US Blacks Hard-hit by Cancer
Death rates for cancer are falling for all Americans,but black Americans are still more likely to die of cancer than whites,the American Cancer Society said Monday.
In a special report on cancer and blacks,the organization said blacks are usually diagnosed with cancer later than whites,and they are more likely to die of the disease.
This could be because of unequal access to medical care,because blacks are more likely to have other diseases like diabetes as well,and perhaps because of differences in the biology of the cancer itself,the report added.
“In general,African Americans have less likelihood of surviving five years after diagnosis than whites for all cancer sites and all stages of diagnosis,”the report said.
“In describing cancer statistics for African Americans,this report recognizes that socioeconomic disparities and unequal access to medical care may underlie many of the differences associated with race.”
The Cancer Society said blacks should be encouraged to get check-ups earlier,when cancer was more treatable,and it said more research is needed to see if biological differences play a role.
“The new statistics emphasize the continuing importance of eliminating these social disparities through public policy and education efforts,”the organization said in a statement.
But it also noted a drop in cancer death rates.
“Cancer death rates in both sexes for all sites combined have declined substantially among black Americans since 1992,as have incidence rates,”said the report.
“Increased efforts to improve economic conditions in combination with education about the relationship of lifestyle choices to cancer could further reduce the burden of cancer among African Americans.” About 36 million Americans describe themselves as black,representing about 12 percent of the population.

Black Americans are more likely to die of cancer than________.
A:.people in other countries
B:.white Americans
C:.all other Americans
D:.their ancestors

Study Says Dogs Can Smell Cancer
Dogs are known for their sense of smell. They can find missing people and things like bombs and illegal drugs .Now a study suggests that the animal known as man's best friend can even find bladder（膀胧）cancer.
Cancer cells are thought to produce chemicals with unusual odors（气味）.Researchers think dogs have the ability to smell these odors,even in very small amounts,in urine（尿）.The sense of smell in dogs is thousands of times better than in humans.
The study follows reports of cases where,for example,a dog showed great interest in a growth on the leg of its owner. The mole（痣）was later found to be skin cancer.
Carolyn Willis led a team of researchers at Amersham Hospital in England.They trained different kinds of dogs for the experiment. The study involved urine collected from bladder cancer patie nts,from people with other diseases and from healthy people.
Each dog was tested eight times.In each test there were seven samples for the dogs to smell.
The dog was supposed to signal the one from a bladder cancer patient by lying down next to it.
Two cocker spaniels（短腿长毛垂耳小猎犬）were correct fifty-six percent of the time. But the scientists reported an average success rate of forty-one percent.
As a group,the study found that the dogs chose the correct sample twenty-two out of fifty-four times .That is almost three times more often than would be expected by chance alone.
The British Medical Journal published the research .In all,thirty-six bladder cancer patients and one hundred and eight other people took part.
During training,all the dogs reportedly even identified a cancer in a person who had tested
healthy before the study.Doctors found a growth on the person's right kidney（肾）.
Bladder cancer is the ninth most common cancer worldwide.The International Agency for Research on Cancer says this disease kills more than one hundred thousand people each year. Doctors say cigarette smoking is the leading cause of bladder cancer.

The person who had tested healthy before the study______.
A: dropped out
B: passed away
C: was found to have cancer
D: was found to remain healthy

Food and Cancer

Medical experts have suspected for many years that there is a strong link between what a person eats and
cancer. They say a new study provides the first evidence that vitamins could reduce a person's chance of
developing cancer. A team of Chinese and American scientists did the study.They are from American
National Cancer Institute and the Cancer Institute of the Chinese Academy of Medical Sciences in Beijing.
The Journal of the National Cancer Institute published the results of the study. About thirty thousand people
between the ages of 40 to 69 took part in the study.They were from the northern central Chinese area of
Linxian.Most of them took vitamins and minerals everyday for five years.
Linxian was chosen because the people there have an extremely high rate of cancer of stomach and
esophagus.Researchers believe that fungus and molds in local foods may be partly responsible for the high
cancer rate.Researchers divided those people into eight groups.Seven of the groups received different
mixtures of vitamins and minerals daily.The amounts of the vitamins and minerals were 1 to 2 times greater
than what American health officials say is needed.The eighth group received sugar pills that had no effect.
Those who seemed to gain the most received a mixture of a form of vitamin A called β-carotene,vitamin E
and the mineral selenium（硒）.The vitamin and mineral are believed to prevent damage to cells caused by
cancer-causing substances.Researchers reported a 1 3 percent drop in cancer rates in those who took
β-carotene,vitamin E and selenium.They also found a 10 percent drop in the number of deaths caused by
strokes from bursting blood vessels.
Scientists warn that it is too soon to know if the effect would be the same among people in other
countries.They note that the people in Linxian eat foods that lack necessary vitamins and minerals.Chinese
officials will continue to record the health records of the people in Linxian for many years.For now officials
reportedly are considering using the results of the study.They want to find a way to improve the health of
people in Linxian and other small towns in China.

