Hi, I Found A Brown Spot In My Ear. I

Hi,
I found a brown spot in my ear. I went to the student health service today. Doctor said that maybe it is cancer. I am worried about that. I am wondering if it leads to death after a while?

also, it seems that a takes 6 months just to do a cancer examination. i am wondering if there is a way to do the cancer examination earlier? I dont want to lose a long time just waiting for a cancer examination.
