I was dianoised as DCIS and have had 33 days of radiation
Adding hormonal therapy to surgery and / or radiation for DCIS can reduce this risk of developing further breast cancer in the future. To do this the tumor needs to test positive for hormone receptors.
Tamoxifen can be used for early-stage cancers that are hormone-receptor-positive, instead of or following radiation treatment after lumpectomy. Tamoxifen "pretends" to be estrogen and attaches to the receptors on the breast cancer cells, taking the place of real estrogen. As a result, the cells don't receive the signal to grow.
I would question the use of Tamoxifen given that your tumor is estrogen receptor negative.
