Depends on your wife's personality and how she's been taking the news so far, but I know what helped me get thru it was taking charge of the disease and how others treated me because of it. I didn't want anyone's pity, or fearful or sad looks or long comparisons of others experiences and I sure didn't want anyone to treat me any different. My cancer, my way.
After the initial shock and having told hubs and my kids, and the looks on their faces, I was determined that cancer wasn't going to have the last word. I told everyone that if you can't make me laugh and forget what day it was, then please stay away cause I don't need the negativity. I cut my hair (21 inches) before I started chemo, cause I didn't want to lose it all from chemo. I did not wear a wig or a hat unless it was too cold going into winter. I don't think your wife will lose her hair from radiation, I think that's only with chemo. IDK
I did take a 6 month leave of absence from work, but other than that I did everything I had done before......cooking, cleaning, gardening, canning, shopping, etc. This gave me and my family something of a sense of normalcy. But when going out in public I couldn't control strangers reactions and they could be anything from the pitiful looks, or fear and avoiding me as if it were catching. Even a few seemed angry. Whatever......I still held my bald head high and continued on.
Some pointers for you.......treat her the same as always. Let her know by words and actions that you love her and still find her to be the sexiest thing on the planet. Those are just a few things women with breast cancer worry about, after surgery. "will he still love me, will he still want me',......that does NOT mean to follow thru on it, unless she is willing and able. She may be exhausted 24/7, but atleast let her know it. While many men want to 'baby' their women and do everything for them, it really doesn't help her to become too dependent. Although an extra set of hands doing chores, or preparing a meal now & then is always appreciated.
Best wishes for you both.
