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 nost 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

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.

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］ess 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 dispari-
ties 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 is more
treatable,and it said more research was needed to see if biological differences play a role.

Lung Cancer
1 The death rate due to cancer of the lungs has increased more than 800 percent in males and has more than doubled in females during the last 25 years.It is considerably higher in urban and industrial areas than in rural districts.There are many possible causes,but it is still controversial which are most blameworthy.Those factors which have been mentioned most frequently are the presence of foreign particles and other irritants in the air(smoke particles,smog,exhaust fumes),and the smoking of cigarettes and cigars.
2 Numerous studies have demonstrated a striking correlation between the death rate from lung cancer and smoking habits.Among heavy smokers-21 to 30 cigarettes per day-the mortality rate from lung cancer is nearly 17 times the rate from nonsmokers.It is expected the death rate among women will increase as the present high rate of smoking among women has its effect.
3 Sometimes cases of lung cancer are discovered at the time an X-ray is taken for the purpose of detecting tuberculosis.Too often,however,a current emphasis upon the danger of exposure to radiation from x-ray machines can frighten people away from routine chest X-rays and thus prevent an early diagnosis of lung cancer.Early detection is absolutely essential if any possibility of cure is to be maintained.Modern X-ray machines in competent hands pose such slight danger,at least to those over 40 years of age,that this would be much more than offset by the advantages of discovering a tumor while it is small enough to be completely removed.
4 A common form of lung cancer is bronchogenic carcinoma,so-called because the malignancy originates in a bronchus.The tumor may grow until the bronchus is blocked,cutting off the supply of air to that lung.The lung then collapses,and the secretions trapped in the lung spaces become infected,with a resulting pneumonia or the formation of a lung abscess.Such a lung cancer can also spread to cause secondary growths in the lymph nodes of the chest and neck as well as in the brain and other parts of the body.The only treatment that offers a possibility of cure,before secondary growths have had time to form,is to remove the lung completely.This operation is called pneumonectomy.
5 Malignant tumors of the stomach,the breast,the prostate gland and other organs may spread to the lungs,causing secondary growths.

The more cigarettes one smokes,______.
A:before the cancer cells spread elsewhere
B:the more chances of dying of X-ray radiation he will have
C:what is most responsible for lung cancer
D:as some people imagine
E:the more chances of getting lung cancer he will have
F:which form of lung cancer is a common one

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.

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

The research by Blackburn and Greider helps suggest the role of

A money in medical research.
B proteins in cancer treatment.
C hormones in the functioning of life.
