I'm so sorry for your loss! Certain mutations of the BRCA1 and BRCA2 genes increase risk for breast and ovarian cancer. But being tested for these mutations can put you in a quandary as to whether to have ovaries and/or breasts prophylactically removed.
I worked with a woman who had a very strong family history of both breast and ovarian cancer. Her sister and at least one aunt had ovarian cancer. Her mom and several aunts had breast cancer. But her gyn said her ovaries were too important to have them prophylactically removed so he monitored her closely. She still had her ovaries last time I saw her and she was close to age 50.
The uterus and ovaries have lifelong functions. Their removal has serious health consequences. Here's a short video detailing their functions and consequences of removal -

My life and health have been in a tailspin ever since. I became suicidally depressed (never had depression before). I also aged 10-15 years almost overnight despite being on estrogen. I now have the inevitable post-hyst big belly and back pain due to the loss of pelvic integrity.
Please research and be sure you know your personal risks for OC before making this serious decision. Also, there are diet and lifestyle changes you can make to reduce your risks.
Hope I've been of some help!
