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, Dec. 11 (Xinhua) -- China is faced with severe challenges in collecting enough blood plasma to produce medicines, Health Minister Chen Zhu said Sunday.Chen called on the public to join blood donation after donating blood plasma at the Beijing Red Cross Blood Center on Sunday, the fifth time since he took office in 2007.Blood plasma is needed to make blood products like prothrombin complex which is vital for hemophiliacs.The total volume of blood plasma collected last year was 4,180 tonnes, while the volume needed to produce enough medicines was 8,000 tonnes, said a statement from the ministry. The situation became even worse this year.Donations of blood plasma in China fell dramatically in recent years, as a result of safety concerns from donors and the government's efforts to regulate blood collection after contamination triggered HIV infection scandals.In an overhaul of plasma collection services in 2004, the ministry closed 262 donation centers, leaving only 138 in operation, resulting in the plasma donations falling at least one-third from 5,000 tonnes in 2003.Blood plasma are currently collected at 144 designed stations across the mainland. The stations, as requested by law, are all owned by major manufacturers of blood products.Chen promised to encourage qualified drug makers to set up more collection stations in the next five years.He also assured the public the safety of blood donation at authorized stations.

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.

ADDIS ABABA, Oct. 22 (Xinhua) -- China on Saturday delivered portion of the first batch of emergency food assistance to Ethiopia.Wei Hongtian, Charge d'Affairs at the Chinese Embassy in Ethiopia, handed over the assistance certificate to Wondirad Mandefro, Ethiopian State Minster of Agriculture, in a ceremony held at the Office of the Ethiopian Disaster Risk Management Food Security Sector (DRMFSS) in Addis Ababa, Ethiopia.The handover was witnessed by Ahmed Shide, Ethiopian State Minister of Finance and Economic Development, and Qian Zhaogang, Economic Counselor at the Chinese Embassy in Ethiopia as well as officials and diplomats from the two countries.The charge d'affairs said the Chinese government has decided to provide Ethiopia with two batches of gratis emergency food aid valued at some 24 million U.S. dollars, as part of humanitarian assistance to the people affected by drought in the Horn of Africa region, about which the international community is concerned much.Months ago, China pledged to provide humanitarian aid to drought affected people in Ethiopia, Kenya and Djibouti.The 2011 drought in the Horn of Africa region has affected livelihoods of over 12 million people in countries of the region including Ethiopia.In this move, China has delivered large quantities of wheat to Ethiopia, and it is put in the central warehouse in Adama town, 90 km away from Addis Ababa, as the first batch of the 8,139.4 tons of wheat and 715.15 tons of rice donated by the government of China, said Ethiopian State Minister of Agriculture.According to the minister, the Chinese government has pledged around 20,000 tons of emergency food valued at 24 million dollars.Wei said China attaches great importance to the agriculture development and the food security in Africa. He said China has engaged itself in various agricultural cooperations with African countries including Ethiopia, in different channels."In the future, besides food assistance, China's agricultural cooperation with Africa will focus on technology demonstration, personnel training, infrastructure construction, promotion of agricultural production and trade, and experience sharing agriculture development," said the Charge d'Affairs.The rest portion and the other batch of the emergency food assistance pledged by China is expected to come in November and December.Wei assured that the rest batches of emergency food aid would come to Ethiopia on schedule. The Ethiopian state minister said the Chinese government is one of those donors that demonstrated its strong friendship with the Ethiopian government and its people by extending appreciable humanitarian support at critical time."The recent donation of 100, 000 U. S. dollars by a Chinese private company, Huajin Group Ltd, for food aid is a manifestation that even private companies join us in our efforts to containing problems associated with such natural disasters," said Wondirad."Despite a steady economic growth achieved these past eight years in Ethiopia that reached an average of 11 percent annually and our continued efforts to maintain and accelerate the momentum through the GTP, we are confronted by climate change induced disasters, of which drought remains the major one," said the minister."While reducing disaster risk and vulnerabilities through development interventions, the government of Ethiopia in collaboration with its partners is taking all the necessary measures towards further enhancing its early warning and response system with the view to reducing potential impacts of disasters, including that of drought enhanced preparedness and provision of timely and appropriate responses."The government of the People's Republic of China has been one of our major development partners supporting us in all these efforts," he added.The state minister commended the Chinese government and its people for standing with Ethiopia shoulder to shoulder at the critical time by donating appreciable size of emergency food aid.
