Most tumours develop from the supporting cells of the brain known as the glial cells. They may be named after the type of cell that they are made up of, or after the part of the brain in which they are found, such as a brain stem glioma. More than half of all primary brain tumours are gliomas.
Grading of gliomasGrading is a term that refers to how the tumour cells look under the microscope. A pathologist will examine the cells and look at whether there are signs they are dividing, how abnormal they look and if there are any abnormal blood vessels.
The grade gives an idea of how quickly the tumour may develop. There are four grades: grade 1 tumours are benign and grow very slowly, whereas grade 4 tumours are malignant (cancerous) and grow faster. Sometimes grade 1 and 2 gliomas are called low-grade gliomas and grades 3 and 4 are called high-grade gliomas. Knowing the type and grade of your tumour will help your doctors plan the best treatment.
In some cases, if a diagnosis cannot be made clearly from the scans, a biopsy may be performed to determine what type of tumour is present. Biopsy is a procedure to remove a small amount of tumour to be examined by a pathologist under a microscope. A biopsy can be taken as part of an open surgical procedure to remove the tumour or as a separate diagnostic procedure, known as a needle biopsy via a small hole drilled in the skull . A hollow needle is guided into the tumour and a tissue sample is removed ). A stereotactic biopsy is like a needle biopsy but is performed with the use of a stereotactic head frame and a computer to precisely locate the tumour and direct the needle. This more complex procedure is used for deep tumours in critical locations.
Information leaflet for patients having a brain biopsy (this is not from our hospital its the only information that I can find that will tell us about being in hospital for a biopsy.
That's it. All there is to report, we are carrying on with life as normal as we can, Sean goes to work and winds up the patients and workmates and I do alot of cleaning (OK so that's not normal) The children go to school and clubs and we pray every night and Thank our Heavenly Father for the blessings we have so abundantly in our lives.
