I have been taking Anastrozole as post breast cancer treatment since March, 2015. It seems the side effects are compounding as time evolves: insomnia, hair thinning, hot flashes, dry mouth (at night). I think my vision has also been compromised, but that could be age-related, too. I see my oncologist today for a 6-month evaluation. Should I request a different avenue of hormone treatment, and if so, what?
