what does a hemorrhoids look like,Blood in the stool needs to be wary of rectal cancer! The relationship between stool bleeding and rectal cancer

    The most common symptom of rectal cancer is blood in the stool. It is often blood on the toilet paper after the stool. At this time, pay special attention and go to the hospital for examination. Because many people have hemorrhoids, the symptoms of hemorrhoids are very similar to this, so if this time comes After the hospital, a doctor will do an anal examination or do a simple anal mirror, which is very valuable for the diagnosis of rectal cancer.

    Similar to hemorrhoids with rectal cancer, it is not uncommon in clinical practice. According to data, the incidence of hemorrhoids in the general population is as high as 45%-50%, and the incidence of colorectal cancer is 2.5%. Among them, patients with rectal cancer account for 40%-50% of colorectal cancer. Hemorrhoids and rectal cancer may occur in the same patient. The clinical manifestations of hemorrhoids are mainly bloody stools and anal discomfort. These signs are very similar to those of rectal cancer. The similarity of symptoms, coupled with the fact that most patients always think that they are unlikely to have cancer, and often ignore the condition. Therefore, friends with blood in the stool should be extra vigilant. If rectal cancer is detected early, the surgical resection rate can reach 100%, and the 5-year survival rate can be above 80%, so early prevention of rectal cancer is the key.

    However, in our lives, many patients often fail to pay attention to the symptoms of blood in the stool, which delays the disease and leads to tragedies. In the past six months or so, the 65-year-old Uncle Chen often had blood in his stools. Uncle Chen always believed that he had caused hemorrhoids again, so he bought some medicines for hemorrhoids. However, after self-treatment such as oral and topical application, he found that he “hemorrhoids” "But it didn't get better, and there were constipation and diarrhea. Recently, Uncle Chen finally couldn't bear it. He went to the hospital for treatment. Unexpectedly, he found out that the "curse" was not hemorrhoids at all, but rectal cancer, and it was in the middle stage.

    "People who misjudge themselves like Uncle Chen account for the majority of patients with rectal cancer, and this rate reaches 50% to 80%." Experts from Fuzhou Anorectal Hospital pointed out that blood in the stool is not necessarily hemorrhoids, it may be rectal cancer. . In the past week, the hospital has detected four patients with rectal cancer. In 2008, more than 150 people were diagnosed with rectal cancer, and the age of onset of rectal cancer has a trend of decreasing. The early diagnosis rate of rectal cancer in young people is very low, and the degree of malignancy is high. Once diagnosed, it is basically late. Not long ago, a 28-year-old young man went to the hospital for an examination. He was in the late stage of rectal cancer and could not be operated on.

    According to experts: "Rectal cancer is most likely to be misdiagnosed as'hemorrhoids', but in fact there is a clear difference between the two, which can be identified by careful observation. Hemorrhoids are manifested as bleeding and bleeding after the stool, while bleeding from rectal tumors is the surface of the stool. There are blood stains; secondly, the amount of bleeding between the two is also very different. Hemorrhoids may bleed almost every time it is difficult to defecate, while the amount of bleeding from rectal cancer is not much, not every time."

    It is understood that the development of rectal cancer is relatively slow, and it takes a year for cancer cells to invade the intestinal tube, and its early symptoms are often relatively hidden. What needs to be reminded is that changes in patients' bowel habits may also be an early sign of rectal cancer. Under normal circumstances, everyone has a certain regularity of bowel movements, either once a day or once every other day. After getting rectal cancer, this regular bowel habit has changed: or constipation, every three or four days; or diarrhea, four or five times a day or more; or alternating constipation and diarrhea; or constipation after defecation. Feeling of unfinished, poor bowel movements. This alternate appearance of constipation and diarrhea is a very important warning signal from rectal cancer.

    According to experts, once symptoms of blood in the stool appear, colonoscopy should be performed to find out the real cause in time to avoid delays. Pay special attention to the five types of high-risk groups: people with a family history of colorectal cancer, people who have found polyps in the colon, people who have recurrent inflammatory bowel disease, people who like a high-fat diet, and people who have had schistosomiasis. If you have stool bleeding, don't just think it's just "hemorrhoids", but go to the hospital for further examination, and take the initiative to prompt the doctor to make a correct diagnosis.
