Should less treatment be offered to 'older' women with BC? Over 70s ....

I was diagnosed last year at 73. I have to say I was treated wonderfully by my surgeon, both my raiotheraphy oncologist and my medical oncologist. No one mentioned my being in my 70s except my radio oncololoist who said it was nice to have a 'younger' patient - she'd had women in their 80s for treatment recently.
I certainly hope women over 70 don't get written off as not worthy of treatments.
