1 Early symptoms of rectal cancer

1. Abdominal distension and abdominal pain

The reason is due to intestinal dysfunction or intestinal obstruction. The location is mostly concentrated in the middle and lower abdomen, and is mostly dull or distended pain, with a tendency to gradually worsen. 2. Blood in the stool

Because the lesion is close to the anus, the blood color is mostly bright red or dark red, and the blood is often separated from the stool. Only when the amount of bleeding is large, the stool will be brown-red and jam-like. 3. Anemia

When long-term chronic blood loss exceeds the body’s hematopoietic compensatory function, the patient may develop anemia, an early symptom of colorectal cancer. Tumor obstruction, when the tumor grows to a considerable size or infiltrates the muscular layer of the intestinal wall, can cause intestinal stenosis, the intestinal cavity becomes smaller, and the passage of intestinal contents is blocked. 4. Changes in bowel habits and characteristics

Patients with rectal cancer may have more bowel movements, but each bowel movement is not much, or even no stool at all. They only discharge some mucus and blood, and have a feeling of endless bowel movements.

Changes in bowel habits and frequency, as well as constipation or unexplained diarrhea, may occur only when the large intestinal tumor is relatively large and has erosion, ulcers or infection. If the cancer protrudes and grows into the rectal cavity, causing the intestinal cavity to be relatively narrow, the stool excreted is often thin, deformed, and may be flat. Sometimes the deformed stool has some blood streaks attached to it.
