Introduction
Colorectal cancer may present with hematochezia (passage of bright red blood from the rectum). The presence of hematochezia or purulent bloody stools warrants prompt medical attention. In early-stage colorectal cancer, patients frequently experience such symptoms due to ulceration and necrosis of the colonic mucosa, leading to bleeding. Additionally, early-stage colorectal cancer patients often report abdominal pain of varying severity, resulting from mucosal ulceration and necrosis, secondary infection, and consequent acceleration of intestinal motility.
In real life, if a person maintains poor dietary habits over a prolonged period—combined with other unhealthy behaviors such as smoking and excessive alcohol consumption—they are at significantly increased risk of developing serious complications. Colorectal cancer is one such condition; it is highly dangerous and requires prompt treatment. So, what are the symptoms of colorectal cancer?
What Are the Symptoms of Colorectal Cancer?
Hematochezia (passing blood in the stool) is a common symptom of colorectal cancer. The presence of bloody stools—or stools mixed with pus and blood—should raise immediate concern. Such symptoms frequently appear in the early stages of the disease, resulting from ulceration and necrosis of the colonic mucosa. Early-stage patients often experience abdominal pain of varying severity, caused by mucosal ulceration and necrosis, secondary infection, and consequent acceleration of intestinal motility. Spasms may also occur, contributing further to abdominal discomfort. Additionally, early-stage patients commonly report bloating and dyspepsia, often accompanied by abdominal pain.
Patients with colorectal cancer may develop palpable masses of varying sizes within the colon. In early stages, these masses are typically mobile; however, they become fixed in advanced disease. If secondary infection occurs, marked tenderness upon palpation is often present. As the disease progresses, tumor surface ulceration and bleeding occur, and systemic absorption of toxins leads to systemic toxic manifestations—including anemia, fever, fatigue, and unintentional weight loss. In late-stage disease, hepatic metastases may develop, manifesting as jaundice and ascites.
We recommend that individuals adopt healthy lifestyle and dietary habits and avoid smoking and alcohol consumption. We hope this information proves helpful to you.
