If ovarian cancer is diagnosed at the earliest stage, when it is still confined to one ovary, then up to 9 out of 10 women will still be alive 5 years or longer. However, only one-third of ovarian cancers are diagnosed in the early stages.
Unfortunately, many ovarian cancers are diagnosed at the late stage. This means that many women will not be treated until it is too late, and their treatment options may be more limited.
Unfortunately, less than 20% of these women will still be alive 5 years or longer after a late diagnosis.
