What happen to the brain and the brain cavity?
Gnoma [55]

Answer: OK so The ventricles of the brain are a communicating network of cavities filled with cerebrospinal fluid (CSF) and located within the brain parenchyma. The ventricular system is composed of 2 lateral ventricles, the third ventricle, the cerebral aqueduct, and the fourth ventricle (see the images below).Survival in untreated hydrocephalus is poor. Approximately, 50% of the affected patients die before three years of age and approximately 80% die before reaching adulthood. Treatment markedly improves the outcome for hydrocephalus not associated with tumors, with 89% and 95% survival in two case studies

What genes destroy cancerous cells?  The primary function of the p53 gene is to repair or destroy defective cells, thereby controlling potential cancerous cells. This type of gene is called an anti-oncogene or tumor suppressor gene Cancer growth blockers are also called cancer growth inhibitors. They are a type of targeted cancer drug.  Our body makes chemicals called growth factors that control cell growth. Cancer growth blockers work by blocking the growth factors that trigger cancer cells to divide and grow. There are many types of cancer growth blockers that work in different ways..
