The rectum is the "terminal" of the digestive tract. Food is digested and absorbed from the mouth through digestive organs such as the esophagus and stomach, and then forms feces in the large intestine and is excreted regularly. Therefore, the early symptoms of bowel cancer are mostly manifested as changes in the regularity and characteristics of defecation.
① Obvious changes in bowel habits, diarrhea or constipation, or diarrhea and constipation alternately;
② Stool with blood, mucus, pus and blood in the stool, and feeling of incomplete defecation;
③ The stool shape changes, becomes thinner, flattened or grooved;
④ Discomfort such as abdominal pain and bloating, loss of appetite;
⑤ There is a lump in the anus or abdomen;
⑥ Significant weight loss recently, anemia of unknown cause;
⑦ Past history of repeated hemorrhoids, multiple familial polyps, etc.
Regardless of the age group, blood in the stool, etc., do not rush to the conclusion of "hemorrhoids", you should be more careful and be sure to exclude rectal cancer first. Don't let small hemorrhoids delay the early diagnosis of rectal cancer. Early rectal cancer has a great chance of being cured, but when it comes to the advanced stage, no matter how smart doctors and advanced medical technology are, it’s not enough.
