Number of U.S. cancer survivors at all-time high

The number of cancer survivors in the U.S. is at an all-time high, according to an annual report from the American Association of Cancer Research.

The report indicates the number of cancer-related deaths fell by 26 percent during a 14-year period ending in 2015.

The improvement is being attributed to advances in research, treatments and a dramatic decrease in smoking.

The report also notes that outcomes vary greatly between different races, income levels and genders.
