35yrs old & I've just been diagnosed with DCIS...

Hi beautiful ladies (and some men too!). I'm a 35 yr old unpartnered person still living in a sharehouse with no kids, and this feels so incredibly weird.  So far I've read about people with husbands, who are older with kids.  I currently live in a different city to my family and so having something like this web community is going to be a great resource.  Is there anyone out there in a similar situation or age group? 

At the moment I'm facing the possibility of mastectomy vs radiation.  Any advice about this is also very welcome.
