| Unlike healthy cells, which perform
useful tasks in our bodies, cancer cells grow in an abnormal, uncontrolled
manner, and instead of contributing to the the normal functioning
of our bodies, they make us sick. There are many types of cancer
which affect different parts of the body. Mo had a solid tumor
which was removed from the part of the brain called the cerebellum.
Thankfully it was discovered before it had spread to other parts
of his body.
Brain cancer in children is a rare disease. There
are about 2200 pedeatric brain tumors diagnosed in the U.S. each year.
Medulloblastoma is the most common form of brain cancer in children
- accounting for 20-25% of the total. No one knows for sure
the cause of this type of tumor. Genetics definitely play a role for
some patients, and it is believed to arise from primitive neuroectodermal
tissue, which is the early fetal tissue that eventually develops into
the brain. It tends to grow quickly, and often spreads to other
parts of the central nervous system. Rarely, it can spread to
other parts of the body.