The rate of cancer of stomach and esophagus in Linxian is the highest in China.

Breast Cancer Deaths Record Low

The number of women dying from breast cancer has fallen to a record low by dropping under 12,000 a
year for the first time since records began.
The Cancer Research UK data showed that 11,990 women died in the UK in 2007.
The previous lowest figure had been recorded in 1 97 1一 the year records began一after which it rose
steadily year by year until the late 1980s.
Professor Peter Johnson,Cancer Research UK's chief clinician,said,"It's incredibly encouraging to see fewer
women dying from breast cancer now than at any time in the last 40 years,despite breast cancer being diagnosed
more often."
"Research has played a crucial role in this progress,leading to improved treatments and better management
for women with the disease."
" The introduction of the NHS（国民保健制度）breast screening program has also contributed as the
earlier cancer is diagnosed,women are more likely to survive."
Breast cancer is now the most common cancer in the UK with 45,500 women every year diagnosed with
the disease一a 50% rise in 25 years.
The number of deaths peaked in 1989,when 15,625 women died.It then fell by between 200 and 400
deaths each year until 2004.
There was a slight rise in 2005 and then two years of falls.
Dr. Sarah Cant,policy manager at Breakthrough Breast Cancer,said,"It is great news that fewer women
are dying from breast cancer and highlights the impact of improved treatments,breast screening and
awareness of the disease."
"However,there are still too many women affected and the incidence of the disease is increasing year by
year.,,
The rising rate of breast cancer diagnosis has been put down to a variety of factors including obesity
（肥胖）and alcohol consumption.

Cooking Oil Fumes Cause Tumor
The leading cause of lung cancer among women in the city was cooking oil fumes while men are more likely to develop the disease from smoking,said medical experts after a five-year research study.
Doctors announced the results yesterday with analysis on some new tendencies in lung cancer. They said patients are younger,especially women.
According to the Shanghai Tumor research Institute,more local residents die of lung cancer in the city than anything else.Following breast cancer,it has the second-highest incidence rate.
“An unhealthy lifestyle is a very important reason for lung cancer,”said Dr He Yumin from Shanghai Minshen Traditional Chinese Medicine Tumor Diagnosis and Treatment Center.
He followed 2,276 lung cancer patients for five years.Among them,1,483 were male.
Smoking causes 70 percent of cases among men while only 18 percent of female patients developed cancer from smoking or inhaling second-hand smoke,according to the report.
However,more than 60 percent of women with the disease had long term,close contact with strong oil fumes from cooking and complained about irritated eyes and throat.
About 32 percent of women fried foods in boiling oil in unventilated kitchens and about 25 percent of women's bedrooms were adjacent to the kitchen.
However,local women were surprised to learn cooking oil fumes could lead to cancer.
Some claimed they may change food preparation methods.
“Unless my family and I don't eat at home every day,I must stay in the kitchen to cook,”said Xu Li,a 45-year-old local woman. “I know the fumes are bad for the skin,but it is the first time I heard that it can result in lung cancer. I have already started frying less.”
Doctors said women's lung cancer had few links to personal health and physical condition,but was closely related to family cancer history,unhealthy dietary habits and weak immune systems.
Other experts agreed with him.
“Smoking is by far the biggest cause of lung cancer for men,”said Dr Tan Binyong, honorary president of the Respiratory Disease Institute at Fudan University's Medical College.“It's true that second-hand smoke and cooking fumes are the main causes among women.”
His research also warned people not to stand near of stalls selling fried foods due to the poor quality of oils used.
The chance of catching lung cancer is three times higher if exposed to the fume for a long time,6 experts said.

What a new tendency in lung cancer is concluded by the researchers?
A: Men are more likely to develop lung cancer than women.
B: Women are more likely to develop lung cancer than men.
C: Patients with lung cancer become older,especially males.
D: Patients with lung cancer become younger,especially females.

The number of deaths peaked in 1989,when 15,625 women died.It then fell by between 200 and 400
deaths each year until 2004.
There was a slight rise in 2005 and then two years of falls.
Dr. Sarah Cant,policy manager at Breakthrough Breast Cancer,said,"It is great news that fewer women
are dying from breast cancer and highlights the impact of improved treatments,breast screening and
awareness of the disease."
"However,there are still too many women affected and the incidence of the disease is increasing year by
year.,,
The rising rate of breast cancer diagnosis has been put down to a variety of factors including obesity
（肥胖）and alcohol consumption.

