It is important to take blood in the stool seriously. Since blood in the stool is the most common early symptom of internal hemorrhoids, people always treat blood in the stool as an attack of hemorrhoids. Because of this misunderstanding, many people tend to use some suppositories for hemorrhoids on their own when they have blood in their stool, and their symptoms will most likely improve. However, for middle-aged and elderly people, blood in stool may be a danger signal of rectal cancer, which must be alerted enough. The incidence of rectal cancer has been increasing year by year in recent years, but the early symptoms of rectal cancer are not obvious and are most easily ignored by patients and even misdiagnosed by doctors. So, what is the difference between blood in stool of hemorrhoids and rectal cancer? How should we distinguish them in our daily life? Hemorrhoids show bleeding in the anus after defecation, the blood is bright red, not mixed with feces or with blood on the outside of the stool, followed by dripping blood, or even jet-like bleeding, and the bleeding stops on its own after the stool. Internal hemorrhoid bleeding is generally intermittent, and dry stool, fatigue, alcohol consumption, and excessive consumption of irritating food are often triggers for bleeding. In a few patients, severe anemia can occur due to long-term repeated hemorrhoid bleeding. However, blood in stool of rectal cancer is manifested as dark red blood, usually mixed with stool, with blood and mucus in stool. Of course, when blood in stool occurs, it is best to go to the hospital for examination immediately. The doctor only needs to perform a simple rectal finger examination to make a preliminary judgment, which is a necessary examination step for the diagnosis of rectal cancer, and about 80% of rectal cancer patients can be detected through natural rectal finger examination at the time of consultation, and hard and bumpy masses can be palpated. If the doctor at the hospital where Zhuang was seen had been able to tense up the rectal cancer string and do a rectal finger examination, the result would have been different. The actual fact is that you can find a lot of people who are not able to get a good deal on a lot of things. It should also be emphasized that blood in the stool can occur with hemorrhoids, but blood in the stool is not necessarily always caused by hemorrhoids. People generally believe that blood in the stool is due to hemorrhoids, but this is incorrect. Blood in the stool usually occurs during defecation, dripping or jet-like bleeding during and after the stool, and the blood does not mix with the stool. Hemorrhoids are relatively easy to diagnose, but it must be noted that anorectal diseases with symptoms of blood in stool such as rectal adenoma and rectal cancer are often misdiagnosed clinically as internal hemorrhoids. Therefore, it is recommended that patients with blood in the stool must go to anorectal specialist clinics for examination as soon as possible. Even a small rectal examination may determine the type of disease, especially if malignant diseases are excluded, or else delaying the diagnosis and treatment of the disease will certainly leave lifelong regrets for themselves and their loved ones.
