How long should women take these drugs to lower breast cancer risk?
We don’t know the ideal length of time women should take one of these drugs to reduce their risk of breast cancer. The women in the studies took these drugs for 5 years. So, based on this, most doctors recommend that women take tamoxifen or raloxifene for 5 years to lower their risk of breast cancer. The risk was lower during the 5 years the women took the drugs and the lower risk lasted a few years after they’d finished. Researchers are still looking at how long the cancer-lowering effects last.
