Meningiomas account for approximately 44% of all intracranial tumors in females and 21% in males. 74% of all diagnosed meningiomas occur in women. They are the only variety of central nervous system tumor diagnosed more often in women than in men and can oocur at any age but seem to be more prevalent in women over 40.
So, the obvious question to the above facts would be why more in women than men? We know we are diffeerent so surely there has to be an outstanding reason?
The only known risk factor for meningiomas is previous exposure to ionizing radiation of the head, such as being exposed to the radiation while being treated for a previous brain tumor. It has also been discovered that there is a correlation between the disease Neurofibromatosis and meningiomas. I was also advised that it could possibly be a chromosomal abnormality but due to so many not being diagnosed and the lack of funding for research in this area the reasons are largely unknown.
What we are told is that there is certain evidence that elevated levels of female hormones may promote growth or regrowth of meningiomas and these facts could account for the percentage rates above.
It could be that whilst we thought we were taking a proactive stance in looking after our bodies ladies, in a controlled fashion, the benefits of such hormonal medication as birth control, infertility treatments, hormone replacement therepy may be outweighed by the risks for a percentage of women and these medications should certainly be discussed fully and carefully for any women who have previously been treated for a meningioma.
