@inquirer good morning .. I asked my oncologist about surgically removing the omentum when my cancer recurred and she said that it was not done because USC is a high grade cancer that is systemic with microscopic cells that circulate in the body where as chemo has a better chance of killing everything that's circulating. Also that it's a serious operation with a number of risks. I'm fortunate that my cancer is very responsive to treatment and hopefully it can be managed for many years while continuing my active lifestyle. .. I was told from the beginning that there was no cure for USC but that it is managed through treatment and that has been my experience.
