A pathogenic and likely pathogenic variant or deleterious mutation has a serious negative impact on the function of the gene. This means a higher risk of developing breast or ovarian cancer. It does not mean that person WILL develop cancer.
A benign variant has no impact on the function of the gene: even with this difference in its code, there is no deleterious impact. A large amount of the population carries benign variants with no development with cancer.
There is a third possible result, a variant of unknown significance may have an impact on the function of the gene but the cancer risk has not yet been determined yet due to low clinical cases.
These (and all) BRCA test results are discussed with a health professional who is knowledgeable about BRCA testing.
