Purpose of Study

The purpose of this study is to determine if self-collected vaginal swab specimens can be used to detect the mutation status of an individual’s BRCA gene. If proven, this method could offer a simple, accessible alternative to blood-based genetic testing, potentially making population-wide genetic testing for hereditary cancer risk more feasible in B.C.

After consenting to participate, participants will be mailed a vaginal swab self-collection kit. At home, participants will collect their own vaginal swab sample in the provided tube. The process will take 10 minutes or less. After collecting the sample, participants will mail it back to BC Cancer Research Laboratories in the return envelope and record the date when they received, completed and mailed back the sample in an online questionnaire.

Eligibility

This study is open to individuals who were assigned female at birth (inclusive of all gender identities) and are between 19 to 50 years of age. Participants must have had genetic testing with a blood test at a validated lab that tested for BRCA1/2 mutations (among several others), also known as multigene next generation sequencing, and received either a positive or a negative result. Participants must also be willing and able to self-collect vaginal swab following written instructions.
