LUBBOCK, TX (KCBD) - A drug proven to prevent a recurrence of breast cancer may actually increase the risk of a rare form of the disease. The drug is Tamoxifen and it's been applauded for some time, not just in treating breast cancer, but in preventing the cancer from returning.
Now, a study of 1,100 breast cancer survivors indicate that even though Tamoxifen did prevent a recurrence of a common type of breast cancer, it may also increase the risk of a rare form of breast cancer called ER-negative, which usually shows up in the opposite breast. The study at Fred Hutchinson Cancer Research Center says women should not stop taking Tamoxifen, just be aware of the risk.
