Who is 'people'? They're not the same set, not all of cancer research is looking at people currently 'dying from cancer', nor are there going to be enough from different demographies declaring 'I am concerned about dying from cancer more than my privacy' and volunteering their data. And even if there were, that trait itself is probably skewing your data and not necessarily generalisable to people not (so particularly) concerned about 'dying from cancer'.
