Skin cancer............?

Please go see a dermatologist like the ER doctor suggested. It would be better than asking people on Yahoo Answers because that way you would know for sure what it is. I don't know about you, but I personally would trust the diagnosis, suggestions or opinions of a doctor much more than those of a random stranger online. It's better to be safe than sorry, especially when it comes to something as serious as cancer. Besides, if it is cancer then it's best to get treated as early as possible.
