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.
Between 6,500 and 10,000 people in the U.S. are diagnosed with a meningioma each year. Approximately 85% of those are non-cancerous, according to Johns Hopkins Hospital.
Meningiomas represent about one-third of all primary brain tumors and are most frequently found in middle-aged women, the American Brain Tumor Association's website states.
Dr. Franco Demonte, a neurosurgeon with MD Anderson Cancer Center told Local 2, "They actually don't really arise in the brain. They arise from the membranes that surround the brain just inside the skull and as they grow, they can impact the brain by going toward the brain."
Demonte said such a small, slow growing tumor is unlikely to cause symptoms.
He explained, "For a meningioma to cause memory problems, it would have to be fairly big and I doubt that's the case that's going on with Miss Crow."
Depending on their size, some people will have their tumors removed right away. Some, like Crow, take the wait-and-see approach, while others might never need an operation or treatment.
Demonte said, "When a tumor, especially a tumor below an inch in diameter, is picked up incidentally or asymptomatically, the risk of intervening is greater than the risk of doing nothing because a lot of these tumors will not grow or really grow so slowly that there's no need to intervene."
Crow remains upbeat, tweeting to fans, "Hey everyone - don't worry about my "brain tumor", it's non-cancerous. Feeling healthy, happy & working on my new record!"
