Children with cancer seem to get more than their fair share of coverage and attention already, although that attention generally doesn't include attributing their cancers to industry.
When the subject is children with cancer, cancer is the enemy. A faceless threat that everyone can stand “against” without hesitation. And this completely misses the critical fact that cancer is often a downstream effect.
I think that cancer awareness really needs to expand to include underlying causes. As it stands, the cause and effect are so disconnected that awareness often leads only to sympathy/empathy/compassion instead of driving people to anger and to push for systemic changes.
So I'm not really sure what the answer is. If the individual cases chosen for awareness campaigns could be selected based on their traceability, it might provide a bridge from cause to effect.
Or maybe it really needs to be a multi-pronged effort. Present individual cases to people care. Separately, present aggregate cases so people start linking those individual stories to systemic factors.
