If you were diagnosed with breast cancer, what is the chance of you getting ovarian cancer?

5%: Women with a personal history of breast cancer have a 3-fold increased risk of ovarian cancer. This association is even higher in women with a brca mutation, who may have a15-45% risk of ovarian cancer.

Depends: If there is no other significant risk factors that indicate possibility of having a particular genetical abnormality i.e. Brca1 or 2 or lynch syndrome- such as- young age of cancer diagnosis or family history of ovarian, breast cancer or other cancer such as uterine/colon etc in 1 or more generation- then the risk to have ovarian cancer will be the same as the general population.

Varies: If your breast cancer was caused by a mutation in the brca gene, then your risk of ovarian cancer is greatly increased.
