A glioma is a tumor that forms in the brain or spinal cord. There are several types, including astrocytomas, ependymomas and oligodendrogliomas. Gliomas can affect children or adults. Some grow very quickly. Most people with gliomas need a combination of treatments such as surgery, radiation therapy and chemotherapy.
7 Μαρ 2024 · The tumor can grow to press on nearby nerves and parts of the brain or spinal cord. This leads to glioma symptoms and can cause complications. Some gliomas develop more changes in their DNA that cause them to become brain cancers. The changes tell the cells to invade and destroy healthy brain tissue.
27 Μαΐ 2021 · Introduction. In 1885, Paul Ehrlich performed a series of innovative experiments using intravenous injection of aniline dye in experimental animals, which ultimately led to the discovery of the blood-brain barrier (BBB). 1 For more than 100 years, our understanding of the BBB has continued to become more profound.
4 Αυγ 2023 · The exact cause of glioma brain tumors remains unknown. However, certain risk factors have been identified: Genetic Predisposition: Some rare genetic syndromes, such as neurofibromatosis type 1 (NF1), Li-Fraumeni syndrome, and Turcot Syndrome, increase the risk of developing gliomas.
20 Ιουν 2024 · Glioblastoma is a type of cancer that starts as a growth of cells in the brain or spinal cord. It grows quickly and can invade and destroy healthy tissue. Glioblastoma forms from cells called astrocytes that support nerve cells.
Gliomas often happen in the cerebral hemispheres of the brain. These are the largest, outermost part of the brain that control many functions, including movement, speech, thinking, and emotions. But gliomas can also first appear in the brain stem.
Gliomas are brain tumours that can be very aggressive and result in death within months; however, people with less aggressive gliomas (low-grade gliomas) can survive for a number of years. Most people are treated with surgery and may also receive radiotherapy with or without chemotherapy.
