Regardless:
In 2013, 1,660,290 people are expected to be diagnosed with cancer.
In 2013, 580,350 people are expected to die from cancer.

Did these people die by their choice also? Maybe they should have eaten more vegetables and exercised more? That's 116 times more deaths in one year than have died by terrorism in 148 years.
If we had 240,000 employees working on cancer prevention, screening, treatment and cures do you think we might be able to bring that cancer death number down by 1%? That would save 5,800 lives per year which is more than the last 148 years have killed by terrorism. (Department of Homeland Security has 240,000 employees, improving screening processes alone would likely reduce cancer deaths by 1% per year).
