Welcome to healthcare magic,
You have just mentioned your sonography
report and not your symtoms.Regarding the fibroids they are small in size,and if you are not suffering from excessive bleeding no need for any surgery but the worrying factor in your case is ovarian cyst
and not fibroid.As you are 46years old your doctor has to rule out type of cyst-whether infective;benign or malignant.This could be reason for hysterectomy
in your case.I guess your doctor has done blood test
to rule out malignancy,this is an important test which is done if the patient of your age has a cyst.
