Hemorrhoids and intestinal cancer should not be confused. Besides bloody stool, what are the possible signs of intestinal cancer? 1, defecation habit changes. The appearance of malignant tumor of intestinal cancer can change defecation habits. For example, the frequency of defecation increases to more than 3-4 times a day. When it is obvious, it can even discharge dozens of mucus-like purulent stools every day, or defecate frequently, but the amount of defecation is very small, and it always feels unclean after defecation. This kind of examination refers to an examination method in which the doctor puts on protective gloves and inserts the patient's colon according to the anal orifice to distinguish whether the colon is malignant or not.

2, repeated diarrhea or constipation Due to the stimulation of malignant tumors of intestinal cancer, patients may have diarrhea, severe constipation or the replacement of both. In addition, patients with intestinal cancer should pay attention to the obstruction and extrusion of cancer during defecation, the variability of defecation and the occurrence of ditches. In addition, with the help of some medical examinations, we can also find the early stage of intestinal cancer: fecal occult blood test.

This is also a key technical means to detect early intestinal cancer, which can determine whether there is upper gastrointestinal bleeding, but hemorrhoids and gastritis can also cause upper gastrointestinal bleeding. Therefore, if the stool occult blood test data is positive, the patient should further do rectal digital examination, gastrointestinal endoscopy and other examinations to determine the cause.

Digital rectal examination, also known as "anal examination", refers to an examination method in which a doctor puts on a finger cuff and inserts the anus into the colon of a patient to distinguish whether the colon is malignant or not.

According to rectal digital examination, perianal diseases such as anal ulcer can be diagnosed, and rectal cancer at the bottom can also be preliminarily diagnosed. If the rectal digital examination is abnormal, further colonoscopy can be done.

Colonoscopy and gastrointestinal endoscopy are reasonable technical means to detect early intestinal cancer, which can also detect the existence of intestinal adenoma and immediately block the chance of cystadenoma lesions with minimally invasive technology. People with gastrointestinal diseases and family history of intestinal cancer should have colonoscopy on time. In addition, people with chronic diarrhea and severe constipation and people over 40 years old should also have this check-up regularly.
