The dangers of hemangioma
        The harm of hemangioma depends on its growth location, size and tissue composition. If hemangioma grows on the face, it will inevitably affect the beauty. In severe cases, facial features can be deformed; it is easy to cause ulceration in the neck and throat due to eating, which can endanger the life of the patient; in functional areas, such as eyeballs, tongue, fingers, etc. The toes, penis, clitoris, and joints can affect the function of these parts. If the hemangioma is huge, no matter where it grows, it will seriously endanger the health of the patient. In addition, the hemangioma can also cause infection, ulcers, bleeding and even malignant transformation, which will seriously endanger the life of the patient. Therefore, hemangiomas must be treated.

Precaution
        1. To prevent hemangioma, first do not eat drugs and foods containing estrogen during pregnancy. Some scholars believe that the increased content of estrogen in the human body is one of the causes of hemangioma.
        2. To prevent hemangioma, it is best to consider not breastfeeding the newborn baby. This is also a consideration for avoiding the increase of estrogen in the baby's body.
        3. To prevent hemangioma, mothers must do the work during pregnancy, and women during pregnancy should eat less spicy and cold and other irritating foods, so as not to stimulate the embryo and affect the normal development of the embryo. Studies have found that stimulating food can stimulate the development of embryos, and may cause abnormal or deformed development of infant blood vessels and other tissues.
        4. To prevent hemangioma, also pay attention to the balanced nutrition of infants. The balanced nutrition of infants is conducive to enhancing the baby's resistance and immunity, so that the baby is less likely to suffer from diseases.

Treatment programs
        The treatment of vascular or vascular malformations should be determined according to factors such as the type, location, and age of the patient. The current treatment methods include shell removal, radiation therapy, hormone therapy, hypothermia therapy, laser therapy, sclerotherapy, etc. Comprehensive therapy is generally used. Hemangiomas in infants and young children should be observed, and if they develop rapidly, certain interventions should be given in time.
        Hemangioma is composed of a large number of proliferating blood vessels and is a common soft tissue tumor. Blood vessels and lymphatic vessels belong to the same source. In the early embryonic stage, the primitive vessel is a tube composed solely of endothelial cells, which form a dense network in the interstitium. Later, with the development of various organs, the original vascular network gradually differentiated into many vascular plexus and lymphatic plexus connected with the organ. Although the final formation process of the peripheral circulatory system is not well understood, according to the experimental results, it is certain that it is closely related to the flow and pressure in the vessel. In the primitive stage, there is no difference in the structure of arteries, veins, and lymphatic vessels. Only in the future, supply vessels (arteries), draining vessels (veins) and lymphatic vessels are generated. The muscle fibers in the middle layer of the blood vessel and the pedicle tissue of the adventitia all develop from the interstitium surrounding the primitive endothelial cells. In the process of differentiation, any abnormality of the above-mentioned tissues can form tumors, and hemangioma or (and) lymphangioma occurs. During the embryonic development of blood vessels, they can be distributed roughly, including the plexus stage, the reticular stage and the stem stage. Stages, if obstacles or abnormalities occur during normal development at a certain stage, abnormalities in the normal developmental morphology of that stage can occur.
Treatment methods: ① surgical resection; ② cryotherapy; ③ radiation and isotope therapy; ④ sclerotherapy; ⑤ laser treatment; ⑥ hemangioma copper needle therapy.
        1. Surgical treatment: the use of surgical methods to remove the diseased tissue to achieve the purpose of treatment. It is effective for independent and smaller lesions. Under normal circumstances, the diseased area is rich in blood vessels and has a large blood volume. The blood loss during the operation is extremely large, which often causes severe hemorrhagic shock. During the operation, a large amount of whole blood is required for transfusion, which is difficult and dangerous. At the same time, because the blood after hemorrhage is often not completely removed and the operation is forced to terminate, the recurrence rate is very high. Surgical removal of part of the tumor body sequelae local deformity, loss and dysfunction. Surgery is expensive and an unbearable burden for patients. Facial skin capillary hemangioma can be combined with cosmetic skin grafting to repair the diseased area. Therefore, surgical treatment should strictly grasp the indications, weigh the value of surgery, and then determine whether to choose surgical treatment.
