I have just looked it up 😊 Re conversions they word IT differently to vagifem , but it is the same dose as vagifem, and is extremely low minuscule.
The risk of VA taking hold in my non medical opinion , and your breast disease returning from increasing your dose is understandably worrying , but I would say such a small worry it shouldn't be a reason not to up it as necessary.
The type of VA I have been battling for the last two years , has been truly hideous and I would not wish it on anybody , there were times when the alternative seemed like my only alternative.
However I am getting there , from 5 xs vagifem a week and systemic.
I doubt the radiologist will be able to give an opinion , I no some oncologist allow ladies who have had oestrogen positive BC to use systemic HRT as well as local re quality of life etc.
