They're looking for women who have had breast cancer and are currently taking endocrine therapy. Specifically:

• You are a woman who was diagnosed with breast cancer
• You are now taking, or have taken within the past 12 months, one of the following pill-type medications: Nolvadex (tamoxifen), Arimidex (anastrazole), Aromasin (exemestane), or Femara (letrozole)
• You have access to the Internet and are willing to complete an online survey
• You live in the United States

The study is an internet survey.
