Transvaginal Ultrasound with: hypertrophy or hyperplasia?

I go through a doctor at a health center, I depend on the date they have for care, I already took my transvaginal ultrasound examination, but I was a bit worried, it says: Endometrial echo: measuring 20.6 mm thick. hypertrophy? hyperplasia I wonder why these two inquiries? What does that mean, thank you for your attention!
