Cancer screenings not all they're cracked up to be

A recent New York Times story is chilling enough to certainly turn the health care world upside down.

The message: Cancer screenings might not save lives. In a shocking and polarizing move, the American Cancer Society is backpedaling on cancer screenings, amending its previous stance that screenings are invaluable.

By definition, screenings are meant to detect potentially life-threatening tumors. But experts say there's no proof that's happening. Fighting words, some might say, to many cancer patients and survivors.

Record numbers of cancer cases caught early are attributed to mammograms and PSA tests. But experts argue despite that, the number of advanced cancers are not trending downward.
