700,000. This is the number of people that were living with brain tumors in 2016. Although, brain tumors are not that common. However, 12 people out of 100,000 are likely to be diagnosed with cancer. There are nearly 80,000 diagnosed with cancer each year, in the U.S – but only 32℅ of them are malignant (cancerous) brain tumors.
However, 90℅ of meningiomas are considered benign (non-cancerous). When it comes to primary brain cancers, meningiomas consist of 27℅ of them. That’s why they’re considered a bit common as well.
But, which is the most deadliest type of brain tumor?
Glioblastoma multiforme, also known as GBM, consists of 45℅ of all the malignant brain cancers. Another shocking thing about meningiomas is that before they even show symptoms, they can reach a large size.
Now that we’ve discovered the prevelance of brain tumors, let’s dive into the interesting facts of meningiomas:
1. Risk Factors
People between the age of 40 to 70 are more likely to get diagnosed with meningiomas. Though, it’s more prelevant in women than men. If you’re wondering if a kid you know might have meningioma, they’re extremely rare when it comes to children. So, you don’t really have to worry about it. Just consult a doctor.
There aren’t many factors that lead to the development of meningioma, but previous trauma can contribute to its development. If you look closely, you’ll see that meningomas are often seen at the place of previous trauma. Previous trauma such as a scarred dura or a skull fracture. The confusing fact is that scientists haven’t really discovered what’s the connection between meningioma and brain trauma.
Another factor that contributes to the development of meningioma is radiation. Try not to be too exposed to radiation. It has been linked to a higher risk of meningioma.
