- Stage 1A Endometrial Cancer
- Stage 1B Endometrial
Overview
Stage 1A Endometrial cancer diagnosis means that the cancer has been found only in the mucus membrane lining of your uterus, called the Endometrium, or the cancer is less that half way through the Myometrium as shown at the top of the image.
The Endometrium is the part of the uterus that thickens during your menstrual cycle to prepare for the potential arrival of an embryo. The Myometrium is muscle layer of the uterus.
What Tests Will I Need and Why?
Blood and Imaging tests are done to understand your general health, confirm your diagnosis and determine your cancer stage.
Tissue analysis is also typically done through a biopsy to identify the cancer cell type, which is critical to finding the best treatment option for you.
If your treatment team has not already performed tests to determine your cancer’s features, please ask your doctor when these tests will be performed.
