For most post-menopausal women whose cancers are hormone receptor-positive, most doctors recommend taking an AI at some point during adjuvant therapy. Right now, standard treatment is to take these drugs for about 5 years, or to alternate with tamoxifen for a total of at least 5 years, or to take in sequence with tamoxifen for at least 3 years. Studies are now being done to see if taking an AI for more than 5 years would be more helpful. Tamoxifen is an option for some women who cannot take an AI. Taking tamoxifen for 10 years is considered more effective than taking it for 5 years, but you and your doctor will decide the best schedule of treatment for you.

Are your hormones in tune? Mounting evidence suggests that exposure to light at night -- whether you're asleep or awake -- might play a crucial role in cancer, diabetes, and obesity. The World Health Organization classified "circadian disruption" as probably carcinogenic, and light at night is considered by some to be an endocrine disruptor that may affect melatonin, cortisol, ghrelin, leptin, and testosterone. "Most people think, and the drug companies want you to think, that waking up at night is bad for you," says Richard Stevens, ., a cancer epidemiologist at the University of Connecticut health center. But that's not the case, he says -- it's exposure to light at night that's the problem. "If you wake up at night, as most of us do, that is a period of quiet wakefulness -- stay in bed, in the dark, and enjoy it," Stevens suggests.
