underlying cause is determined.
Additionally, colorectal cancer can affect normal bowel function in ways that may be mistaken for common digestive issues. While diarrhea and blood in the stool are well-known symptoms, some individuals experience a persistent sensation of needing to have a bowel movement even after using the restroom. This sensation, medically referred to as tenesmus or incomplete evacuation, can be mistaken for constipation, hemorrhoids, or other benign bowel problems.
It is crucial to understand that experiencing one of these symptoms does not necessarily indicate the presence of colon cancer. Various factors can cause dizziness, shortness of breath, and changes in bowel habits, many of which are far more common and less severe. However, if any new symptom persists, intensifies, or cannot be easily attributed to other causes, it is advisable to consult a healthcare professional.
Early detection remains one of the most effective strategies in treating colorectal cancer, and identifying potential warning signs at an early stage can help ensure timely access to necessary care.
