This reasoning is flawed because “destructive” is a matter of perspective.  
As you have indicated, effects of potentially hazardous environmental 
conditions on cells can result in mutations that have a positive effect on 
the development of a species in the long run, enabling it to adapt better to 
its surroundings.

As always, it is a matter of the dosage.  A tumor as the result of an 
abnormal cell function is only considered cancer if its starts spreading and 
impeding the function of an organism.  I think there is not enough knowledge 
and research about the causes of cancer yet to support your argument.
