Hi @Cora
As others have said , none of this is easy.
The survival rate for breast cancer in Australia is very high and the treatments offered will all be geared to helping you survive .
As to side effects , some people tolerate treatments better than others and you won’t know until you start how you will react.
I had double mastectomy , radiotherapy and now hormone therapy.
I was lucky I didn’t need chemotherapy, but if I had been recommended it I would have had it as I want to give myself the best chance of survival .
But of course it’s an individual decision .
I found very helpful the blog and book by the UK breast cancer surgeon ( Dr Liz O’Riordan) who herself got breast cancer - she realised she never really understood what her patients had been going through until she became a patient herself.
Take care.🌺
