Fermara

I have been on Fernanda now for 5 years I had mastectomy n chemo as Well.
The dr said my chose but if I want I can get off Fernanda now as I suffer from urinary tract infections which I never use to, sore joints and now my bone density is declining n I would love to get of it as my dr said that f I go off my percent goes up only my 2% and other people’s I have read about say how good it is when u go off but I thought u have to go for 20 years on fermara. I don’t want cancer again but I would love to feel better. Can anyone give me advice

It keeps coming up with my name but should say Fermara

And should say 10 years not 20, sorry about all the mistakes
