A negative result to the testing of the BRCA1 gene can certainly give an individual a false sense of security. If the BRCA1 marker tests positive for an alteration, this signifies elevated chances for developing breast cancer and ovarion cancer. However, if negative, the test truly will not tell the individual all too much about their chances of getting ovarian cancer. Studies show that only about 5% of ovarian cancers are a result of inherited defects in BRCA1 and BRCA2 genes; therefore, a negative test result only eliminates a 5% risk of getting ovarian cnacer, which still leaves a very large chance of getting ovarian cancer from other factors. A negative test always results in a sense of security, but without proper knowledge of how much of a risk there continues to be after the testing, a woman may indeed have a false sense of security.
