Little voice - no-one has spoken to me about my diagnosis

Completely stressed by months of (traumatic and privacy invading tests) for lung and lymph node cancer. As yet, I still have not had an opportunity to discuss this with anyone from the medical profession. I have no idea how advanced it is. It now seems that an assumption has been made that I will be having surgery. A confirmation letter received today, for what I was told was a 30 minute consultation with respiratory, expects me to 'wear easily removed clothing' and have a pre op assessment. Is there ever a time  when my voice will be heard?
