In theory the omentum might stop your ovarian cancer from spreading to other organs for a period of time. In practice..you would have to catch it while it is still in that stop gap.
I suspect that rarely happens because it is most often not caught until it effects other organs
I advocate at risk patients getting periodic ultra sounds even if insurance doesn’t pay for it. It might help save your life
Also there is a test that might red flag you sooner if you are in menopause
Inhibin tests.
A bad inhibin test does not mean you have cancer but does mean you should now get to work to see what may be happening
