Just because it is changing doesnt mean that it has turned into cancer. my son has a very large NS on his face and the back of his head. He has had two growths already that have need to be removed because they were in a spot were it irratated him. They were non cancerous. Definitly get into see your ped derm to have it checked out. I hope this helps.
i have new pics of my son posted you guys should check them out and give me some kind of response
