Most colon cancer patients can find symptoms of abdominal mass

Since the early symptoms of colon cancer are not very obvious, many people ignore the occurrence of this disease. Knowing the early symptoms of colon cancer will help you detect the problem and treat it in time. The following is a detailed introduction of the early symptoms of colon cancer by experts.

1. 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, on the other hand, manifests itself as difficulty in defecation, which worsens as the cancer progresses. In addition, if the tumor is located lower, there may also be difficulty in defecation and a feeling of tenesmus. This is one of the early symptoms of colon cancer.

2: The stool contains blood or mucus.

In right-sided colon cancer, the amount of bleeding is small and is fully mixed with feces 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 feces, and in a small number of patients with colon cancer, fresh blood and mucus can be observed in the feces with the naked eye.

3: Abdominal mass.

This is one of the early symptoms of colon cancer. Most patients with colon cancer can find abdominal masses, which are tumors or masses that have infiltrated and adhered to the omentum and surrounding tissues. They are hard and irregular in shape. Some masses can move with the intestines to a certain extent, while in late-stage colon cancer, the masses can be fixed due to the more severe infiltration of the tumor.

4: Gastrointestinal symptoms.

Early symptoms of colon cancer include abdominal distension, discomfort or indigestion-like symptoms, which are very similar to the onset of chronic appendicitis; in the case of left-sided colon cancer, obstruction may occur suddenly, with abdominal cramps, accompanied by abdominal distension, hyperperistalsis, constipation and obstructed gas discharge, or chronic obstructive symptoms such as abdominal distension, constipation, bloody and mucous stool, etc.

Early symptoms of colon cancer are mostly abdominal pain or dull pain, which may be intermittent at first and then become continuous, often located in the right lower abdomen.
