What is a hereditary ovarian cancer?
Ovarian cancer is the fifth most common cancer in women. In the general population women have a 1.5% risk of ovarian cancer, with 75% being diagnosed after the age of 55. When ovarian cancer is diagnosed at an early stage more than 90% of women survive more than 5 years, however, sadly this drops to only 5% in those diagnosed at a later stage. Most ovarian cancers occur by chance, however up to 20% is hereditary and in some families it may be possible to find the genetic change (mutation) which is responsible for the cancer. This allows appropriate cancer screening and risk- reducing options.
