Can endometrial cancer be discovered by just a transl ultrasound?

I was diagnosed with endometrial hyperplasia 2 months ago during an ultrasound. My transl ultrasound also showed abnormalities like an enlarged endometrial stripe. I go back on the 14th because the head of radiology requested for me to have another ultrasound to see if the stripe was still enlarged, the results my primary care physician showed me also said that cancer cannot be ruled out in the patient (me) due to age. (I'm only 22).
