A recent study has found a link between traumatic brain injury (TBI) and brain cancer. People with moderate to severe head injuries are more likely to have fatal brain tumors. The study analyzed data from more than 75000 people. Let's know about this study in detail.
We all heard from elders in childhood that do not hit on the head or do not let the head get hurt, otherwise there will be trouble in the future. This is because the head is a delicate part of our body and this is why health experts also always advise to take care of the head. Now a shocking revelation has come to light in a recent study proving this to be true.
This latest study found that medium to severe head injury can later cause brain cancer. Today in this article we will know about this study in detail. Let us tell you what this latest study says-
What does the study say
Recent research, in which more than 75,000 individuals suffering from traumatic brain injury (TBI) were analyzed on a large scale. This shows that people with moderate to severe injuries are very likely to have malignant brain tumors. A study analyzed the health data of more than 75,000 participants between 2000 and 2024, monitoring individuals suffering from mild, moderate or severe TBI.
Connection between head injury and brain cancer
The results of this study were shocking. 0.6% of people with moderate to severe TBI developed malignant brain tumors within three to five years of injury. While this percentage was much lower in individuals with no history of injury. On the other hand, mild TBI did not increase the risk of cancer.
Moreover, a hospital-based case-control study in Afghanistan found that individuals with a history of head injury were 2.6 times more likely to develop brain tumors than those without such injuries. Similarly, in Rio de Janeiro, Brazil, a study showed a 1.49 times higher risk and the association was even stronger with increasing number of head injuries.
How does head injury cause brain cancer?
After a head injury, inflammation and changes in cell behavior can affect certain brain cells such as astrocytes. In such a situation, if genetic mutations are already present, these cells may be more likely to turn into cancer over time. In addition, a meta-analysis of several studies has shown a slight increase in the risk of brain tumors, especially glioma and meningioma, after head injury.
Are all brain tumors and injuries the same?
This study also revealed a worrying link between head injuries and the risk of developing brain cancer. However, it is important to note that not every type of brain tumor is linked to head injuries. Furthermore, while rare, head injuries increase the risk of dementia, not cancer, highlighting that different types of injury can lead to different outcomes.
