Understanding Glioblastoma
Is Glioblastoma Inherited? Glioblastoma is a serious brain cancer. It is the most common malignant brain tumor. Unfortunately, it’s also the deadliest in adults. Because it grows fast and invades nearby tissues, it’s hard to treat and manage. Scientists are working hard to learn more about its genetics. Knowing the risk factors will help find better treatments.
The Acibadem Healthcare Group says glioblastoma’s aggressiveness comes from its complex genetics. The way glioblastoma grows and resists treatment is tied to its genetic mutations. Research shows these mutations are what make it hard to stop.
Finding risk factors for glioblastoma is key for early detection and prevention. Genetic and environmental factors can raise the risk. For example, certain genetic syndromes can make someone more likely to get glioblastoma. This shows how important these genetics are. Is Glioblastoma Inherited?
