Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are individuals aged 18 and over who carry a deleterious BRCA1 or BRCA2 mutation, regardless of whether they currently have cancer.

Probably not a fit

Patients who do not carry a BRCA mutation or those unable to provide informed consent may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study focuses on a cohort of individuals carrying deleterious BRCA1 or BRCA2 gene mutations to assess their genetic predispositions to breast and ovarian cancers. Participants, both men and women aged 18 and over, will complete questionnaires to gather data on their health and cancer history. The study aims to enhance understanding of how these genetic mutations influence cancer risk and outcomes. It will involve ongoing follow-up to monitor participants over time.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into the cancer risks associated with BRCA mutations, potentially guiding prevention and treatment strategies.

How similar studies have gone: Other studies have shown success in understanding the implications of BRCA mutations, making this approach both relevant and supported by previous findings.
