Stress do you think it was a factor in getting BC?

I wondered if my horridly stressed few years that left me with mental exhaustion caused my bc. 

However I'll  never know.

What I do know is now I am looking after myself...mind and body...and try to put myself first.  Breast cancer has taught me that.

I can't change what's happened.  I'm focussing on how I respond to stress now and in the future.
