@cynthiaslife There are different kinds of endometrial cancer and endometrioid adenocarcinoma is one kind. That was my diagnosis also and I subsequently learned it is the most common of all the endometrial cancers. Of course no one of us who has been diagnosed with this thinks of it as "common".
Here is something to read about endometrial cancer.

Would you be willing to share your surgical plan? Will you have a laporascopic

It was difficult to believe at the time but it was same-day surgery. In very early in the morning and out by 5 pm once I was comfortable walking on my own.