Breast cancer is more common in the UK than in many other countries.

Breast Cancer Deaths Record Low

The number of women dying from breast cancer has fallen to a record low by dropping under 12,000 a
year for the first time since records began.
The Cancer Research UK data showed that 11,990 women died in the UK in 2007.
The previous lowest figure had been recorded in 1 97 1一 the year records began一after which it rose
steadily year by year until the late 1980s.
Professor Peter Johnson,Cancer Research UK's chief clinician,said,"It's incredibly encouraging to see fewer
women dying from breast cancer now than at any time in the last 40 years,despite breast cancer being diagnosed
more often."
"Research has played a crucial role in this progress,leading to improved treatments and better management
for women with the disease."
" The introduction of the NHS（国民保健制度）breast screening program has also contributed as the
earlier cancer is diagnosed,women are more likely to survive."

Global Cancer Rates to Rise by 50% by 2020

The number of new cancer cases worldwide is expected to increase by 50%by the year
2020.But a new report suggests that as many as a third of new cancers could be avoided
by adopting healthier lifestyles and through public health action.
The World Cancer Report,released by the International Agency for Research on
Cancer,shows that cancer has now emerged as a major public health threat in developing
countries as well as rich ones.
Overall,cancer was responsible for 12%of all deaths in 2000.But in many countries
more than a quarter of all deaths are caused by cancer.
The report shows that 1 0 million new cancers were diagnosed globally in 2000,and that
number is expected to rise to 15 million by 2020.Researchers say most of that increase will
mainly be due to steadily aging populations in both developed and developing countries and
current trends in smoking and other unhealthy habits.
"Cancer has emerged as a major public health problem in developing countries for the
first time, matching its effect in industrialized（工业化的）countries , " said researcher Paul
Kleihues,MD,director of IARC,in a news release."Once considered a'Western'
disease,the Report highlights that more than 50 percent of the world's cancer burden,in
terms of both numbers of cases and deaths,already occurs in developing countries."
The risk of being diagnosed with cancer in developed countries is double that in less-
developed ones.However,the risk of dying from cancer is much higher in developing
countries , where 80% of cancer patients already have late-stage incurable tumors（肿瘤）
at the time of diagnosis.
Researchers say cancer rates have traditionally been higher in developed countries due
to greater exposure to tobacco,occupational carcinogens（致癌物）,and an unhealthy
Western diet and lifestyle.As less-developed countries become industrialized and more
prosperous,they tend to adopt the high-fat diet and low physical activity levels typically seen
in the West,which increase cancer rates.

The risk of dying from cancer in developed countries is
A:double that in developing countries.
B:much higher than that in developing countries.
C:the same as that in developing countries.
D:much lower than that in developing countries.

Food and Cancer

Medical experts have suspected for many years that there is a strong link between what a person eats and
cancer. They say a new study provides the first evidence that vitamins could reduce a person's chance of
developing cancer. A team of Chinese and American scientists did the study.They are from American
National Cancer Institute and the Cancer Institute of the Chinese Academy of Medical Sciences in Beijing.
The Journal of the National Cancer Institute published the results of the study. About thirty thousand people
between the ages of 40 to 69 took part in the study.They were from the northern central Chinese area of
Linxian.Most of them took vitamins and minerals everyday for five years.
Linxian was chosen because the people there have an extremely high rate of cancer of stomach and
esophagus.Researchers believe that fungus and molds in local foods may be partly responsible for the high
cancer rate.Researchers divided those people into eight groups.Seven of the groups received different
mixtures of vitamins and minerals daily.The amounts of the vitamins and minerals were 1 to 2 times greater
than what American health officials say is needed.The eighth group received sugar pills that had no effect.
Those who seemed to gain the most received a mixture of a form of vitamin A called β-carotene,vitamin E
and the mineral selenium（硒）.The vitamin and mineral are believed to prevent damage to cells caused by
cancer-causing substances.Researchers reported a 1 3 percent drop in cancer rates in those who took
β-carotene,vitamin E and selenium.They also found a 10 percent drop in the number of deaths caused by
strokes from bursting blood vessels.
Scientists warn that it is too soon to know if the effect would be the same among people in other
countries.They note that the people in Linxian eat foods that lack necessary vitamins and minerals.Chinese
officials will continue to record the health records of the people in Linxian for many years.For now officials
reportedly are considering using the results of the study.They want to find a way to improve the health of
people in Linxian and other small towns in China.

All those people who took part in the study received vitamins and minerals.
