What are the dangers of hemorrhoids? Hemorrhoids, like other diseases, are less difficult to treat early and recover quickly. If you miss the best time to treat the disease, it will not only be difficult to treat and slow to recover, but will even cause irreversible damage to your body. On the one hand, if hemorrhoids remain untreated for a long time, they can lead to anal contracture and difficulty in defecation; on the other hand, they can easily lead to anal incontinence by invading the sphincter. In addition, bleeding and inflammation of hemorrhoids often leads to the multiplication of a large number of bacteria, which can cause sepsis when they enter the bloodstream. For female patients, it may lead to gynecological diseases. Furthermore, hemorrhoids can cause pain in the lower back, epiphysis, and posterior femoral area, and can also cause reflex dysfunction of the genitourinary system. Can hemorrhoids develop into cancer? Hemorrhoids are a benign lesion, and so far, there is no evidence to confirm the possibility of hemorrhoids becoming cancerous. However, the early symptoms of rectal cancer are often similar to those of hemorrhoids, which sometimes leads to rectal cancer being misdiagnosed as hemorrhoids, thus delaying treatment. The purpose of the anal finger examination, or even pathological examination, done by the patient during the visit is to distinguish hemorrhoids from rectal cancer. Are hemorrhoids contagious? Infectious diseases are diseases that are caused by viruses and bacteria and spread through air, food and various other contacts. There are three necessary conditions for infectious diseases: infectious source, transmission route, and susceptible people. It is caused by a virus or bacteria. Hemorrhoids are caused by various causes of venous reflux obstruction, stasis and varicose veins in the mucous membrane and muscular layer of the rectum and anus area, not by bacterial or viral infection, so hemorrhoids are not contagious.
