Benign: It is always best to gov over the pathology report with your doctor who can interpret the results in the context of your clinical history. Proliferative endometrium is a benign finding. "Fibrinous" is an adjective describing the cellular appearance. There should be a noun after that word to know what the report is calling fibrinous.

Endometrial 2 phases: The endometrium(lining of the womb) grows in two phases. The first half of the cycle it is "proliferative" in response to estrogen. the second half of the cycle post ovulation is "secretory", normally. A biopsy was take due to concerns for cancer and your report shows "estrogen only" phase stimulation. At age 40 your MD may add progesterone to decrease the risk of endometrial cancer.
