  1. There are some great shows on TV which cover subject such as advanced breast cancer but most of us don’t have time to watch them so it’s good that we can find information like this on the net.

  2. I spent a good couple of hours on Saturday researching advanced breast cancer and your post was one of the very last ones that I came across. By then I’d begun to start thinking about other things but your post brought my attention back to the subject I should have been thinking about. Thanks for the insights and taking the time to write the article. It was useful to me.
