Why Should I Enroll in This Registry?

Why Enroll in This Registry?

Not enough is known about the effects of such medicines as Herceptin® (trastuzumab), PERJETA® (pertuzumab), or KADCYLA® (ado-trastuzumab emtansine) on pregnant women with breast cancer. Do pregnant women who have taken these medicines experience any pregnancy complications? Do their babies experience any health problems in the first year after birth?

By participating in this registry, you can help answer these questions.
