What symptom does bowel cancer have

Symptom 1: right colon cancer. The main clinical symptoms of the right colon are loss of appetite, nausea, vomiting, anemia, fatigue and abdominal pain. The right colon cancer leads to iron deficiency anemia, showing fatigue, fatigue, shortness of breath and other symptoms. The right colon has a large intestinal cavity, and with the growth of the tumor, it will appear abdominal symptoms when it reaches a certain volume. This situation is found that the staging is relatively low when the tumor is diagnosed The main reason for the delay.

Symptom 2: left colon cancer. The intestinal cavity of the left colon is narrower than that of the right colon. The left colon cancer is more likely to cause complete or partial intestinal obstruction. Intestinal obstruction leads to changes in stool habits, such as constipation, bloody stool, diarrhea, abdominal pain, abdominal spasm, abdominal distension, etc. the stool with fresh bleeding indicates that the tumor is located in the end of the left colon or rectum, and the diagnosis of the disease stage is often earlier than that of the right colon cancer.

Symptom 3: rectal cancer. The main clinical symptoms of rectal cancer are hematochezia, change of defecation habits and obstruction. Patients with lower cancer site and hard fecal mass are prone to bleeding caused by fecal friction, mostly bright red or dark red. They are not mixed with formed feces or attached to the surface of fecal column, and are misdiagnosed as hemorrhoid bleeding. The focus stimulation and secondary infection of mass ulcer constantly cause defecation reflex, which is easy to be misdiagnosed as "enteritis" or "bacillary dysentery". The ring growth of cancer leads to the narrowing of intestinal cavity. In the early stage, it is manifested as deformation and thinning of fecal column, and in the late stage, it is manifested as incomplete obstruction.

matters needing attention

After understanding the symptoms of colorectal cancer, we should also pay attention to eating more vegetables rich in dietary fiber, such as celery, leek, cabbage, radish and other green leafy vegetables. Vegetables rich in dietary fiber can stimulate intestinal peristalsis, increase the frequency of defecation, and take away carcinogenic and toxic substances from feces.
