The National Brain Tumor Society provides detailed information online. Brain tumors can be benign or malignant, and primary or metastatic. Benign tumors are not considered cancer, but malignant ones are. Primary tumors originate in the brain first. Metastatic tumors develop after a cancer somewhere e...
Gliomas are the most common primary brain tumors either benign or malignant originating from the glial tissue. Glioblastomamultiforme (GBM) is the most prevalent and aggressive form among all gliomas, associated with decimal prognosis due to their high invasive nature. GBM is also characterized by ...

A glioma is a tumor of the glial cells in the brain and spinal cord. Gliomas can range from benign and slow-growing to the most aggressive and malignant brain tumors. Glioma types include astrocytoma, oligodendroglioma, ependymoma, and glioblastoma. Gliomas may be low-grade or high-grade based...
1 Grade I is reserved for subependymal giant cell astrocytoma and pilocytic astrocytoma, which are the most benign in terms of histology; they are generally curable with surgery alone. Because grade I astrocytomas are more common in children than in adults, they are discussed in greater detail ...
It ranges from benign tumours (grade I) to highly aggressive, rapidly progressing tumours with frequently fatal outcome (grade IV). Gliomas Tumours that have histological features that are similar to normal glial cells; that is, astrocytes (astrocytoma), oligodendrocytes (oligodendroglioma), or ...
It is concluded that cerebellar glioblastomas are very rare. This glioblastoma could develop on the way of malignant progression of infiltrating low-grade astrocytoma, or it was a primary tumor induced by radiotherapy.年份: 2005 收藏 引用 批量引用 报错 分享 ...
Fractal dimension has been shown to distinguish benign and malignant breast tumors in both digitized histology5 and ultrasound images19. There is also a wealth of morphological studies on lung cancers20. Within glioma, the lacunarity of T2-weighted MRI abnormalities has been shown to distinguish ...
