What are the early symptoms of colon cancer

Colon cancer is a common digestive tract malignancy that occurs in the colon, ranking third among gastrointestinal tumors. Since the early symptoms of colon cancer are mostly mild or not obvious, they are often ignored by patients and are easily misdiagnosed. In order to better prevent colon cancer, it is extremely important to know the early symptoms of colon cancer. So what are the early symptoms of colon cancer? Do you know what the early symptoms of colon cancer are?

The early symptoms of colon cancer are mainly manifested in:

1. Digestive tract symptoms: manifested as abdominal distension, discomfort or indigestion-like symptoms. In the case of right-sided colon cancer, most cases are abdominal pain or dull pain. It may be intermittent at first, then become continuous, often located in the right lower abdomen, much like a chronic appendicitis attack; in the case of left-sided colon cancer, most cases are obstruction, which may occur suddenly, with abdominal cramps, accompanied by abdominal distension, hyperperistalsis, constipation and obstructed gas discharge, or chronic obstructive symptoms such as abdominal distension, paroxysmal abdominal pain, hyperactive bowel sounds, constipation, bloody and mucous stool, etc.

2. Changes in bowel habits: Right-sided colon cancer manifests itself as early thin stools with pus and blood, and increased bowel movements. When the tumor continues to grow and affects the passage of stool, alternating diarrhea and constipation may occur. Left-sided colon cancer manifests itself as difficulty in defecation, which worsens with the progression of the disease. In addition, if the tumor is located lower, there may also be difficulty in defecation and a feeling of tenesmus.

3. Blood or mucus in stool: In right-sided colon cancer, the amount of bleeding is small and is fully mixed with stool due to the peristalsis of the colon, making it difficult to see with the naked eye, but the occult blood test is often positive. In left-sided colon cancer, the bleeding and mucus are not mixed with stool, and about 1/4 of patients can observe blood and mucus in their stool with the naked eye.
