I am sorry to hear about your situation and can appreciate you having questions.
At the moment it sounds like your specialist doctor is running some more tests to gather further information about your cancer. From there they will be able to discuss with you the best treatment moving forward.
Unfortunately as there can be varying amounts of uncertainty with cancer, the word curable isn't often used by doctors. Most cancers are treatable to varying extents but it is only the doctor involved in your care who can say what they hope treatment will achieve, so do ask them this question.
There has been lots of progress made with melanoma treatments in recent years and many melanoma patients including those with advanced stage cancer are living longer with their disease.
A patients outlook is based on many different factors, not just the stage ( size and extent on the cancer) but also what treatments can be offered, the response to the treatment and the patients general health and fitness levels.
I hope you know more soon and that get a better understanding of what this means for you very soon.
