Currently, the incidence of malignant tumors in children is increasing. Given that such diseases are mainly related to heredity, experts suggest that young parents must pay attention to lifestyle habits and pregnancy health, while it is best to have regular medical checkups after the child is born. Grief From onset to death, 8 days “I have a very distressing case in my memory.” In 2011, an 8-year-old child suddenly suffered abdominal pain while playing and was hastily carried by his parents to the pediatric general surgery department of the Third Affiliated Hospital of Zhengzhou University, said Chen Qi, chief physician of the pediatric general surgery department. Color ultrasound examination revealed that the child’s abdominal cavity had been filled with neuroblastoma, a malignant tumor that had metastasized extensively and was already present at the time of the child’s birth, but because it was discovered too late, it was already at an advanced stage, and the child unfortunately died eight days later due to ineffective medical treatment. “Afterwards, the child’s parents asked why they didn’t find any abnormality in the child since childhood? How can early detection of tumors in the child’s body?” Chen Qi said that a physical examination, through ultrasound, chest X-ray, blood and urine routine, will be able to detect these tumors. Subsequently, the child’s grandfather took all the grandchildren in the family to the Zheng University Third Affiliated Hospital for medical checkups, and fortunately none of the children were found to have any problems. But the grandfather said that he would take the children to the hospital for medical checkups every year from now on. The key to early detection and early treatment is to closely observe and regularly check children’s tumors, although they are very dangerous, are relatively easy to cure. Chen Qi said that most childhood tumors are congenital and some of them can be detected during perinatal health care during pregnancy. Many teratomas are mostly benign and can be surgically removed, but after one year of age, the malignant tendency starts to be obvious. For example, “sacrococcygeal teratoma” is 70% benign and 30% malignant before the first year of life, but after the first year of life, it is exactly the opposite: 30% benign and 70% malignant. At the same time, the vast majority of childhood tumors are characterized by painless masses. Parents should carefully observe whether there are lumps on their children’s body when bathing or sleeping and touching them. Some tumors are hidden, so the child can go to the hospital for physical examination after the first month of life. Most of the items of physical examination are ultrasound, chest X-ray and blood and urine routine, which are not harmful to the child’s body. At present, for children’s tumors, most of them adopt surgery plus chemotherapy. Chen Qi said that the prognosis of children’s tumors is generally very good, because children’s psychological development is immature, so when treating tumors, they are not as much psychological burden as adults, in addition, most of children’s tumors develop from immature embryonic tissues, which are relatively more sensitive to chemotherapy. In addition, children are in the stage of growth and development, so their bodies recover quickly after surgery and chemotherapy.
