Hello and thank you for posting your query on HCM
On the basis of your CT and ultrasound
findings, I would suggest you to go for an Endometrial Biopsy
I this procedure a small bit of endometrial tissue is taken out and examined for any abnormality.
Secondily, the ovarian cyst
that you have developed need not be a cancer. It could be a benign cyst
which can be removed by a surgery.
Although 1 year has not passed since you have ceased to have periods, you are in peri-menopausal stage.
HOwever, this term is not used very frequently and women once cease to menstruate are safely referd to as post menopausal.
I hope your query is solved.
Thanks and take care
