I had a d & c recently, age 53 and the microscopy show sections showing predominantly blood clots, mucus and scanty inactive benign endometrial glands?

Sounds great: If you have abnormal bleeding or post-menopausal bleeding, one of the most definitive ways to evaluate this is a d;c. Your results are completely normal and of no concern.

Good news!: That's a benign result. So that's good news. I'm sure that's what your doctor was hoping for.

Likely atrophy: Scant inactive endometrial glands and blood is usually a good indication that the cause of bleeding was endometrial atrophy (thinning of the uterine lining related to age). This is common in post menopause. GYN should be sure that he/she sampled the uterine cavity well. If so, then pathology consistent with atrophy and doesn't show hyperplasia or other causes of bleeding.
