Cancer-related deaths in the United States are dropping — and have been for the past two decades — according to this year's annual report by the American Cancer Society. And some of the largest reductions came in cases involving the biggest killers, including breast, colon, lung, and prostate cancers. The decline came thanks mostly to early detection by increasingly sophisticated screening methods, and advances in treatment. Here's a look at the "changing picture" of the disease, by the numbers:

1 million

Cancer-related deaths prevented since the early '90s

1.8

Percentage that the cancer death rate has declined annually for men

1.6

Percentage that the cancer death rate has declined annually for women

23

Percentage that the cancer death rate fell overall for men since the early '90s

15

Percentage that the cancer death rate fell overall for women since the early '90s

2.6 and 2.5

The percentages the cancer rates have fallen annually since 1998 for black and Hispanic men, the demographic groups that experienced the largest drops

40

Percentage decrease since the early '90s, for men, in deaths related to lung cancer, the United States' number one cancer killer

34

Percentage decrease since the early '90s in breast-cancer-related deaths for women

1/3

The proportion of cancer incidents caused by tobacco use

1/3

The proprotion of cancer incidents related to "being overweight, physical inactivity, and poor nutrition"

1.6 million

New cancer cases expected in the U.S. this year

577,000

Estimated number of people who will die from the disease this year

$24.7 billion

Total cost of cancer treatments in the U.S. in 1987

$48.1 billion

Average annual cost of cancer treatments in the U.S. between 2001 and 2005
