Hi Cora
I agree with the above , everyone is different and euro have a treatment programme tailored to their individual situation.usually you will have a multi disciplinary team discuss your case whether it is in the public or private system.
This involves the breast cancer surgeon, oncologist and radiation oncologist.
I followed all advice given including mastectomy , radiotherapy and now hormone blockers.
I had confidence in my team and didn’t seek a second opinion.
I did do some independent research on the hormone blockers ( including on this website) and was concerned about side effects but my oncologist stressed how much I would benefit from them and that not everyone has side effects or severe side effects do I decided I would go ahead with them.
Take care.🌺
