Hi there! Everyone reacts differently and it doesn't always follow that the side effects are an issue or maybe only one or two or maybe none. As to which treatment - there's other factors like age, pre or post menopause et cetera
Here's a link to a book on the topic that hopefully you can garner information prior to your appointment and be ready with some questions
Hormone therapy and breast cancer (bcna.org.au)As you progress you will find us on the forum and the BCNA website a wealth of experience and information
Take care and Best wishes with your appointment and ongoing treatment
