The omentum—duct tape for surgeons, and useful If a caveman and stabbed by a spear pre surgery days, but otherwise a cancer magnet.
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
