How To Make A Powerpoint Over Retinoblastoma?

I have to make a powerpoint in AP biology about Retinoblastoma? I know it’s a somewhat rare childhood cancer that develops in the retina of the eye. Honestly, I don’t know how to make a powerpoint over anything, much less cancer. Do I just make it informal? Like what do I do? He also wants us to add a song? Any non-insulting backgound music songs?
