The only foolproof way to know if it's a mole or skin cancer is to have a professional examine it. But looking for things like symmetry (moles tend to be symmetrical, skin cancer spot tend not to be) can help a layperson tell the difference before visiting his/her doctor. More information in my source.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
