Late-stage symptoms of left-sided intestinal cancer

Left-sided intestinal cancer: The intestinal cavity is narrower in left-sided intestinal cancer, and the stool in the intestine becomes dry and hard due to the absorption of water. Most left-sided intestinal cancers are invasive, often causing annular stenosis, so the clinical manifestations are mainly acute and chronic intestinal obstruction. The tumor is small in size, with less ulceration and bleeding, and no toxin absorption, so anemia, weight loss, cachexia and other phenomena are rare, and the tumor is not easy to palpate.

Left-sided intestinal cancer symptoms:

1. Abdominal colic is the main manifestation of intestinal obstruction associated with cancer. Obstruction may occur suddenly, with abdominal colic, accompanied by abdominal distension, hyperperistalsis, constipation and obstructed gas discharge. Chronic obstruction manifests as abdominal distension, paroxysmal abdominal pain, hyperactive bowel sounds, constipation, blood and mucus in stool. Partial intestinal obstruction sometimes lasts for several months before turning into complete intestinal obstruction.

2. Difficulty in defecation. Half of the patients have this symptom, and as the disease progresses, constipation becomes more severe. If the tumor is located lower, there may also be difficulty in defecation and a feeling of tenesmus.

3. Blood or mucus in the stool. As the stool in the left colon gradually takes shape, blood and mucus are not mixed with the stool. In about 25% of patients, blood and mucus can be seen in the stool by naked eye.
