That's the number of U.S. residents expected to get a cancer diagnosis in 2018 — 1,735,350, to be exact. The projection comes from the American Cancer Society's new annual report, released Jan. 4, on cancer incidence, mortality and survival. The number of new cancer cases has remained fairly stable over the past decade. Deaths from cancer, however, have continued to decline. The latest data show an annual drop of 1.5 percent in the cancer death rate.Since 1991, deaths attributable to cancer have declined by 26 percent. According to the ACS, that means roughly 2,378,600 fewer people died of cancer over that time than if the death rate had not declined by that much. The most likely reasons are a decline in smoking, earlier detection of cancer and improved treatments.
