Colorectal cancer shares some symptoms with a less serious, but much more common disease: irritable bowel syndrome IBS.

So how do you know if your symptoms are cancer, IBS or something else? We talked to David Richards, M. IBS can be hard to diagnose. The main symptoms of IBS are constipation, diarrhea or a combination of the two, accompanied by abdominal pain. Diarrhea, constipation and abdominal pain are all symptoms of colorectal cancer. However, there are additional symptoms that are more concerning. Symptoms lasting more than two weeks should trigger a trip to the doctor.

Based on your age, symptoms and family cancer history, your doctor will decide if you need a diagnostic test like a colonoscopy or CT scan. In addition to colorectal cancer, your doctor will want to rule out inflammatory bowel disease IBD. This family of disorders shares symptoms with IBS and colorectal cancer. Knowing the difference between symptoms of IBS and colon cancer might save someone from a lot of anxiety, and more importantly, give them a longer life to enjoy.

If you are having some unusual changes to your bowel habits, review these differences and then follow up by making an appointment with Digestive Health Services. Unfortunately, there are some symptoms associated with both IBS and colon cancer , and indications that you might have colon cancer often show up later than IBS. That fact makes it all the more important to know the difference. These symptoms could be signs of either condition, which is why all people are advised to complete regular screenings for colon cancer.

We conducted a nationwide cohort study using data from the Danish National Registry of Patients and the Danish Cancer Registry from to We included patients with a first-time hospital contact for IBS and followed them for colorectal cancer. We estimated the expected number of cancers by applying national rates and we computed standardised incidence ratios SIRs by comparing the observed number of colorectal cancers with the expected number.

We stratified the SIRs according to age, gender, and time of follow-up. We found a decreased risk of colorectal cancer in the period 1—10 years after an IBS diagnosis. However, in the first 3 months after an IBS diagnosis, the risk of colon cancer was more than eight-fold increased and the risk of rectal cancer was five-fold increased. These increased risks are likely to be explained by diagnostic confusion because of overlapping symptomatology.

Irritable bowel syndrome IBS is the most common functional disorder of the gastrointestinal tract, characterised by abdominal pain, discomfort, and changes in bowel habits in the absence of known structural or biochemical abnormalities Thompson et al , Although a primary concern of IBS patients is their potential risk of developing colorectal cancer Rey and Talley, , few studies have evaluated the long-term course of IBS Svendsen et al , ; Harvey et al , ; Owens et al , ; Garcia Rodriguez et al , However, after excluding the first year of follow-up, the authors found that the RR was close to that of the general population although no estimates were presented , arguing against a causal association.

As IBS is such a common condition, any associated increased risk of colorectal cancer is a public health concern. We therefore conducted a large nationwide follow-up study to examine the long-term risk of colon cancer among patients with a hospital diagnosis of IBS.

We conducted this nationwide study in Denmark within its population of 5. All Danish residents have a civil registration number, which is a unique personal identifier assigned at birth or upon immigration. This number is included in all public registries and allows unambiguous linkage between registries. The National Health Service provides tax-supported health care for all inhabitants of Denmark, guaranteeing free access to hospitals and general practitioners.

We identified all patients with a hospital contact either admission or contact with a hospital-based outpatient clinic for IBS using the Danish National Registry of Patients DNRP , which has maintained records on all hospital admissions in Denmark since Visits to hospital-based outpatient clinics have been included since DNRP data includes civil registration number and up to 20 diagnoses, classified according to the International Classification of Diseases , eighth revision ICD-8 until the end of and tenth revision ICD thereafter.

We used the following codes to identify IBS: To examine how colonoscopic surveillance affects long-term risk of colorectal cancer, we also identified patients who underwent colonoscopy or flexible sigmoidoscopy within 3 months before or after their first recorded IBS diagnosis, based on Nordic Classification of Surgical Procedures codes KUJF These codes have been included in the DNRP since the end of This is a population-based nationwide registry containing data on incident cases of cancer in Denmark since Storm et al , Data recorded for each individual include civil registration number, method of cancer verification, stage, and residence on the date of cancer diagnosis.

During the — period, all data were initially coded according to ICD-7; subsequently they were recoded using the ICD classification. Patients with a cancer diagnosis before the date of their first IBS diagnosis were not included. The civil registration number encodes age and gender. Published: November 18, Abdominal pain, cramps, and changes in bowel habits are symptoms associated with both colorectal cancer and irritable bowel syndrome.

Colorectal cancer may have additional symptoms of blood in the stool, weight loss, fatigue, and a feeling of incomplete bowel movements. Early detection of colon cancer through screening can be key to better outcomes and survival.
