The harm of hemangioma to the body depends on its growth site, size and tissue composition. Hemangioma on the body surface: Hemangioma on the body surface can occur in various parts of the human body, but it is more common in the jaw, neck, trunk and limbs, and its color is mostly red, black and green and its shape is irregular or convex, or varicose, or sinuous. If the hemangioma grows on the surface of the body, it is bound to affect the aesthetics and cause harm to the patient’s body and mind, and in serious cases, it may deform the facial features. Angiomas on the body surface can cause hemorrhage if they are struck or compressed by external forces. In the neck and throat, hemangioma may easily break down due to feeding, which may endanger patients’ lives. In functional parts, such as eyes, tongue, fingers, toes, penis, clitoris and joints, it may affect the function of these parts and lead to serious deformation of limbs or affect the growth and development of bones. If the hemangioma is huge, it will seriously endanger the patient’s health no matter what part of the body it grows on. In addition, hemangioma can also become infected, ulcerated, bleeding or even malignant, all of which can seriously endanger the patient’s life. Hemangioma in the body: When the tumor increases in the body, it can compress and push the neighboring organs and cause various symptoms. For example, compression of the lower esophagus, stomach, and duodenum may cause difficulty in swallowing, abdominal distension, abdominal pain, and belching; compression of the liver and biliary tract may cause gallbladder effusion and obstructive jaundice; compression of the portal vein may cause portal hypertension, and compression of the inferior vena cava may cause ascites, and may affect childbirth in pregnant women. Swollen hemangiomas can cause death due to internal pressure or external forces (extrusion, impact, antagonistic movement, etc.) and rupture and hemorrhage of the tumor vessels. In the case of hepatic hemangiomas, the overall metabolic function of the liver can be impaired. The liver is the most active metabolic organ in the body and is involved in the metabolism of almost all substances in the body, which is very important for the maintenance of life. If the metabolic function of the liver is disturbed, the whole body will be greatly affected. In addition, if liver hemangioma is not treated for a long time, it may turn into a malignant tumor and endanger life. The pathologies of hemangioma include: 1) ulceration, bleeding, infection; 2) damage to vital organs; 3) congestive heart failure; 4) limb deformity due to skeletal muscle damage.
