Brain tumors annual report to the nation

Lung cancer death rates in women have fallen online March 31 published in the journal of national cancer a report on the status of Cancer Institute for the first time in four decades, according to a year. The drop is about 10 years after lung cancer deaths in men began to fall, a delay that reflected the eventual integration of smoking by women in the middle of last century.

The cancer rate death has continued a decline in total, which, which began each year by the National Cancer Institute (NCI), is the North American Association of Central Cancer Registry (NAACCR), centers for disease control and prevention (CDC) published in the early 1990s, according to the report, and the American Cancer Society.

Lead author Betsy A. Kohler NAACCR and colleagues collected information on cancer incidence (new cases) from the NCI, CDC and NAACCR and cancer deaths for statistics on the health of the CDC National Center.

Incidence rates (new cases) as a whole fell according to the report. For certain types of cancer, but increased incidence and/or deaths.

Highlights from this year's report, covers the period from 1992 to 2007, are the following: overall, about 1 percent per year decreased cancer incidence rates and 1.6 per cent per year between 2003 and 2007 was a total average death rates. Increased incidence of liver, kidney, and pancreatic cancer, and melanoma of 2003 up 2007. mortality rates for three of these types of cancer in men - increased liver and pancreatic cancer, and melanoma. Among women, increased incidence of kidney, thyroid, and pancreatic cancer and leukemia and melanoma from 2003 to 2007 increased death rates for pancreatic and liver cancer. Death rates for cervical cancer, after a decline of 1975 by 1997, rose in the following decade. Trends in death rates during the last 10 - and 5-year period (1998 and 2003) fell to seven of the top 15 cancers in men and women (colon and rectum, [malicious] brain, stomach, and kidney cancers and non-Hodgkin's lymphoma leukemia and myeloma); for cancers of the lung, prostate, and oral cavity in men; and for breast and bladder cancer in women. The declines for ovarian, lung and cervical cancers settled the last 5-year period. In children of on cancer rates death a decline which began in the 1970s; However, the incidence of cancer in childhood increases had black men and women by about 0.6 percent per year from 1992 to 2007 the highest death rate as a whole, but also the largest declines in death rates from 1998 to 2007. For new types of cancer, black men had the highest incidence rates as a whole. White women had the highest incidence rates among women.Brain tumors

The this year's report has a special section on brain tumors and contains, for the first time, data on non-malignant brain tumors diagnosed from 2004 to 2007. The authors found that the incidence of glial cells on average 0.4% per year was brain tumors, a kind of common, usually malicious, from 1987 to 2007. This decline offset an increase of 2 percent per year from 1980 to 1987, leave long-term incidence.Other highlights from the brain tumor section of the report: Advisor tumors were about twice as increased, such as malignant tumors in adults aged 20 years and older. Brain tumors in children were much rarer than in adults, but are much more likely to be malicious; 65.2% are malignant in children against 33.7 percent in adults. Tumors of the fabric were the most common type of malignant brain glial cells and glioblastoma tumors was the most common subtype of glial cells. The most common tumor Meningioma, and it was 2.3 times more common in women than in men. final, the authors write that "decline in the overall cancer incidence and death rates in almost all ethnic groups are very encouraging."

Note however, that the number of people in the United States 65 years age group, and people who are at increased risk of many types of cancer, is older, in double size by 2030 compared to 2000.

"Even with declining cancer incidence rates," they write, "The absolute number of individuals of cancer diagnosed continue due to the these population changes...." They conclude that "effective management of the cancer load will require the application of sound offer cancer control strategies in prevention, detection, treatment, and survivorship, as well as resources to good quality of care."
