doydie,
I pray everything goes well with your sister. I am sure that she is scared and it's great that you are so close and are going through this with her.
It's funny about the wigs because my best friend's sister is very very conservative but bought herself several different colored wigs. She actually had a lot of fun with them and I'm sure that helped her through her therapy to be able to change her look.
I finally had my mammogram about 2 weeks ago and all was well. I was late having since my recent pacemaker surgery makes it hurt a little more than normal. It came back normal.
Take care.
Hugs,
Becky
