When breast grow they can sometimes itch. A lot of women experience sore breasts at different points in their menstrual cycle. I can say that dry, itchy breasts are not a common symptom of pregnancy. If your friend has been sexually active, and there is a chance she could be pregnant, the over the counter tests at the grocery store are pretty reliable ( not 100%).Either way, if this is new and unusual for your friend, she should speak with her medical provider.
