I have concha bullossa in nose. doctor says need operation but he not proving me gaurantee . can't breathe from right nose. is it cancer. please help?

Not cancer,,: This isn't cancer, but it is an air filled cavity in one of the ridges known as turbinates in your nasal passages. This is often associated with a deviated septum in your nose. Because of this, you've got obstruction in your nose stopping you from breathing and can get sinusitis. Surgery is done to clear this. It's a good idea to listen to your doctor and get surgery. Best of luck.
