What are the early symptoms of colorectal cancer?

In the early stage of colorectal cancer, the main symptom is blood in the stool, followed by changes in bowel habits, a feeling of incomplete defecation, tenesmus, etc. In addition, it is very easy to cause obstruction and intestinal irritation symptoms. Colorectal cancer has many prominent clinical manifestations, and patients need to be more careful.

The early symptoms of colorectal cancer are mainly painless blood in the stool. The blood is red or bright red, which is very similar to the symptoms of early internal hemorrhoids. In the later stage, the blood in the stool is mostly dark red, mixed with mucus, blood or pus in the stool.

Secondly, changes in bowel habits are a typical manifestation of mid- to late-stage colorectal cancer. Due to the rectal mass and its secretions, intestinal irritation symptoms may occur, causing patients to experience symptoms such as frequent bowel movements, a feeling of incomplete defecation, and tenesmus. However, the discharge is mostly mucus, pus, and blood. At this time, the shape of the stool also changes, and the stool becomes thinner and thinner.

As the cancer infiltrates around the intestinal wall, the intestinal cavity is narrowed, especially at the junction of the rectum and sigmoid colon. Most of them are narrow hard cancers, which can easily cause obstruction. Due to the long-term chronic consumption of the disease, patients with advanced rectal cancer will have some systemic malignant lesions. In addition, unexplained anemia may occur. Unexplained weight loss, fatigue, and loss of appetite, patients must pay attention to it in time and go to a professional hospital for examination and treatment.
