As the saying goes, “Nine out of ten men and ten out of ten women have hemorrhoids. This is an exaggeration, but it is enough to show that the incidence of hemorrhoids is very high. The hemorrhoids include internal hemorrhoids and external hemorrhoids, which refer to the varicose veins in the upper and lower rectum on both sides of the anal dentate line (the anatomical structure at the anus). Hemorrhoids generally do not pose a serious health risk to the body, but the presence of hemorrhoids can easily cause misdiagnosis of other diseases. In recent years, I have found several cases of rectal cancer in the work of the “cover” of hemorrhoids, and continue to “grow and grow” until the occurrence of obvious obstructive symptoms before the patient was diagnosed. This reminds me of a neighbor who had hemorrhoids a few years ago and often bought some topical ointment from a pharmacy for self-governance. Later, when the symptoms worsened, he visited our hospital and rectal cancer was found only after rectal finger examination, and it was already at an advanced stage. Therefore, we hope that medical workers, hemorrhoid patients and their families must raise awareness of cancer prevention and health care, and never let hemorrhoids with similar symptoms cover up rectal cancer. The most prominent similar symptom between hemorrhoids and rectal cancer is bloody stool, and often the stool is fresh blood. Especially in the early stage of rectal polyps and rectal cancer (late stage tumor bleeding and necrosis may have pus and blood stool), there is no discomfort other than bloody stool, so it is easy to mistake it for hemorrhoids. In addition, rectal polyps or rectal cancer can easily compress the rectal vein, causing obstruction of rectal venous blood return and secondary hemorrhoids. Under the existing medical conditions, some malignant tumors are not terrible, what is terrible is that they cannot be detected early. Many malignant tumors occurring in the colon or rectum, if they can be diagnosed early and treated early, the effect is very satisfactory. Therefore, patients with blood in the stool, whether they have hemorrhoids or not, should go to the hospital regularly to ask their doctors to do rectal finger examination or rectal and colonoscopy. When you find symptoms such as bloody stools, which are often associated with hemorrhoids, you must consider ruling out other diseases of the intestines. During the treatment of hemorrhoids, if the symptoms do not improve significantly for a long time or if blood in the stool occurs repeatedly, it should also be taken seriously. Don’t let a small hemorrhoid delay the diagnosis of rectal cancer and other diseases. Remember, remember!!!
