Although the overall rate of NSCLC is lower, certain subtypes of the disease fared better than others, the study published in the journal Cancer found.
Overall lung cancer rates are dropping, according to a new analysis of nearly a half million Americans with lung cancer. But, the news wasn't all good -- the study also found that the rates of certain types of lung cancer are increasing, according to researchers from the U.S. National Cancer Institute (NCI).
Over nearly three decades, the overall lung cancer rate has dropped approximately 12 percent, said the study's lead author Denise Riedel Lewis, an epidemiologist at the NCI.
"The good news is that lung cancer rates are declining. However, it's not as clear for certain subtypes, and we are not exactly sure of the reasons behind these increases," Riedel Lewis said.
Riedel Lewis said that while she cannot draw a definitive conclusion about what's causing the decline in lung cancer rates, she can infer that it's mostly due to decreases in smoking.
