ru nuts? Ask a radiologist or MD not people who are not trained to diagnose. btw, patchy density does not necessarily mean cancer at all. I know that from experience. So chill out, go to the beach and meditate. Then start getting second and third opinions if necessary.
btw, density can be from obesity and a lot of things. It does *not* mean that you have cancer. Sorry if I started out sounding mean but please make sure that you get diagnostic advice from doctor specialists.
Good luck.
