What are the early symptoms of rectal cancer? Beware of the five early symptoms of rectal cancer

The occurrence of rectal cancer is related to lifestyle and eating habits. To prevent rectal cancer, we should focus on the diversification of diet structure, not be partial to one's diet, not be picky about food, and not eat a high-fat, high-protein diet for a long time. In the early stage of rectal cancer, patients may ignore it until the condition worsens. Today, we will introduce the five major symptoms of early rectal cancer.

1. Abdominal pain

Abdominal pain is one of the early symptoms of a small number of patients with rectal cancer. Cancer of the upper rectum or sigmoid colon may cause annular stenosis, intestinal obstruction, and paroxysmal abdominal colic, accompanied by abdominal pain, hyperactive bowel sounds, thinner stools, and reduced anal gas. These symptoms are relieved or disappear to a certain extent after defecation.

2. Blood in the stool

Almost half of the patients with rectal cancer have bloody stools, which often only cover the surface of the stool and are bright red or dark red in color. When cancer only involves the mucosal surface, symptoms such as swelling of the portal of the liver and itching often occur. When cancer invades below the mucosa, bloody stools will occur. This type of bloody stool has a small amount of bleeding, intermittent bleeding, and is mostly bright red or dark red blood.

3. Rectal distension

When the ampulla of the rectum enlarges or invades the surrounding tissues, clinical symptoms such as anal prolapse and insufficient defecation appear. Ampulla cancer is mostly cauliflower-shaped, so secretions mixed with pus and blood flow out of the anus.

4. Significant changes in bowel movement frequency

Changes in bowel habits can also be seen in the early symptoms of rectal cancer. Normal people have regular bowel movements, usually once in the morning. Rectal cancer patients have irregular changes in bowel movement frequency, bowel movement time, and bowel movement frequency. For example, rectal papillary carcinoma has a lot of mucus, frequent diarrhea, and frequent bowel movements. Annular sclerosing carcinoma, which initially has constipation symptoms, has thin stools and diarrhea in the later stages.

5. Mucus in stool

In the swelling of rectal cancer, cauliflower-like tumors and inflammatory lesions of the intestinal mucosa cause a large amount of mucus secretion, forming mucus stools. When the mucus stools are mixed with gas, the stools are foamy. After the cancer lesions, the surrounding infections are combined and a large amount of pus is produced. At this time, it is easy to be misdiagnosed as chronic enteritis and dysentery. When the surface of the cancer is eroded or ulcers are formed, the bleeding is better, the stools are thin, the pus and blood increase, and there is a bloody odor and other symptoms.
