U.S. cancer rates drop 22% over past 20 years – 2 de Febrero de 2015 – EEUU

Screenings, advances in cancer prevention and treatment and declines in tobacco use have combined to create good news: Cancer rates have dropped 22 percent in two decades, the American Cancer Society said.

Death rates from four major types of cancer - lung, breast, prostate and colon - drove the decrease, the society reported.

"It's wonderful news," said Dr. Richard Wender, chief cancer control officer for the society in Atlanta. "There's no mystery about how this happened. The biggest factor has been reduction in tobacco use - first in men and then in women."

While rates dropped largely because more people are putting out their cigarettes for good, cancer experts said advancements in screening are also helping save more lives.

Screenings for breast and colon cancer are key, said Cam Scott, senior director of government relations in Texas for the American Cancer Society Cancer Action Network.

"Basically, breast cancer is a curable form of cancer if it is caught early," Scott said. "If breast cancer is caught at an early stage there is a 98 percent survival rate."

The survival rate drops to 24 percent if caught later, Scott said.
