Sheryl Crow has a benign brain tumor.
It's not causing any problems and shouldn't at all because it's only benign.
She believes she knows why she got the tumor… cell phones.
"There are no doctors that will confirm that. [But] I do have the theory that it's possible that it's related to that. I [used to spend] hours on the old archaic cell phones."
She said the tumor is in the same place she used to hold her cell phone and she thought something was wrong with her when she began spacing out on stage and forgetting lyrics.
She was worried it was early onset Alzheimer and even though a non-cancerous tumor is not something you want, it could have been much worse.
As for the cell phone theory… we think we'll be using speakerphone a little more often.
