What is the incidence rate of brain cancer?

Intracranial tumors, namely various brain tumors, are one of the common diseases in the nervous system and have great harm to the functions of the human nervous system. Medical experts recommend that everyone pay attention to brain tumor prevention. What is the incidence rate of brain cancer? Let's find out through this article.

Brain tumors can be divided into benign and malignant types. The incidence rate accounts for about 2% of all tumors in the body. They can occur at any age, but are more common in people aged 20-50 years old, with no significant difference between men and women.

According to statistics, intracranial tumors account for about 5% of all tumors in the body and 70% of childhood tumors. 20-30% of other malignant tumors will eventually metastasize into the brain. Due to their expansive and invasive growth, once they occupy a certain space in the brain, no matter whether they are benign or malignant, they are bound to increase intracranial pressure, compress brain tissue, cause central nervous system damage, and endanger the patient's life.

Gliomas account for 45% of intracranial tumors; pituitary adenomas 15%; meningiomas 15%; neurothecomas 7%; congenital tumors 3%; and metastatic tumors and other types of tumors 15%. The overall incidence of intracranial tumors in men and women is roughly the same, but cerebellar medulloblastoma and multiforme glioblastoma are more common in men; while meningiomas and neurothecomas are more common in women. The incidence of primary lymphomas has an upward trend in both AIDS patients and non-AIDS patients.

I believe you already have the answer to the above introduction to the incidence of intracranial tumors. Experts remind that although the incidence of brain tumors is slightly lower than that of other tumors, it is still very necessary to prevent intracranial tumors. If you feel unwell, it is best to go to the hospital immediately!
