<s>[INST] I was in a car accident also 2 months ago. I suffered a chest contusion that covered most of my right breast. I have noticed since the bruising has went away, I now have a large indentation on the breast. Do I need to be concern? With what I m read on the web, I m afraid that I met have breast cancer now.
