If you were recently diagnosed with DCIS (Ductal Carcinoma In-Situ), of the breast we invite you to participate in a research study which aims to improve medical treatment for your condition.

If you participate, you will help us test the effectiveness of a new way of using tamoxifen, which we think will be safer than the current tamoxifen pill, but just as effective. This new, direct way of delivering tamoxifen to the breast as a gel applied to the skin, may avoid side effects caused by tamoxifen pills.
