I Have Been Struggling To Address An Infection In My

I have been struggling to address an infection in my lungs from Pseudomonas Aeruginosa. I have been on four sets of antibiotics over the past 4 months. I have had a CT scan and it shows part of my right lung is 'collapsed'. The CT scan did not rule out the possibility of cancer so I have been referred to a Pulmonary Specialist, Dr. Chan in Calgary however there is a long long wait list. How can I rule out Cancer. Is there a Pulmonary specialist I can get into quickly in Calgary to do the test required to rule out cancer?
