I'm so sorry about your diagnosis. Cancer sucks, I have been fighting lymphoma myself for 6 years.
My recommendation would be to go to one of the major cancer centers and seek out a specialist in your type of cancer.
Here is a list of the top ranking cancer centers in the U.S. http://health.usnews.com/health/best...ital-rankings/
I just noticed you are in Australia, I'm not familiar with the health care system there. I would still go and seek a second opinion at a major cancer center there, or here in the US, if you can manage it.
At the cancer center I go to, there are patients from all over the globe.
A larger, teaching institution also gives you greater access to clinical trials and newer treatments. I hope you can find a doctor who is more positive and aggressive.
I wish you the best.
