What are the symptoms before colorectal cancer becomes cancerous

Many people in life have experienced such symptoms, that is, abdominal discomfort and loss of appetite. Everyone should pay more attention to this situation to avoid hidden dangers of greater diseases and affect the health of the body. So what are the symptoms before colorectal cancer becomes cancerous? Regarding this issue, let's take a closer look at it.

1. Clinical manifestations

The early symptoms of colorectal cancer are only mild loss of appetite, abdominal discomfort, fullness, dull pain, loose stools, diarrhea, etc. The symptoms seen clinically can be roughly described from the following aspects.

1. Blood in the stool. Because the lesion is close to the anus, the blood is often bright red or dark red, and often separated from the stool. Only when the amount of bleeding is large, the stool will be brown-red and jam-like. Among patients with right-sided colon cancer, 36.5% have visible blood in the stool. This is also an early symptom of colorectal cancer.

2. Symptoms of secondary inflammation caused by tumor: frequent mucus in stool, and when the lesion is located in the rectum, symptoms such as tenesmus often occur.

3. Anemia: When chronic blood loss exceeds the body's hematopoietic compensatory function, patients may experience anemia, an early symptom of colorectal cancer. Tumor obstruction: When the tumor grows to a considerable size or infiltrates the intestinal wall muscle layer, it can cause intestinal stenosis, shrinking the intestinal cavity, and obstructing the passage of intestinal contents.

4. Changes in bowel habits and characteristics. Patients with rectal cancer may have more bowel movements, but not much each time, or even no stool at all, only some mucus and blood, and a feeling of incomplete bowel movements. Changes in bowel habits and frequency, as well as constipation or unexplained diarrhea may occur only when the colorectal tumor is relatively large and has erosion, ulcers or infection. If the cancer grows protruding into the rectal cavity, causing the intestinal cavity to be relatively narrow, the stool discharged will often become thinner and deformed, and may be flat, and sometimes some blood will be attached to the deformed stool.

2. Symptoms of meridian blockage

The meridian constitution tumor elimination method found that patients with colorectal cancer have stiffness in the abdomen and back, which is a symptom of meridian blockage. Meridian diagnosis found that there are symptoms of meridian blockage at the Tianshu point of the Stomach Meridian of Foot Yangming, the Daheng point of the Spleen Meridian of Foot Taiyin, and the Kidney Meridian of Foot Shaoyin. The muscle stiffness at the blocked part of the meridian can form lumps of different sizes and shapes. The lumps are different in different parts and different conditions. There will be pain when touching.

Warm reminder: There are many symptoms of colorectal cancer. You can find its existence in life. Sometimes the deterioration of colorectal cancer is because people do not find the symptoms of colorectal cancer in the first time, so they miss the best time to treat colorectal cancer!
