I noticed a small, white lump on the back of my five-year0old sons left ear about 10weeks ago, since noticing it, it has increased slightly in size. The pharmacist thought it may be a wart as it is hard but the doctor said it looked like cartilage and they would only remove it if it trebles in size. He did seem to say it was cartilage rather quickly, which didn't really put me at ease and the reason for it occurring wasn't explained.
Since seeing the doctor, 3 more of these white lumps have appeared, one just outside my sons nose near the bottom of the nostrils and one inside each nostril.
Does you have any idea what these lumps could be or if it is in fact cartilage? It seems odd to me that cartilage can grow outside of the body as I've not heard of this before ...
What could or should be done about these lumps?
