I have metstic bc now for 4yrs and nine months. Even though I have had a bit of a hic cup recently, I am lucky that there is no spread in my organs only in numerous bones. I never asked my oncologist how long I have because I didnt want to know. I had nearly a 2 year break from being on chemo. Just taking the hormone tablet Aromisin. Now it seems to not be working properly so I was be starting back on chemo any day now. I am happy with my oncologist so I think that makes a difference. Dont worry about how long you have , just get out and enjoy life while you can. Well thats my theory.
