(CNN) -- Singer-songwriter Sheryl Crow says she has a brain tumor, something she described to CNN on Tuesday as a "bump in the road."
"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," she wrote on her Facebook page.
Crow, a breast cancer survivor, spoke to CNN Chief Medical Correspondent Sanjay Gupta, a practicing neurosurgeon, about the diagnosis.
She told him the tumor was discovered months ago. Crow doesn't need surgery but will have periodic scans to monitor the growth, she told Gupta.
According to the singer's representative, Crow was diagnosed with meningioma, a common type of brain tumor.
Elizabeth Taylor had one; so did Mary Tyler Moore, said Gupta.
"It's a tumor that typically grows between the outer layer of the brain and the brain itself. So it's not actually inside the brain," he said.
Depending on their size, some people will have theirs removed right away. Some, like Crow, take the wait-and-see approach, while others might never need an operation or treatment.
"Really appreciate everyone's love and concern, I feel so blessed to have the support of all my fans, but I'm good -- really!" wrote Crow.
