DCIS Hormone Therapy
Dear OncoLink "Ask The Experts,"
Has any new information come out at recent conferences about the addition of aromatase inhibitors after 2.5 yrs. of Tamoxifen for estrogen-positive DCIS, after a lumpectomy with clear margins? A consultation indicated that it was not necessary in my case. In my research, I find that 5 yrs. of Tamoxifen is considered adequate for DCIS.
