The central nervous system embryonal tumours are malignant or benign cells that start in the embryonic or fetal cells that remain in the brain post birth. These tumours tend to spread via the cerebrospinal fluid to the other parts of the brain as well as spinal cord. The tumours can be either malignant or benign. Most of the CNS embryonal tumours in children are malignant in nature.
Malignant cancer cells have a characteristic of growing quickly and spread into different parts of the brain. When the tumour grows into or presses on the area of the brain, it can stop that part of the brain from performing or functioning the way it should. The benign brain tumours can grow and press on the nearby areas of the brain and spread to other parts of the brain very slowly. Both benign as well as malignant brain tumours can cause different signs and symptoms.
Even though cancer is a rare condition in children, the brain tumours are the third most common type of cancer occurring in children after lymphoma and leukemia.
There are different types of CNS embryonal tumours. These include the following:
These are fast-growing tumours that tend to commonly form in the brain cells inside the cerebrum, which is located at the top of the head and is said to be the largest part of the brain. The cerebrum control different human interactions and activities, such as learning, thinking, emotions, problem-solving, voluntary movement, reading and speech. There are four types of CNS primitive neuroectodermal tumours.
Most of the CNS embryonal tumours are medulloblastomas. These are fast-growing tumours that form in the brain cells inside the cerebellum. This cerebellum is located at the rear of the brain i.e. between the brain stem and the cerebrum. The cerebellum is said to control movement, posture and balance. The medulloblastomas tends to spread to the bone, lung, bone marrow or other parts of the body, but this is a rare medical condition.
