They keep moving the goal posts, I reckon!! Both my brother's Mothers in Law had BC surgery between 20 & 30 years ago - neither had chemo or rads, but was on Tamoxifen for 10 years and neither had recurrences at this point in time. Both are in their 90's (so were younger than me when diagnosed.)
So I was surprised when my Surgeon and Rad Onc said the AIs would only be 5 years!
For every report suggesting 5 years, I reckon there are the same number of reports advocating 10 years! If it gives you peace of mind - go with the 10 years! ;)
Take care & all the best with your ongoing treatment xx
