Sheryl Crow seems to be handling the news of her benign brain tumor better than some of her Facebook friends are. People really like this singer and want her to be well.

Crow announced Tuesday that she’d been diagnosed with a form of brain tumor called a meningioma. That’s the kind I blogged about in April when I reported on a study that found that people with this form of non-cancerous brain tumor were more likely than folks without such tumors to have had bitewing dental X-rays at some time in their past. Meningiomas are more common among women than men, and risk increases with age.

Crow reportedly sought medical care after suffering memory loss — including forgetting the lyrics to her own songs. That’s a common symptom, according to the Brigham & Women’s Hospital’s Web page about meningioma. Crow’s tumor reportedly was detected via an MRI scan.

Meningiomas are tumors affecting the meninges, protective membranes surrounding the brain and spinal column. These brain tumors, though usually not malignant, can cause problems as they put pressure on different areas of the brain.

Meningiomas can be surgically removed, although their location within the brain makes some easier to thoroughly remove than others.  Crow, 50, reportedly is opting for “watchful waiting” rather than immediately undergoing surgery.

Crow was diagnosed with breast cancer in 2006. Research has found a link between breast cancer and meningioma risk, although it’s not clear whether one occurs when the other primary cancer metastasizes to another part of the body. Some research suggests that perhaps hormonal changes that give rise to breast cancer might increase meningioma risk.
