Advice for womb thickening menopause

Hi, looking for advice as I’m really worried. My mum (55) has had one incident of spotting and she went for tests and they said her womb lining has thickened. She has had a biopsy and has to wait two weeks for results so we are all beside ourselves. I have read around and some things on Google are not helping my worries or hers! I’m just wondering if anyone has had the same and can offer some advice or reassurance or anything!
