Hereditary Breast Cancer Treatment Study (Treatment Study)
About the Study
The Treatment Study is an international research study to better understand breast cancer treatment among individuals with , and gene mutations. Participants are asked to complete online or paper study questionnaires (every two years for 10 years) and share their family history, medical, and genetics records.
Research shows that , and mutations increase the risk of developing breast cancer; however, it is not clear how to best treat or reduce the risk of these hereditary breast cancers. Learning more about breast cancer among those with , and mutations will help to better understand:
- If people with -, - and -associated breast cancer have an increased risk of developing a new breast cancer
- The best treatment for breast cancer patients with an , or mutation and how to improve survival outcomes
- How healthy family members who carry , and mutations can best manage their cancer risks (through screening, preventive surgery, etc.)
Through a better understanding of these hereditary breast cancers, we can personalize breast cancer treatment to improve survival and determine how to best manage at risk family members to detect cancer early or prevent it.
