I'm not a doctor, but it seems unlikely that a rash would indicate breast cancer. Sounds more like an allergic skin reaction to something, such as a new soap or laundry detergent or moisterizing lotion.
Well her rash went away, but I saw her recently and she does not look well. She was supposed to go get blood tests done and hasn't done so. Was sick for four days last week and chalked it up to be the flu.
We'll see. She is a procrastinator when it comes to her health, I think it's going to catch up to her.
