  Thats an interesting question. all mutations are ‘natural’ in the sense they occur in our cells (whether by chance or prompted by chemicals such as found in cigarette smoke). Cancerous mutations are those that contribute to your cells growing beyond your bodies control.
  
  For mutations relevant to natural selection you need germline muations – which are thiose present in your sperm/egg (very rare in cancer!).
