Between 2003 and 2007 of all cancer, death rates fell steadily in America, researchers in the journal of National Cancer Institute reported. At the same time a trend that began in the early 1990's there was an average drop in deaths from all cancers of just under 1% per year.

Lung cancer death rates in women who rise continued for many years, saw its first decline to more than ten years after the male lung cancer rate death began to fall.

The report was drawn up by experts from NAACCR (North American Association of cancer central registries), NCI (National Cancer Institute) and the American Cancer Society.

Diagnosis of malignancies in childhood is still rising, but death rates fall. The authors define a cancer in childhood as one that occurs up to the age of 19 years.

Total, male cancer incidence rates alike have stayed authors wrote. Prostate cancer rates have increased very slightly. In fact, if you exclude prostate cancer, male new cancer diagnoses easily dropped.

There is a special feature editor in the current issue of the journal of National Cancer Institute in the researchers write about the area of the brain and other nervous system cancer and not only to malicious ones, such as such as borderline and benign tumors. In the period 2004-2007, they found that non-malignant tumors twice as often as malicious ones.

Betsy Kohler, executive Director, NAACCR, said:

"Our new data show that non-malignant brain tumours are far more common than malignant brain tumours and affect different sections of the population." Brain tumors have far-reaching effects on our families and friends, but they are difficult to study due to their diversity. "We hope that the collection of both malicious and non-malignant brain tumours of central cancer registries continue to provide a significant source of information and insights to researchers."

"It is gratifying to see the continued steady decline in the overall cancer incidence and death rates in the United States - the result of improved methods for the prevention, detection and treatment of various types of cancer." But the cancer with different trends for different types of cancer, important differences between our different people to prevent different features, diagnosis and treatment of various cancers reported the full repertoire of figures reflects the enormous complexity of today. "Furthermore, as our population to age again, we have to discover a commitment and to provide better ways to control all types of cancer."

Although African-American men and women had the highest death rates of cancer, she showed the largest case between 1998 and 2007.

African-American males had the highest incidence rates for new types of cancer between 2003 and the end of 2007.

Caucasian women had the highest overall cancer rates is diagnosed in women with breast cancer in the most new cancer in all ethnic groups.

The authors added that variations in the mortality rates between ethnic groups, sex and type of cancer of socio-economic status, access to screening and treatment, as well as risk could be affected behavior.

John R. Seffrin, PhD, CEO of the American Cancer Society, said:

"As we work to reduce the burden of cancer in the population as a whole, it is important that we use, what do we know about prevention, detection and treatment of cancer in the population at highest risk." "While it promising, concluded for some race / ethnic groups mortality gaps, are further efforts necessary to prevent the avoidable deaths, representing these gaps."

Lung cancer is still the biggest killer, that inform authors, despite declining deaths in women in the country.

CDC Director Thomas peace, m.d., said:

"Lung cancer can be a rare disease will support States well-funded tobacco programs." "Aggressive advertising campaign, which show the effects of smoking, combined with higher cigarette prices and strong State laws that will protect non-smokers from tobacco smoke, the number of adult smokers and save lives."

Two-thirds of adult brain cancer are not malignant (one third of the childhood of ones). The most common type of brain and nervous system tumors in America are meningiomas.

Modern imaging devices, such as MRIs and CT scans led not only to have less invasive diagnostic techniques, but can also have worked on newly diagnosed cancer rates in the last twenty years.

As new molecular studies improve the classification of brain tumors, treatments have become more efficient and more accurate forecasts.
