Ask an Expert: Chemotherapy and insomnia

Q: I'm undergoing chemo, and though I am experiencing heavy-duty fatigue, I am also suffering from insomnia! Sometimes it's hard to fall asleep; other nights I wake up around 3 a.m. for an hour or two. My medical oncologist said chemo can disrupt the sleep-wake cycle and prescribed Ambien. I don't like the idea of relying on a sleeping pill. Anything else I can do?

Answer from Miles Hassell, M.D., director of Providence Integrative Medicine at Providence Cancer Center:

Ask an Expert: Should I request a thyroid guard during a mammogram?

A recent chain email, forwarded by a friend, has me concerned. The email focuses on a recent episode of “The Dr. Oz Show,” in which Dr. Mehmet Oz suggested that radiation from mammograms and dental X-rays could be partly responsible for increasing rates of thyroid cancer. According to the email, thyroid guards are available to protect patients during dental and breast imaging, but are not routinely used. My questions: How serious are these thyroid risks? Should I insist on using a thyroid guard when I have dental X-rays and mammograms?
