In June of 2001, the American Cancer Society and others reported that almost all cancer rates declined in the 1990s, a reversal of a trend of U.S. cancer rates that had grown for decades. The biggest factor responsible for the decline was said to be decreased tobacco use. For women, there was good news: a decline in new lung cancer cases of 0.2%. But despite all of the comfort we might take from this report, there is a catch: New cases of breast cancer are increasing.
