Cancer of the nasel septum inside the nose

Is there anyone who has had this very rare cancer? I have many of the presenting symptoms but also symptoms can vary between people. What were your early symptoms? How long did it take to get a diagnosis? What was your experience with this cancer or other cancers of the nasel septum or nasel cavity? Did you get a biopsy? Did several doctors tell you it doesn't "look" like cancer? I am in contact with 2 people who were also told this and finally got diagnosed.
