Everyone will have some mole on their body to some extent. But have you ever heard of people with spider moles on their bodies? Recently, there have been media reports that a man in Hunan province developed a rash that spread like a "spider web" and eventually discovered liver cancer. Many netizens can't help but feel a bit "discolored" when they smell moles, so they quickly observe the moles on their bodies. Is spider mole a sign of liver cancer? What should I do if I have spider moles? Experts point out that there is a certain correlation between spider nevi and liver cancer, but the presence of spider nevi does not necessarily mean liver cancer. According to reports, Mr. Li from Hunan has developed a rash on his body since last spring. He thought it was just a skin allergy and bought some anti allergic ointment to apply on his own. But it hasn't been cured by this Spring Festival yet, and the rash is spreading like a spider web. What surprised him even more was that he only discovered during a recent physical examination that liver cancer was causing the problem. Spider nevi is a relatively special skin manifestation. The shape of spider nevi, as its name suggests, has a central point around the nevus body, surrounded by radiating small blood vessel branches. Overall, it looks like a small spider lying on the skin, usually appearing on the face, neck, upper chest, and upper limbs. Sun Weiwei, Deputy Director of the Fourth Department of Hepatology at Tangshan Hospital of Nanjing Second Hospital, pointed out that spider nevi are mainly divided into two types: physiological and pathological. There is a certain correlation between spider nevi and liver cancer, but having spider nevi does not necessarily mean having liver cancer. Sun Weiwei introduced that physiological spider nevi are more common in adolescents and pregnant women during puberty. Spider nevi mainly appear due to changes in estrogen levels in the body, and can gradually disappear after a period of time. Pathological spider nevi mainly appear in people with alcoholic hepatitis, fatty liver, viral hepatitis, liver cirrhosis and other diseases. These patients have impaired liver function and reduced ability to inactivate estrogen, leading to the appearance of spider nevi. "The condition of spider nevi can also reflect the quality of liver function to a certain extent," Qiu Jie, director of the First Department of the Cancer and Vascular Disease Intervention Center at Nanjing Second Hospital, told reporters. When the liver function is poor, spider nevi are prone to growing larger and turning red; When liver function improves, spider nevi will become smaller and lighter. In addition, certain endocrine disorders may also cause spider nevi. Experts say that spider moles only indicate possible liver dysfunction or hormonal changes, but cannot be used to diagnose liver cancer solely based on spider moles. This also means that to determine whether there is liver cancer, a comprehensive judgment needs to be made based on symptoms, liver function tests, tumor marker detection, imaging examinations, and even pathological examinations. The reporter noticed that netizens still have a question: how to determine whether a red mole is a spider mole? Regarding this, Sun Weiwei explained that by forcefully pressing on the center red dot of the mole, it can be seen that the surrounding capillaries have faded. If the pressure is removed, the color of the mole can be restored, which is known as a spider mole. Experts remind that once spider nevi appear, it is necessary to go to a formal medical institution for examination. If it is due to physiological reasons, special treatment is usually not required; If it is caused by a disease, actively treating the primary disease is crucial. (Lai Xin She)
