Sheryl Crow suspects that the benign brain tumor she has may have been caused by her cell phone.

“There are no doctors that will confirm that,” Crow, 50, said Monday while appearing on the premiere of Katie, the new syndicated talk show hosted by Katie Couric.

“[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.”

Crow, who says the tumor is in a part of her brain near where she often held her phone, says she started to suspect something was wrong when she began spacing out on stage, forgetting lyrics and generally feeling “mushy.”

“I [was] worried I had an early [onset] Alzheimer’s,” she confesses.

Many around her downplayed the symptoms, saying it was normal for a busy mom of two young sons to feel that way.

In the end, Crow says the non-cancerous tumor is “nothing I have to worry about,” but, for the breast cancer survivor finding out she had a tumor was “definitely a sobering moment.”
