hemorrhoids or anal cancer,Don't mistakenly diagnose hemorrhoids for rectal cancer

    Many people think that ten people have nine hemorrhoids. They don't take hemorrhoids seriously and treat colorectal cancer as hemorrhoids. Such things often happen. This is because the clinical manifestations of rectal cancer and hemorrhoids have many similarities, such as blood in the stool, anal swelling, and increased stool frequency.

    Rectal cancer is easy to confuse hemorrhoids with blood in the stool. When symptoms of blood in the stool occur, most people think about hemorrhoids. Some patients don’t even go to the hospital to see a doctor. They buy topical ointments at the pharmacy and apply them when they feel uncomfortable. In this process, rectal cancer is ignored. They don’t think of seeking medical treatment until the obstruction symptoms such as thinning of the stool appear. It's often already serious. Therefore, patients with blood in the stool, whether they have hemorrhoids or not, should go to the hospital regularly.

    Although the symptoms of rectal cancer are easily confused with hemorrhoids, there are still ways to distinguish them. The first is the difference in blood in the stool. Hemorrhoids in the stool are characterized by bleeding during defecation, the blood is bright red, and stops on their own after defecation. Rectal cancer is blood in the stool, which is mixed with mucus or pus in many cases. This blood color Darker than bleeding from hemorrhoids. Secondly, rectal cancer will have changes in bowel habits, such as thinner stools, increased frequency or alternating constipation and diarrhea. If there is a high degree of suspicion of malignant transformation, pathology should be inserted to make a clear diagnosis. In addition, rectal cancer is often accompanied by other symptoms. Such as abdominal discomfort, bloating or persistent dull pain. Due to tumor consumption, systemic symptoms such as anemia, weakness, weight loss, and low-grade fever may also occur. If it is hemorrhoids, these discomforts are rarely caused.

    Studies have shown that the average misdiagnosis rate of colorectal cancer can reach more than 50%, and the top three misdiagnosed diseases are dysentery, hemorrhoids and enteritis. The three account for 85-90% of the total misdiagnosed diseases. In fact, many malignant tumors that occur in the colon or rectum, if they can be diagnosed and treated early, the treatment effect is very satisfactory.

    Once suspicious symptoms such as blood in the stool and fecal dysfunction occur, you should pay special attention to it. Do not easily conclude that you are suffering from hemorrhoids. Instead, you should consult a specialist in time and do necessary examinations such as digital anus examination, proctoscope, and colonoscopy. Those over the age of 40 who have any of the following manifestations should be classified as high-risk groups: ① Class I relatives with history of colorectal cancer; ② History of cancer or intestinal adenoma or polyps; ③ Positive stool occult blood test; ④ The following five There are two manifestations: mucus blood in the stool, chronic diarrhea, chronic constipation, history of chronic appendicitis, and history of mental trauma. High-risk groups should be checked regularly to be alert to the occurrence of bowel cancer.
