WE are all different - if meno symptoms return they may not be as bad as before - once in post meno, I have found they are less severe.
Hopefully there is no cancer or it's just pre cancer, which is very easily treated. Learn some relaxation techniques e.g. Mindfulness, to help you through this stressful time. If flushes etc do return, then they may settle in a few months.
Keep us posted. Good luck. Dg x
