Oncology Certified Nurse (OCN) Nursing Practice Test

Which of the following is an early symptom of colorectal cancer?

1. Weight loss

2. Change in bowel habits

3. Chest pain

4. Fatigue

The correct answer is: Change in bowel habits

Changes in bowel habits are considered an early symptom of colorectal cancer due to their direct association with alterations in the function of the gastrointestinal tract, which can be influenced by the presence of tumors or growths. This can manifest as diarrhea or constipation, a change in the frequency of bowel movements, or narrowing of the stool. Such changes often prompt individuals to seek medical attention, thereby facilitating earlier detection of potential malignancies. Weight loss, while it can occur with colorectal cancer, is more commonly seen as a later symptom when the disease has progressed or when significant factors such as appetite loss or increased metabolic demand are present. Chest pain is typically not associated with colorectal cancer, as it is more relevant to cardiac or pulmonary issues. Fatigue can be a symptom of many conditions, including cancer, but it is usually more pronounced in later stages or when significant systemic effects, like anemia, are present. Changes in bowel habits stand out as a significant early indicator prompting further investigation for colorectal cancer.
