I stopped taking evista (raloxifene) after taking it for 10 years. Any consequences?

In brief: Breast? likely no

The primary trial of Raloxifene for breast chemoprevention was limited to 5 years of use to match the standard of 5 years of tamoxifen.
Recent data suggest a benefit of 10y of tam over 5 years for treatment of invasive er+ breast cancer. However, the benefit of the extra five years is not seen until after year 10. That suggests that the benefit of that drug holds for 5 years after it is stopped.
