33 of the most dangerous things science has strongly linked to cancer

Business Insider Logo By Hilary Brueck of Business Insider | Slide 1 of 34: 
  Cancer is the No.
  2 cause of death in the US, second only to heart disease.

  It fundamentally affects the way our cells grow and divide,
  changing them in perverse ways. All cancer is a result of damage
  or genetic mutations in our DNA. The nasty, debilitating class of
  diseases spreads through a body like an invading army, as toxic
  cells grow relentlessly into unruly tumors.

  Some cases of cancer are out of our control, determined by
  genetic defects and predispositions passed down from one
  generation to the next, or spurred by genetic changes we undergo
  through our lifetime.

  But we also know that breathing in certain substances, eating
  specific things, and even using some kinds of plastics ups the
  risk of developing some deadly cancers.

  Here are some known carcinogens (cancer-causers), as well as a
  few more things scientists are zeroing in on as prime suspects.
