Oh Holly, I am so sorry to hear that IT came back! What is the pathology of it? Is it a new primary and in the same area?
When you were taking the collagen, did you find it helpful at all? I have been willing to try anything for relief and marketers don't even think about the long term affects of people.

Here in the states, one can buy anything off the shelf.
