Summary

This trial will help determine if surgery to remove the cancer is the only treatment needed for small, early-stage breast cancers.

Who is the study for?
This trial is for individuals with small, low-grade ductal carcinoma in situ (DCIS) of the breast, measuring less than or equal to 2.5 cm. Participants must have had a recent high-quality mammogram and undergone surgical removal with clear margins of at least 1 cm. They should not have invasive cancer, previous breast cancers, nipple discharge, or be on certain cancer treatments like chemotherapy.
What is being tested?
The study is testing if just surgically removing the affected tissue—wide excision—is enough treatment for grade 1 or 2 DCIS without additional therapies. The effectiveness will be observed over time after surgery to ensure all suspicious areas are removed.
What are the potential side effects?
Since this trial involves observation after surgery rather than drug intervention, side effects may include typical post-surgical complications such as pain at the incision site, infection risk, scarring and potential psychological impacts from monitoring without further immediate treatment.
