Never that this would happen to my mother.

I am a thirty old single mother who just found out that mother has breast cancer. We don't know how bad it is.  It was found unknowingly. She had a breast reduction for her back problems and they sent the tissues for a routine pathology check.  Her plastic surgeon called her and told her they found cancer cells.  WHAT A SHOCK. She says it was a blessing that she had this reduction or they would have never found it. She went every year and got check. I don't know how to feel ...... I can't fix this for her and I can't stop this. She is taking so well. She is so worried about being a burden on my sister and I. She says she didn't want to tell us at first. But I am glad she did. I don't understand why bad things happen to GOOD people. When someone can go their whole life doing wrong and hurting people and never face a challenge like this. I can't ask why....I am soooo mad. I have to be the rock for her. She has always been there for me.....I can't imagine her gone this early in my life.
