Hi Karen:
The first step is that your dad's cancer has been found and that he has you for support during the treatment process. The second step, and equally important, is that you have found OCF for support. The people here understand what you are feeling and going through. When my husband was diagnosed with tonsil cancer in 2002, I found OCF accidentally (or maybe not) and besides cutting edge treatment information, I was given a feeling of never being alone and you aren't either.
Welcome...
Kim
