Can children get tumors too? The answer is yes, not only, but also the incidence rate has been increasing year by year in recent years. Many children’s malignant tumors can be cured in the early stage of the disease if they can get reasonable treatment. People often have some wrong views about children’s tumors: first, they think that children can’t get cancer. As a matter of fact, children not only may suffer from cancer at all ages, including the neonatal period, but also may suffer from cancer in all systems of the body. Secondly, it is believed that tumors cannot be cured. In the consciousness of many people, cancer is a terminal disease. This view is not comprehensive. Most malignant tumors in children originate from embryonic mesoderm, mostly sarcomas, which have their own characteristics of occurrence and development different from those of adult malignant tumors. It is an indisputable fact that children’s malignant tumors have a high degree of malignancy and rapid progression of disease, but fortunately, they are more sensitive and effective in treatment (including drug therapy and radiation therapy), and the overall cure rate can reach 60%. The third is not to specialized hospitals by specialist doctors to diagnose and treat. Children’s malignant tumors are special diseases different from common childhood diseases, its diagnosis and treatment have special requirements, without receiving relevant training and practice is unable to make accurate judgments and develop a reasonable treatment plan. Most of the late-stage children seen in the clinic are not detected by their parents in time, but some of them are also due to misdiagnosis and mistreatment by non-specialized doctors. So how can parents be alert to the early symptoms of malignant tumors in children? When parents find that children with the following symptoms should go to the regular hospital in time: 1, unexplained bleeding, including bleeding gums, skin bleeding spots or petechiae; 2, non-nutritional or parasite-induced gradually aggravated anemia, pallor; 3, prolonged and unexplained fever, especially after the antiviral or antimicrobial treatment is ineffective fever; 4, a longer persistent or intermittent pain (headache, abdominal pain, arthralgia, etc.). Joint pain, etc.; 5, certain neurological symptoms, such as headache, vomiting, unsteady walking, facial nerve paralysis, convulsions, etc.; 6, palpable masses, such as the neck, armpits, groin, abdomen, lower back, etc.; 7, enlarged liver, spleen; 8, vision disorders (strabismus, protrusion of the eyeballs, etc.); 9, blood test leukocytes or low or accompanied by a decrease in red blood cells, platelets, and so on. Some of the above symptoms often need parents to carefully observe the child in order to find, such as smaller abdominal mass is often the mother to the child’s bath or sleep when caressing the child and accidentally found. Therefore, careful observation of children by parents or regular health checkups at children’s hospitals are crucial for early detection of malignant tumors in children.
