Gliomas are a formation of cells that grow in the brain or spinal cord. As they grow, they can press on areas of the brain and cause various symptoms. These symptoms depend on the glioma’s location in the brain.
Gliomas are not necessarily cancerous; some gliomas grow slowly and aren’t malignant. However, several gliomas are fast-growing and malignant, taking over healthy brain tissue. Non-malignant and malignant gliomas can affect adults and children, and gliomas can pass from parents to children.
Like every cancer, early detection is key to successful treatment. Late-stage gliomas are usually untreatable, while early detection can mean better and more effective treatment options.
However, gliomas are currently only detected through MRI and biopsy, which are costly, invasive, and potentially dangerous. Scientists must develop a better method to test for gliomas and potentially save thousands of lives.
Now, neurosurgeons at RUDN University have discovered potential glioma markers in DNA. These markers are located in microRNA, which are small sequences of nucleotides.
Genetic testing is an up-and-coming test method. The next step is for RUDN University researchers to conduct research on large samples and acquire data.
There is currently no test for gliomas–but that could change very soon! In the meantime, contact your physician if you have a family history of gliomas and have these symptoms:
- Headache, particularly in the morning.
- Nausea and vomiting.
- Confusion or a decline in brain function.
- Memory loss.
- Personality changes or irritability.
- Vision problems.
- Speech difficulties.
