Womb cancer

Hi, i have been told just before christmas I have womb cancer the biopsy shows its low grade I cant remember the name but its the most common type. I had a hysterscopy which every looked v healthy back in sep so it has been a massive shock. Im getting an mri on weds. Then a hysterectomy removal of everything and i cant have hrt I have myself convinced the mri will show up i am full of cancer. Then theres the wait for a result nobody has told me how long that could be. The oncologist nurse i spoke with assured me they can't make things up if im told the biopsy showed low grade then it did and to try to take solace its been got early.
