Hi @Cora, this is a difficult question and many more variables are factored into survival such as the detailed pathology results, genetics, lifestyle, one's outlook, other treatment such as chemo etc. Your asking an impossible question.
It's best to discuss these types of questions with your medical team. They are the experts and can explain what difference hormone blockers would make to your future.
If your medical experts are suggesting hormone blockers to give you a greater chance for the futures go for it. All I can say is ask what percentage of your treatment is the hormone blockers? For me I had surgery, chemo, radium and hormone blockers. The hormone blockers are 60% of my treatment strategy. There is no way I would just not have them.
Good luck with your decision.
