The study counters prevailing wisdom that excess weight impacts mortality only in extreme cases and sheds light on the pitfalls of using Body Mass Index (BMI) to measure health outcomes.

Previous studies have suggested a possible link between head injury and increased rates of brain tumors but evidence has been limited and often inconclusive. A team has now identified a possible mechanism to explain this link, implicating genetic mutations acting in concert with brain tissue inflammation to change the behavior of cells, making them more likely to become cancerous. Although this study was largely carried out in mice, it suggests that it would be important to explore the relevance of these findings to human gliomas.
