BEIJING, Nov. 22 (Xinhuanet) -- Women aged 40 to 49 are not recommended for routine mammography screening for breast cancer, said the new guidelines issued by the Canadian Task Force on Preventive Health Care in media reports Tuesday.The new guidelines are purposed to direct doctors on using mammography, MRI scans, clinical breast exams and breast self-exams. In principle, they pointed out, there is no need for women to take clinical breast exams and breast self examination if there are no signals for breast cancer.Below are the main points from the guidelines which need special attention from women with reasonable doubt on the matter:Women aged 40-49 who have lower risk for cancer should not take routine mammography because of the higher risk for overdiagnosis, overtreatment and false-positives;Women aged 50 to 69 years and aged 70 to 74 years should go for routine screening every two to three years;And there should be no routine clinical breast exams by doctors and no breast self-exams to screen for breast cancer.Dr. Marcello Tonelli, Chair of the Task Force and Associate Professor at the University of Alberta, remarked: "The main effect of screening is to produce patients with breast cancer from among healthy women who would have remained free of breast disease for the rest of their lives had they not undergone screening.""The best method we have to reduce the risk of breast cancer is to stop the screening program," he added, "This could reduce the risk by one-third in the screened age group, as the level of overdiagnosis in countries with organized screening programs is about 50 percent."

BEIJING, Nov. 24 (Xinhua) -- China's Supreme People's Court vowed to harshly crack down on bribery, abuse of power and malpractice in food safety cases as such illegalities have become top concerns for Chinese people.Chinese courts at all levels had heard 173 cases and sentenced 255 people in relation to the production and sale of unsafe food in the first ten months of this year, Sun Jungong, spokesman of the Supreme People's Court (SPC), said Thursday."China has seen a growing number of food safety cases in recent years with increasing difficulties for investigation," Sun said.According to the SPC, Chinese courts handled 84 food safety cases in 2008, and 148 and 119 cases in 2009 and 2010, respectively. The number of food safety violators sentenced in the past three years totaled 101, 208 and 162, respectively.The SPC also promulgated four typical food safety illegalities exposed in recent years.In the latest food safety scandal, four people in central China's Henan province were prosecuted for the crime of "endangering public security by using dangerous means" in July after they were found to have produced and sold clenbuterol, a poisonous feed additive that pig farms use to boost the output of lean meat.The spokesman said the SPC will strengthen cooperation with police and procuratorial organs to improve the efficiency of dealing with, and preventing food safety crimes.

WASHINGTON, Dec. 7 (Xinhua) -- The use of two drugs never tried in combination before in ovarian cancer resulted in a 70 percent destruction of cancer cells already resistant to commonly used chemotherapy agents, say researchers at Mayo Clinic in Florida.Their report, published on-line Wednesday in Gynecologic Oncology, suggests that this combination, ixabepilone and sunitinib, might offer a much needed treatment option for women with advanced ovarian cancer.Neither drug is approved for use in ovarian cancer. Ixabepilone is a chemotherapy drug that, like other taxane drugs, targets the microtubules and stops dividing cells from forming a spindle. It has been approved for use in metastatic breast cancer. Sunitinib, approved for use in kidney cancer, belongs to a class of tyrosine kinase inhibitors that stops growth signals from reaching inside cancer cells.When caught at late stages, ovarian cancer is often fatal because it progressively stops responding to the chemotherapy drugs used to treat it."Women die from ovarian cancer because their tumors become resistant to chemotherapy, so a drug that might be able to reduce that resistance -- which may be what this combination of agents is doing -- would be a boon to treatment of this difficult cancer," says study coauthor Gerardo Colon-Otero.The finding also highlights the importance of the role of a molecule, RhoB, that the researchers say is activated by the drug duo. It might be a potential biomarker that may help identify patients who might benefit from such combination therapy, the researchers say.

WASHINGTON, Nov. 14 (Xinhua) -- Nearly a fifth of all Americans 12 years or older have hearing loss so severe that it may make communication difficult, according to a new study led by Johns Hopkins University researchers and published Monday in the Archives of Internal Medicine.The findings, thought to be the first nationally representative estimate of hearing loss, suggest that many more people than previously thought are affected by this condition.Study leader Frank Lin, an assistant professor, and his colleagues used data from the National Health and Nutritional Examination Surveys (NHANES), a research program that has periodically gathered health data from thousands of Americans since 1971. The researchers analyzed data from all participants age 12 and over whose hearing was tested during NHANES examinations from 2001 to 2008. Unlike previous estimates, NHANES includes men and women of all races and ages, from cities scattered across the country, so it's thought to statistically mimic the population of the Untied States.Using the World Health Organization's definition for hearing loss (not being able to hear sounds of 25 decibels or less in the speech frequencies), the researchers found that overall, about 30 million Americans, or 12.7 percent of the population, had hearing loss in both ears. That number jumps to about 48 million, or 20.3 percent, for people who have hearing loss in at least one ear. These numbers far surpass previous estimates of 21 to 29 million.Hearing loss prevalence nearly doubled with every age decade, with women and blacks being significantly less likely to have hearing loss at any age. Lin and his colleagues aren't sure why these groups appear to be protected. However, he notes that the female hormone estrogen, as well as the melanin pigment in darker skin, could have a protective effect on the inner ear.

ATHENS, Jan. 20 (Xinhua) - A seven- month- old Libyan baby died in an Athens Children's hospital on Friday in the first fatality linked to the H1N1 flu virus of the new year in Greece, local authorities reported.According to local media reports citing Greek doctors who treated the boy, he had been infected with the virus in Libya, where he was diagnosed with common flu and received insufficient therapy, before transferred to Greece.An Ukrainian woman who is being treated in another Greek hospital for pneumonia is the second severe case of the swine flu to be reported in the country this season.Last year deaths caused by the H1N1 virus in Greece climbed exceeded the 100 victims and many more patients were treated for complications caused by the virus which first emerged in 2009 in Asia and developed into a worldwide pandemic.Greek Centre for Disease Control and Prevention (KEELPNO) experts noted that Greece does not face a high risk so far this year, but suggested to people of vulnerable groups that reach up to 1.5 million persons in Greece, to get vaccinated.Last year's high number of fatalities was attributed to the fact that several people who should have been vaccinated, skimped vaccination which is not obligatory.
