Most women with the most common form of early-stage breast cancer can safely skip chemotherapy without hurting their chances of beating the disease, doctors are reporting from a landmark study that used genetic testing to gauge each patient's risk.The study is the largest ever done of breast cancer treatment, and the results are expected to spare up to 70,000 patients a year in the United States and many more elsewhere the ordeal and expense of these drugs. "The impact is tremendous,'' said the

Two Korean-American scholars have identified a mechanism in mice that links autism in offspring to a mother’s gut infection during pregnancy, in a discovery that could one day help prevent the development of the condition. Two studies, led by Gloria Choi of MIT and husband Jun Huh of Harvard Medical School and published in Nature on Wednesday, illuminate that pregnant mice exposed to infection develop an autoimmune response which can result in neural developmental problems in their offspring. Th

Thousands of veterinarians gathered Monday in Incheon, west of Seoul, to discuss ways to enhance the health of humans, animals and the environment around the world.In a speech opening the 33rd World Veterinary Congress earlier in the day, South Korean Prime Minister Lee Nak-yon said, "The congress will become an opportunity for mankind to strengthen measures to cope with livestock diseases that are affecting human health."Also attending the opening ceremony of the four-day congress were Agricult

About 83 percent of airborne bacteria found in airborne pollutants like PM 2.5 in South Korea and China overlap, a study found Monday, suggesting that Korea’s fine dust particles may have originated from China. The findings were released by a team of researchers from Seoul National University‘s Graduate School of Public Health, and were from the analysis on bacterial DNA of fine dust concentrations in Seoul, Beijing and Nagasaki in Japan. South Korea is bordered by China to the west and Japan to
