What are the causes of brain tumors in children?

The causes of pediatric brain tumors are complex and not yet fully understood. However, based on medical research and practical experience, the following factors can be summarized:

1. Genetic factors: Some pediatric brain tumors are associated with genetic mutations, such as neurofibromatosis, von Hippel-Lindau disease, and Li-Fraumeni syndrome, which may increase the risk of brain tumors in children. Specific gene mutations, including RB1, p53, and PTEN, are associated with certain types of childhood brain tumors.

2. Physical factors: Physical factors such as head trauma during pregnancy or after birth, and exposure to radiation may increase the risk of brain tumors in children.

3. Chemical factors: Exposure to certain chemical substances during pregnancy or after birth, such as formaldehyde and pesticides, may also be associated with the development of pediatric brain tumors.

4. Viral infections: Certain viral infections, such as Epstein-Barr virus (EBV) or papillomavirus, are also considered to be potentially linked to the development of brain tumors in children.

5. Other factors: Drug abuse and immune system abnormalities are also considered among the possible factors contributing to pediatric brain tumors.

The exact cause of most childhood brain tumors remains unknown, and in many cases, there are no clearly identifiable risk factors. Therefore, preventive measures are limited, and early diagnosis and timely treatment are crucial for improving prognosis. If you have any concerns about your child's health, please seek medical advice at a hospital promptly.
