Xiao Wang, an IT worker, suddenly found a lump in the anal opening 4 months ago, bleeding and painful during stool, thinking it was "hemorrhoids", so he went to the pharmacy to buy medicine. However, as time goes by, the symptoms still do not improve, and even new problems appear: there will be mucus and blood flowing out on weekdays, the bowel movement pattern will also change, and there will always be a feeling of incomplete bowel movements. Xiao Wang realized that something was wrong, and came to the Department of Oncology of the Affiliated Hospital of Northwest University and the Third Hospital of Xi'an for medical treatment, and the electronic anorectoscope found a lump about 7cm away from the anus, and further examination confirmed that it was rectal cancer!
These are two very different diseases
Because there is a common feature of "blood in the stool".
Many colorectal cancer patients have relaxed their vigilance
Thus missing the best time for treatment!

What is the difference between hemorrhoids and bowel cancer?
· Q·
【01】The symptoms of blood in the stool are different
Hemorrhoidal blood in the stool: Bright red is often blood on the surface of the stool or blood on toilet paper after wiping.
Colorectal cancer hematochezia: dark red or black, mixed with blood, mucus or pus in the stool, and may not form the stool and directly discharge pus and blood.
【02】Changes in the shape of stool and bowel habits
Hemorrhoids: Does not change bowel habits and properties.
Bowel cancer: There will be changes in bowel movements, such as increased frequency of stool, anal distension, tenesmus, etc., and further growth of the tumor will also lead to difficulty in stool, thinning of stool, rectal obstruction, etc.
[03] Whether you have abdominal pain
Hemorrhoids: There is usually no abdominal pain, basically anal pain.
Bowel cancer: In addition to anal pain, there will be abdominal pain and lower abdominal pain due to intestinal irritation, intestinal obstruction, intestinal perforation, etc.

How to screen for bowel cancer at an early stage?
· Q·
[01] Electronic anorectoscopy
Electronic anorectoscope is mainly used to examine the lesions of the sigmoid colon, rectum and anus, and diagnose and treat by local cleaning of the intestine, which can identify the cause, find the lesion and give intervention treatment, which has the advantages of being fast, convenient and effective.
【02】Digital rectal examination
Digital rectal examination is the simplest and most effective way to detect rectal masses within 7~8cm of the anus.
[03] Tumor markers
Tumor markers are often included in routine physical examination items, but normal tumor markers do not mean that there is no bowel cancer. In fact, only about 40% of colorectal cancer patients have elevated blood CEA or CA199, and most patients with colorectal cancer do not have elevated levels.
The early symptoms of bowel cancer are similar to those of hemorrhoids.
Not even a symptom,
So it's important to have regular checkups!!
