As the saying goes, "10 men and nine hemorrhoids, 10 and 10 women hemorrhoids." This remark although some exaggeration, but the hemorrhoids suffice to show the incidence rate is very high. Hemorrhoids and Waizhi including hemorrhoids, anal mean, respectively, under the dentate line from top to bottom on both sides of the rectum Cong varicose vein formation of clumps, varicose veins can be due to friction, such as bowel bleeding, or the formation of clumps emerge, the patient is suffering. Hemorrhoids general body does not cause serious health hazards, but the existence of hemorrhoids easily misdiagnosed as other diseases. Recently, the authors found one after another in a few cases of cancer in the hemorrhoids, "sheltering", the "growth expansion" until a clear obstruction symptoms before diagnosis of patients. This reminds me of a few years ago a neighbor suffering from hemorrhoids, often asked me from the hospital to bring some topical ointment. Later, due to increased symptoms to the hospital, found that the cancer, but it is late. I hope that the medical workers, patients and their families hemorrhoids must enhance anti-cancer health awareness, millions of symptoms similar to hemorrhoids Do not cover up the cancer. Hemorrhoids and cancer symptoms similar to the most prominent is the bloody, and often they are the new blood. Especially colorectal polyps and colorectal cancer early (late tumor necrosis bleeding may have Nongxue it), with the exception of blood, then no other discomfort, it is easy to mistakenly thought it was hemorrhoids. In addition colorectal polyps or colorectal cancer easily oppressed vein, the rectum and blocked vein blood returning secondary hemorrhoids. Of the existing medical conditions, some cancer is not terrible, terrible is not early detection. Many in the colon or rectum cancer, if early diagnosis and treatment, the effect is very satisfactory. It is blood in the stool of patients, both have hemorrhoids, should be regularly invited to go to the hospital doctors do rectal or colonoscopy. Found hemorrhoids often have symptoms such as blood, we must consider the exclusion of other gastro-intestinal diseases. Hemorrhoids in the course of treatment, such as no significant improvement in symptoms of long-term or repeated blood in the stool should also be emphasis. Do not let the millions of small hemorrhoids delay the diagnosis of cancer and other diseases.
