Yeah, I got a little carried away with my arithmetic.
"More people die from lung cancer than any other
type of cancer. In the United States in 2007,*
203,536 people were diagnosed with lung cancer,
and 158,683 people died from it. CDC has a
number of programs for preventing and controlling lung cancer.
"*Latest year for which statistics are available.
USCS is United States Cancer Statistics, maintained by the CDC. Link:
"In the United States, about 90% of lung cancer
deaths in men and almost 80% of lung cancer
deaths in women are due to smoking. Smokers are
10 to 20 times more likely to get lung cancer."
Both quotes are from this link:
