I was treated for asthma by 3 different doctors for 18 months only to find out I have a malignant tumor in my airway. Do I have a case of any sort?

I was having breathing problems after a bad cold, so I went to my local Urgent Care center and was given asthma/allergy treatments and medicine. When that didn't work I went to a regular doctor and was again treated for asthma. When that didn't work I went back to the doctor and he referred me to an allergy/asthma specialist. After several tests were performed she was not sure what it was. She sent me the ER where I was diagnosed with orthoapnea. I got frustrated because I still couldn't breathe, I was losing sleep and missing work. I stopped seeing doctors for several months and when my symptoms got worse I went back to my family doctor. He sent me to another specialist who treated me with the same drugs as the other doctors only he also requested a CT scan. The scan showed a mass in my left mainstem bronchus and from that, a series of tests were performed. These test confirmed that I have a slow growing cancerous tumor that is taking up more than 90% of my airway.
