Michael Jackson with Skin Cancer? Really? How?!?!?!

I heard Michael Jackson might have skin cancer. His rep already denied the rumors and said that Jackson is in good health but shortly after this, Jackson canceled his appearances until 2010. I am not sure if the skin cancer rumors are real but I have to say I am surprised that there is even a possibility of NOT getting skin cancer after becoming a white man GENETICALLY where even his biological son (claimed to be) is a blonde kid.
