I was diagnosed with Stage III Invasive Lobular BC at 43. She'll have (I opted for mastectomy(ies), to take away as many chances as I could that it would come back, surgery, chemo and radiation. For me the hardest part was losing my hair. Be sure she finds a wig before starting chemo, or bandanas. I hated a wig, but I was going through chemo and radiation during the hottest part of the summer, so I wore bandanas. Just be there for her, tell her if she needs anything to let you know. We need to be as independent as we can, so someone hovering over us (me and the people I've met along the way have felt this way) isn't good. If she wants to talk, listen, but let her bring up the topic of cancer. Try to treat her like you would before her diagnosis, which I know is hard. You feel so helpless, but you just being there for her, is the great gift you can give her. She'll go through a lot of emotions, which she may or may not show around you, but PLEASE never take it personal if she gets snappy. Not only are we scared, but our bodies are going through some major changes. She's lucky to have you!!!
