Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this study is to help us learn more about the roles of genes in cancers that run in families. Sometimes, we are born with genes that are changed or altered. Gene changes are called mutations. Mutations may be passed down from parent to child. Some mutations cause a high risk for cancer. There are two major genes for breast and ovarian cancer. These genes are called BRCA --for breast cancer. If you have a mutation in these genes special actions may be needed. For a person with a known mutation, we will suggest ways to screen for cancer or prevent it. Not everything is known about cancer genes and mutations. The cancer screening we suggest may not always be effective. The aim of this study is to explore these questions. If you agree we will stay in touch with you to follow your medical history. We will also ask you about your family.

This will allow us to measure the cancer risks of known mutations. The study will also look for other cancer genes we do not know about. Whether or not you take part in this study, you may have gene testing. If you take part in this study and wish to know, we will tell your BRCA gene test results.

Beginning in 2019, a subset of participants will be given a follow-up questionnaire regarding their health and well-being.

The investigators may perform genetic testing on the blood or saliva sample in one of two ways: analysis for mutations in the BRCA1 and BRCA2 genes alone or as part of a panel of genes associated with breast cancer predisposition. New technologies are being employed for identification of patients with a susceptibility for developing breast cancer and thus analysis of multiple genes at one time may be offered to you. If this multi-gene testing applies to the patient, a question and answer sheet about this testing will be provided to them by their genetic counselor.
