Brain cancer grading
Brain cancer grading is much different than staging other cancers in the body. Cancers in the lung, colon and breast are staged based on their location in the body, size, lymph node involvement, and possible spread. Tumors in the brain are graded based on how aggressive the tumor cells appear under a microscope.
The grade and resectability of the tumor will help guide treatment decisions. Surgery depends on the tumor’s accessibility (location), size, extent (spread within the brain) and the patient’s overall health (including medical history).
