Cancer is cancer is cancer and ANY diagnosis hits you for a 6 - and DCIS, tho less likely to become invasive, apparently 'can' become invasive, if not treated in time ....
How incredibly insensitive of your relative to say that, specially working in the BC Screening area. :(
Sadly, there are some who don't really 'think' before they speak.
We had a thread called "Did they really say that'' - and there are some DOOZIES there!!
