Breast cancer study tests if watching and waiting is better than surgery for Low-Risk DCIS
NCT ID NCT02492607
First seen Feb 01, 2026 · Last updated May 16, 2026 · Updated 24 times
Summary
This study looks at whether women with a very early, low-risk form of breast cancer called DCIS can be safely monitored with regular mammograms instead of undergoing immediate surgery or radiation. About 2,500 women aged 45 and older with low-grade DCIS will either receive standard treatment (surgery, possibly with radiation or hormone therapy) or active surveillance (yearly mammograms). The goal is to see if active surveillance is as good as standard treatment at preventing invasive breast cancer over 10 years, while avoiding unnecessary side effects.
