Women have much greater risk than men of developing meningioma, a type of tumor in the membrane lining the brain and spinal cord. The cases vary widely in severity of symptoms. Approximately 90 percent of meningiomas are benign; the remaining 10 percent are malignant (cancerous). Some of the benign tumors are small and cause no symptoms, so according to Mayo Clinic authors, no treatment is required. But the malignant ones are aggressive with high rates of illness and death. Treatments include surgery, radiation therapy, and chemotherapy.

Overall, meningiomas occur twice as often in women as in men. This difference leads researchers to consider sex differences, such as estrogen levels, as a risk factor. A recent study of 350,000 women indicated that the risk of meningioma was about twice as high in those who used postmenopausal hormone replacement therapy. The group included 1,400 women who developed this type of tumor.

Breast cancer has a strong association with meningioma in women. So is there something other than being female that causes this? Men get breast cancer too, just not as commonly as women. A group of researchers at The University of Texas M D Anderson Cancer Center examined records from five state registries to see whether the association between meningioma and breast cancer also applies to men. This was not the case. Thus, whatever causes the correlation is specific to women.

Another possible connection was noted between lupus, which affects more women than men, and meningioma. Researchers in Italy identified three cases of women with meningioma in a group of 181 patients with systemic lupus erythematosus. These authors note that meningioma should be considered when lupus patients develop neuropsychiatric symptoms.

A group in Germany examined occupational risks for meningioma as well as other brain tumors (glioma and acoustic neuroma). They hypothesized that workers in the chemical, metal, agricultural, construction, electrical/electronic, and transportation industries could be at higher risk for brain tumors because of environmental factors. However, they found no increased incidence.

The Brain Science Foundation reports that at least 21,000 Americans are expected to be diagnosed with meningiomas this year. This organization created The Meningioma Project to increase awareness. See http://www.brainsciencefoundation.org/matriarch/default.asp.

Thank You so much to the authors for these informative articles about primary brain tumors, especially the low grade types like meningioma. New cases of low grade brain tumors in the US that may or may not be or become cancerous are finally being counted since 2004 by www.CBTRUS.org and there has been an increase in documented cases in the US. Besides an association with breast cancer, there is also a possible association with uterine fibroid tumor cells which look so much the same under a microscope that the slides need to be marked abdomen or head for some ordinary hospital pathologists to be able to tell the difference .
