DCIS not sure how to feel

I can't add much to what others have said except to stress what @primek has written.  If 1 in 8 (or 1 in 7 as now is being said) Australian women will be diagnosed with BC, it stands to reason that most people around you have direct of indirect experience of it.  I doubt that anyone is going to judge you or have anything but compassionate feelings for what you are going through.  I don't work in the medical field but since going through my treatment I have since heard of a number of women in my workplace who have had BC too - they just didn't feel comfortable with others knowing and prefer to keep it quiet.  I understand this but when it comes to treatment, you need to go for the best you can afford and it sounds like that means public.  And your colleagues may want to look after one of their own that little bit more.
