Cancers tied to HPV, obesity on the rise, says report

Cancer rates in the United States continue to fall, according to a new government report, with the exception of certain cancers linked to increasingly common health woes facing Americans.
The new report, which tracked U.S. cancer rates from 1975 through 2009, found increases in incidence of cancers related to obesity and those linked to human papillomavirus (HPV).
The "Annual Report to the Nation on the Status of Cancer" is a joint project from researchers at the government's Centers for Disease Control and Prevention and National Cancer Institute, in addition to the American Cancer Society and North American Association of Central Cancer Registries. It was published Jan. 7 online in the Journal of the National Cancer Institute.
Fewer Americans have been dying of cancer since about 1990, and the new report found cancer death rates continued to drop from 2000 to 2009, by about 1.8 percent per year among men and 1.4 percent per year among women over that time period.
Men were less likely to die from 10 of the 17 most common types of cancers, including lung, prostate, colon, stomach cancers and leukemia, while cancer death rates for women fell for 15 of the 18 most common types of cancers, including cancers of the breast, cervix, ovary, bladder and lung.
The researchers said these declines in cancer death rates may be because of reductions in risk factors like smoking and improvements in early detection and treatments.
Cancer death rates among children 14 and under also fell overall by 1.8 percent.
