Dr. Shaber tries hard to separate fact from fiction because, she says, "rumor and hearsay can start to seem real." In the past, she'd sometimes refer patients to government websites and printed fact sheets, or rely on those outlets to help create her own materials. Not anymore. "As a physician, I can no longer trust government sources," says Dr. Shaber. She is not a political activist or a conspiracy theorist; in addition to her own practice, she's Kaiser Permanente's director of women's health services for northern California and head of the HMO's Women's Health Research Institute. Yet this decidedly mainstream doctor and administrator says, "I no longer trust FDA decisions or materials generated [by the government]. Ten years ago, I would not have had to scrutinize government information. Now I don't feel comfortable giving it to my patients."
