This study investigates ductal carcinoma in situ (DCIS), a condition where abnormal cells are found in the lining of a breast duct. The purpose of the study is to compare cases of DCIS that either did or did not recur as invasive cancer.
Participants will undergo various study procedures to collect data on DCIS cases and their outcomes. The study aims to understand the factors contributing to whether DCIS recurs as invasive cancer.
- Who can participate: Individuals aged 18 and older with a history of ductal carcinoma in situ (DCIS), either with or without recurrence as invasive cancer, may be eligible to participate.
- Study details: Participants will be required to provide medical history and undergo assessments to evaluate their DCIS condition. The study may involve collecting samples and other relevant information.
