A recently published study reported that among females with ovarian cancer who received chemotherapy, their risk for breast cancer was lower for the next 5 years. Specifically, incidence rates were lower at 2 years (1.18%) and between 2 to 5 years (1.13%); however, incidence rates rose thereafter for BRCA1 carriers (>4% annually post 10 years). This study shows that the chance of getting breast cancer after an ovarian cancer diagnosis is relatively low. However, it now looks like the rates rise again, especially after 10 years.
