Types of gliomas
There are multiple types of gliomas. Most gliomas
that occur in adults are listed in
. The main
types of gliomas are grouped by the glial cell from
which they derived. Microglial cells do not become
cancer cells. However, they are sometimes found in
and around glial tumors.
Gliomas differ by their cell of origin and by other
features, too. Research has found that glioma
cells can differ in tiny parts, called molecules. Key
molecular features of gliomas are discussed in
Part 2. This information has recently been used by
rganization) to further group
Cancer grades differ among the cancer types.
Astrocytomas range from grade I to grade IV.
Pilocytic astrocytomas are quite different from
other astrocytomas. They rarely occur in adults
but commonly occur in children. Only astrocytes
can be grade IV. Grade IV astrocytomas include
glioblastoma and gliosarcoma.
Symptoms of gliomas
Larger glial tumors are likely to cause symptoms. The
symptoms that may occur partly depend on where
the glial tumor is in the nervous system and how
fast it grows. Common symptoms include memory
problems, headaches, personality changes, seizures,
speech problems, and numbness or weakness in the
arms, legs, or face.
