What share of colorectal cancer referrals initially think it’s gastritis?

Question

Accepted Answer

Approximately 40 to 50 per cent of colorectal cancer patients referred initially believe they have gastritis.

About 40 to 50 per cent of patients referred to consultant general and colorectal surgeon Dr Nurhashim Haron initially present with symptoms they attribute to gastritis, rather than a more serious condition like colorectal cancer. This tendency to self-diagnose minor ailments often leads to delayed presentation, with over 70 per cent of patients being diagnosed at late stages three or four.
Misinterpretation of Symptoms Leads to Late Diagnosis
Dr Nurhashim noted that many individuals dismiss symptoms such as upper abdominal burning sensations, indigestion, or stomach pain as mere gastritis or gas, especially if over-the-counter medication provides temporary relief. This misinterpretation means patients often seek medical attention only when their condition has advanced significantly. The core issue, according to experts, lies not in the symptom itself but in how it is perceived and interpreted by the individual.
Colorectal Cancer Incidence and Age Shift
Colorectal cancer is the second most common cancer in Malaysia. National cancer registry data indicates an increasing trend in incidence rates for both men and women. Worryingly, the age profile of affected patients is also shifting downwards, with cases now being seen in individuals in their 40s and even younger, a departure from previous trends where the majority of patients were between 55 and 65 years old.
Red Flags Often Ignored
Changes in bowel habits, such as altered frequency, thinner stools, or changes in consistency, are among the earliest warning signs of intestinal disease. More alarming signs include blood or mucus in stools, persistent diarrhoea or constipation, and a feeling of incomplete evacuation. However, these symptoms are frequently mistaken for gastritis, stress, or dietary issues, leading to further delays in seeking professional medical evaluation.
Impact of Delayed Treatment
The consequences of delayed diagnosis are significant. When colorectal cancer is detected at late stages, treatment becomes more complex, often involving surgery, chemotherapy, and radiotherapy. Early detection, conversely, can mean that surgery alone is sufficient, leading to a higher chance of recovery and potentially eliminating the need for additional treatments like chemotherapy.
