Can cartilages over the MOVE over the years? What is and what causes "weak" nasal cartilage? Can you break nose cartilage?

If you break your nose and have breathing issues from deformed cartilage or you get rhinoplasty and a surgeon does a bad job of suturing cartilage. What are the odds your nose changes in a few years?  I constantly have to blow and manipulate it and sometimes even hold my nostrils in to get air. I recently had trauma to my nose and had an Xray, ENT said my bone was NOT broken. He said the Xray cannot detect cartilage so the cartilage may be broken. What does this mean? Can it heal over time?
