Catron Courier - - Opinions & Editorials -

Heard th­ese be­fore? “Be­come a veg­e­tar­ian. Work our reg­u­larly. Al­ways ap­ply sun­screen. Never drink al­co­hol. Stop smok­ing?” Th­ese are the mes­sages we’ve re­ceived as the sure-fire way to re­duce our chance of get­ting can­cer. It turns out that th­ese are the ma­jor causes of can­cer af­ter all.

A re­cent study from Johns Hop­kins Uni­ver­sity has determined that 66% of all can­cers are caused by ran­dom gene mu­ta­tions. In other words, can­cer is mostly caused by good old-fash­ioned bad luck.

And th­ese mu­ta­tions aren’t ex­actly ran­dom. They oc­cur much more of­ten in peo­ple who are ex­posed to tox­ins in food, air, wa­ter, caus­tic chem­i­cals at home or at work, and other un­healthy con­di­tions.

Does this mean that you should keep smok­ing? No. It turns out that the re­main­ing 33% of can­cers heav­ily in­flu­enced by be­hav­ior. If you do re­duce smok­ing and ex­po­sure to the sun you’ll cer­tainly re­duce the chances of get­ting those types of can­cers.
