Brain Tumour Types
The term brain tumour is describing a wide variety of entities. The tumours differ through its growth, the expected prognosis and their response to therapy as well. Therefore, the accurate diagnosis and classification of a detected tumour has fundamental importance for its treatment.
The exact diagnosis is made by using different imaging techniques and pathological examination of tumour tissue. The World Health Organization (WHO) distinguish four different tumour grades:
WHO grade I (benign)
WHO grade II (still benign)
WHO grade III (already malignant)
WHO grade IV (malignant)
WHO grade I corresponds to a benign, slow-growing tumour. WHO grade IV, in contrast, is typically a particularly virulent and fast-growing tumour. Below is a selection of the most common brain tumours listed.
