Yes, your tumor is given a grade.
A pathologist will look at your tumor and fluids (such as ascites) under a microscope and give it a grade.
Most epithelial ovarian cancers are graded as:
LGSC -- low-grade serous carcinoma
HGSC -- high-grade serous carcinoma.
For other histologic types of ovarian cancers (see Day 8 post) pathologists assign a grade of 1, 2, or 3. Grade 1 is most like normal healthy tissue. Well-defined or differentiated are other terms you may hear for Grade 1. Grade 2 more cells abnormal than normal. They call this moderately differentiated. And grade 3 which is most irregular or poorly differentiated. Grade 3 is believed more likely to spread.
Every Day is a Blessing!