        2. Cryotherapy: This method for the treatment of hemangioma originated in the 1960s (small areas of superficial lesions can be used as appropriate). The operator uses the strong low temperature (-96°C) caused by the volatilization of liquid nitrogen, which is usually low At -20°C, condense the skin, hemangioma and surrounding tissues in the lesion area to form ice crystals in the cells, causing the cells to rupture, disintegrate, and die, and then go through the body repair process to make the hemangioma disappear. However, this method will leave local scars, and often leave severe deformities and dysfunctions after treatment in the eyes, mouth corners, nose tip, and ears. Because it is difficult to control the intensity and depth of the freezing operation, and the tissues have different resistance to low temperature, the treatment is incomplete. The recurrence is relatively high, which directly affects the evaluation of curative effect. In addition, the local scar defect deformity dysfunction is not the result expected by the recipient, but if such a condition does not occur, the treatment is often ineffective.
        3. Radiation and isotope therapy: The principle of treatment is to use r-rays generated by radioactive elements to bombard the nucleus of tissues in the lesion to break the DNA and RNA strands, stop the synthesis of nucleoprotein and cause cell death and disintegration. To achieve the purpose of treatment through the process of tissue repair. Commonly used clinically are: shallow X-ray irradiation, cobalt 60 local irradiation, strontium 40 film external paste, phosphorus 32 colloid local injection and so on. After the treatment, atrophic scars were left on the treated part after radiation injury, and the epidermis was desquamated. For this kind of atrophic tissue and atrophic scars caused by radiation exposure, experts recommend surgical resection, otherwise the possibility of cancer cannot be ruled out. Experts believe that radiation therapy should be avoided as much as possible during the treatment of hemangioma.
        4. Sclerosing agent injection therapy: This method originated in the 1950s, when the injection therapy of sclerotherapy was derived. The principle is: inject the sclerosis into the hemangioma tumor tissue (cannot be injected into the blood vessel), causing aseptic inflammation, local fibrosis reaction occurs after the swelling disappears, and the hemangioma and the vascular cavity are shrunk or occluded. Commonly used drugs are: ①Sodium morrhuate; ②Kuzhiling injection; ③Alum injection; ④Kufan Huanglian injection; ⑤Sodium bicarbonate injection; ⑥Pingyangmycin, bleomycins; ⑦Boiling water injection Therapy; ⑧Urea injection.
        5. Laser treatment: Use professional laser treatment equipment to coagulate hemangioma tissue and achieve the purpose of treating hemangioma. However, the depth of laser treatment is generally controlled within 0.2～0.4mm of the superficial skin. If it exceeds 0.4mm, it will produce obvious scars. Therefore, it has a certain effect on superficial capillary hemangioma, and it is easy to cause bleeding and scar deformity on deep hemangioma.
        In addition, photosensitive laser therapy (also known as photodynamic laser therapy) is to inject a photosensitizer into the patient's blood vessel, and then irradiate the hemangioma area with a black light lamp or a long-wavelength laser. After the photosensitizer is activated, it produces a photochemical reaction and leads to a light process in the vascular intima and interstitium of the hemangioma, so that the vascular lumen is occluded to achieve the purpose of treatment. However, this therapy must be strict in the treatment process, otherwise severe photosensitive endositis and photosensitive retinitis after fibrous tissue disease will occur.
        6. Interventional therapy: refers to the introduction of arteriovenous catheters into the hemangioma site under the guidance of "X", and then injecting embolic agents into the tumor body to produce aseptic inflammation, in order to achieve the effect of occluding the tumor blood vessels. Often used for visceral hemangioma such as liver hemangioma. For deep hemangioma of the trunk and limbs, it is often difficult to achieve the expected results due to the limitation of the injection dose, the dosage form, and the characteristics of the hemangioma. Strictly control the indications and avoid the embolic agent from flowing into other organs and tissues.
