Hi thereAnonymous Metastatic Breast cancer is a shock to your system. I’m 6 years down the track. The range of treatment available is so much better than when the 5yrs was worked out.
like you I researched it all and until you dig deeper into those studies you discover they’re older then the new treatments available.
As for the side effects yes they’re rough to start with. Because they’re different. With my treatment I was asked to hang in there to see if they settled down to tolerable which they have. From cancer markers creeping up to now they’re the lowest they have ever been. I’m 68 now and it’s not the mets that are giving me issues now. it’s all mostly age related and being female that gives me grief these days.
You can only give the treatment a go. Only you can decide whats best for you.
