However, the exact mechanism of the relationship between diet structure and the occurrence of rectal cancer is not fully understood, and it is generally believed that it may be related to bacterial breakdown products, metabolites of animal fat, and due to the low fiber diet, the intestinal peristalsis is slow, and the intestinal toxin absorption is increased.

2. Genetic factors.

About 5-10% of rectal cancer patients have a significant family history of cancer, which is manifested by: (1) at least one of them was diagnosed with rectal cancer before the age of 50. (2) Three or more family members have rectal cancer, and more than two of them are of the same generation.

What are the early symptoms of rectal cancer?

There are several main symptoms of rectal cancer:

Hematochezia, blood in the stool is often the first symptom of rectal cancer patients, and the early amount is very small, usually manifested as fresh blood marks attached to one side of the stool. If the stool stays in the sigmoid colon for a longer period of time, the color of the blood in the stool will become darker, and the final stool will be purple or blackish-purple, which will appear later than the blood in the stool and may not be the first symptom of the patient. Sometimes it stays in the body for a long time due to the small amount of blood and is not visible to the naked eye, but it is positive when the fecal occult blood test is performed.

Blood in the stool of bowel cancer should be distinguished from blood in the stool caused by diseases such as hemorrhoids, anal fissures, bacillary dysentery, enteritis, intestinal polyps, and ulcer perforation.

Change in bowel habits.

These include changes in the timing and frequency of stools, as well as constipation or unexplained diarrhea. Patients with rectal cancer may have more frequent stools, but each time they have not had much stool, or even no stool at all, but only some mucus and blood, and there is a feeling that the bowel movements are inexhaustible. Some patients may have diarrhea after constipation, or they may only start dry stools with thinning at the ends, or they may alternate constipation with diarrhea.

Diarrhea increases the number of bowel movements per day, which can be mucus blood, mucus pus or blood stools, or tie stool, and may be accompanied by tenesmus, which should be distinguished from dysentery.

Some patients present with vague abdominal pain as the first or prominent symptom, while others present with typical incomplete intestinal obstructive abdominal pain, i.e., the pain is paroxysmal and accompanied by abdominal distention.

The early symptoms of rectal cancer are mainly blood in the stool and changes in stool quality, a feeling of incomplete bowel movements, and progressive thinning of the stool. Usually eat less greasy food, high-fat, high-calorie food, and strengthen physical exercise.

There is a pressure mark in the middle of the stool, and there is blood during it, but hemorrhoids have similar symptoms.

The early symptoms of rectal cancer are non-specific, and most of them have no obvious symptoms, and when patients have abdominal pain, abdominal distention, weight loss, and abdominal mass, the tumor is mostly at an advanced stage. The early symptoms of rectal cancer include: 1. Change in bowel habits without obvious reasons, increasing or decreasing the frequency of bowel movements; 2. If there is blood in the stool or mucus and blood in the stool, hemorrhoids are excluded and exist for a long time, colonoscopy should be carried out in time, early detection and early detection will improve the effect.
