Sheryl Crow insists her brain tumor is just "a bump in the road," as she told CNN.
Most likely, she's right. A meningioma, the type of tumor she has, grows in the membranes that surround your brain and spinal cord, according to the Mayo Clinic. They're almost always noncancerous, and between 6,500 and 10,000 people in the U.S. are diagnosed with one each year (and many more never know they have one). Elizabeth Taylor and Mary Tyler Moore each had one, according to CNN Chief Medical Correspondent Sanjay Gupta.
"Please don't worry about my 'brain tumor,' it's a noncancerous growth. I know some folks can have problems with this kind of thing, but I want to assure everyone I'm OK," Crow wrote on her Facebook page.
The tumor was discovered months ago after Crow couldn't remember lyrics to Soak Up the Sun in a performance. The 50-year-old breast cancer survivor told an audience about her condition at a recent concert, CBS reports.
There are rare cases when a meningioma can be life-threatening. A subgroup of the tumor called secretory meningiomas can cause complications in surgery, according to a study in the Journal of Neuro-Oncology.
Often, meningiomas don't require immediate treatment, as appears to be the case with Crow. She will undergo periodic scans, she told CNN.
Meningiomas most frequently occur in older women.
"Some meningiomas are estrogen sensitive," Anders Cohen, chief of neurosurgery and spine surgery at The Brooklyn Hospital Center in New York, told USA Today. "They are usually very, very slow growing. They may start out the size of a pinhead. When women hit menopause, they get these hormonal swings and the tumor may start growing."
