Ductal carcinoma in situ (DCIS) is a non-invasive form of breast cancer that starts in the milk ducts (mammary glands) and has not yet spread to nearby tissues. Hormones, especially estrogen, can fuel the growth of some DCIS, making it hormone receptor-positive. Understanding the hormone receptor status of DCIS is crucial for determining the most effective treatment plan. At the Texas Breast Center, we provide comprehensive evaluation and personalized treatment plans for DCIS and other forms of breast cancer.
