Early symptoms are not obvious and can be easily ignored Intracranial tumors in children are commonly seen in children under 14 years old, and also in infants of a few months. Because of their young age and inconspicuous early symptoms, they are easily mistaken for other diseases or ignored by parents. “Take the posterior cranial fossa tumor among intracranial tumors as an example, the child may manifest as occasional headache in mild cases, or continuous vomiting, unstable walking and easy falling in severe cases. However, it is common for infants and young children with unclear expressions or in toddler stage to have unsteady pace, and the symptoms of unsteady walking are often overlooked and treated as gastrointestinal diseases or colds. Another common tumor, craniopharyngioma, can cause short stature, vision loss, depression, and excessive drinking and urination in affected children due to its compression of hormone-secreting locations. However, when children are very young, parents mostly do not pay attention to these problems and think that they will get better naturally when they grow up, so most of these tumors are discovered only after the affected children are in elementary school.” There are malignant and benign tumors mentioned above, and it is especially important to be alert to the life-threatening malignant tumors. Malignant tumors mostly grow in the posterior cranial fossa, because the posterior cranial fossa is small and malignant tumors grow fast, the development of symptoms is often more obvious, parents should quickly take their children to the doctor once they find abnormalities. The sooner the malignant brain tumor is operated, the better. Through CT, MRI and other imaging examinations, the intracranial tumor can be diagnosed quickly. However, parents are in a difficult situation: should they let their children have surgery? Can conservative treatment be adopted because of the high risk of surgery? If a benign tumor is operated, the 5-year survival rate after surgery can be over 95%, which is the most ideal treatment. However, if the tumor is found before the age of 2, the tumor is not very large and the symptoms are relatively mild, you can also wait and observe it regularly. However, for malignant tumors, the earlier the surgery, the better, and there is no restriction for young age, otherwise it will be life-threatening and the post-operative survival rate will be greatly reduced. It is a very common idea that “it is fine if the tumor is cut off by surgery”, but after the surgery, there are still a lot of “work” that the children and parents need to do. In order to consolidate the effect of surgery and prevent tumor recurrence as much as possible, children often need to undergo radiotherapy and chemotherapy after surgery.
